Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to telecommunications.

【0002】

[Conventional technology]

Mobile phones provide more opportunities for people to talk to people, especially when they are in public places.

【0003】

This enhanced conversational ability is an easy means of speaking and is expressive, but at the same time has some negative aspects caused by the noisy behavior.

【0004】

There are several possible actions that people can take when placed in a private conversation situation while in a public place. The first method is for individuals to speak loudly. This method requires determination if privacy is not a top priority, or if the conversation is tolerated in certain circumstances or is considered too important to be heard. ..

【0005】

The second method is for individuals to have a quiet conversation. It's not uncommon to see someone using a phone in the corner of a room to block a conversation (from others). This is often inconvenient for users at both ends of the phone, and again requires a determination of when this method works properly.

【0006】

The third method is for the individual to move the conversation elsewhere. It is not uncommon to see people leaving the room with their cell phones in their hands. However, the movement itself is a distracting act, especially when the attention of the person using the phone is focused on the conversation rather than on the action (eg, slamming the door). Also, movement is often accompanied by interruptions in conversation (eg, "Hello, how are you?", "Wait a minute", etc.).

【0007】

The fourth method is for individuals to use inaudible (non-speech) technology. When switching the conversation to a different modality (pager) such as a two-way text pager (pager), no sound is produced. However, all participants in the conversation must be willing to switch to a new modality and be able to do so.

【0008】

The fifth way is for individuals not to receive calls. Voicemail is a traditional way to handle a call when the recipient is busy. However, some calls must be answered.

【0009】

Sixth, in addition to privacy and interruption issues, recent observations of the use of mobile phones in public places reveal other disadvantages of mobile communications. Users have a quick but informative conversation when their attention needs to be immediately directed to something else (eg listening to important broadcasts and passing through traffic). It may be necessary to move away from.

【0010】

Therefore, sometimes it is necessary to properly suspend or completely suspend the call through a very simple dialogue.

【0011】

[Problems to be Solved by the Invention]

Therefore, it is desirable to provide a system and method for carrying out a call in a public place without the above-mentioned disadvantages.

【0012】

[Means for solving problems]

The present invention allows people to easily, expressively and quietly talk when using mobile telecommunications equipment in public places.

BEST MODE FOR CARRYING OUT THE INVENTION

I. Overview The methods and systems described herein (commonly known as "QuietCall" or "silent call technology") allow participants in public places to communicate in a silent mode (eg, for example). Move to keyboard, buttons, touch screen). All other participants can continue to use their audible technology (eg telephones) on their normal telecommunications infrastructure. In embodiments of the present invention, a user's silent input selection can be transmitted directly to other participants in the conversation with a synonymous audible signal (eg, a voice signal delivered directly to the jack of a mobile phone microphone). ).

【0035】

An embodiment of a silent call system is shown in FIG. System 10 includes a vocalized area 11 with an individual 16 and an unvoiced area with an individual 17, i.e. a public area 15. Individual 16 attempts to communicate with Individual 17 on the telecommunications infrastructure 12. Specifically, the individual 16 dials the telephone 13 of the individual 17 using the telephone 18. The silent call technology 14 allows the individual 17 to have an audible conversation with the individual 16 in silent mode without interfering with the dialogue / interaction in the silent area 15.

【0036】

A. Advantages Embodiments of the present invention have at least the following advantages with respect to both sending and receiving telephone calls. First, the conversation is silent to users in the silent area. Non-audible input operations (key or button presses, display touches) are converted into appropriate voice conversation signals.

【0037】

Second, the conversation is audible to other users in the vocal area. Only participants in public places need to opt for alternative communications. Other users join as they would on any other phone.

【0038】

Third, possible conversations are expressive. Expressive expressions for different types of conversations (eg, a list of phrases (such as "yes", "no", "maybe") suitable for greetings and answers to basic questions) can be defined. .. Conversational structures may be predefined, recorded as needed, or synthesized and generated on demand (eg, text to speech).

【0039】

Fourth, this communication interface is easy to use when the user is engaged in other activities. This interface includes conversational expressions so that they are easy to recognize (eg, icons, text labels) and easy to launch (eg, point and click). A single input selection (eg, button press) calls up a potentially complex response sequence that supports the conversation (eg, the action of politely holding the other person on hold or politely ending the conversation). Can be done.

【0040】

Fifth, the communication interface is suitable for the situation. This interface is designed to be unobtrusively adapted to a variety of public or silent situations (eg, a conference-friendly pen interface where it is common to write down notes). Phone users often use a pen / paper while talking on the phone (for example, writing notes on the itinerary before hanging up or using printed matter and laptops during a conversation in the lounge. Use it). The calling interface is designed to be effective in conversations in which the act of writing down notes and the act of inquiring are mixed.

【0041】

Sixth, embodiments of the present invention work within the existing communication infrastructure. One embodiment uses available resources that an individual may have (eg, a PC, PDA, mobile phone with data processing capabilities) and / or is inexpensive to assist in the conversion of conversations. Add and use the components of. Interfaces can be implemented on a wide variety of hardware that can be exchanged during or between calls and can be shared with each other over existing communication channels (eg,). Several participants in a conference call may have different silent mode solutions).

【0042】

A wide variety of private conversations can be supported in a variety of public, lively or quiet situations, such as conference / exhibition venues, general meetings (eg, main conferences). , Keynote speech), "line up" situations (eg ticketing, registration, baggage claim), information meetings (eg business negotiations, technical summaries), large transportation (eg buses, trains, planes), lobby / Waiting room, meetings that require notes (eg technical meetings, product descriptions), parking lots, personal transportation (eg taxis, car pools, shuttles), restaurants, shops (eg doorways, changing rooms, etc.) Includes aisles), streets, and theaters.

【0043】

B. Communication scenario A wide variety of communication scenarios are supported, but not limited to, as shown below. First, a person can have general conversations in public, including simple questions and answers, arrangements for a call back, and receipt of information.

【0044】

Second, it is possible to have topic-specific conversations, including sending and receiving orders or instructions, with questions and answers about selected and predefined topics such as agenda, status, etc.

【0045】

Third, it is possible to use the call postponement function (for example, "Call back" button or "Please wait" button).

【0046】

Fourth, an embodiment of a silent call can function as an answering machine for a mobile phone (ie, play a greeting and listen to a message recorded by the caller).

【0047】

Fifth, an embodiment of a silent call can interrupt the call (ie, play a greeting and listen to the caller's words before deciding to join the conversation).

【0048】

Sixth, an embodiment of a silent call acts as a representative attendee, in which a party acts as an intermediary for those who are listening to an event or conference remotely. The representative attendee is present where the silent call is in progress, but the silent call user keeps the phone microphone on (normal for silent calls) so that other callers can hear it. Not in mode). Thus, a user of a silent call can quietly interact with the caller in this way, expressing his or her interest (eg, at a meeting) or in an ongoing situation. You can quietly get the person's opinion about.

【0049】

Seventh, the silent call is the reporter of the activity, and when the button conveys information through the dialogue in silent mode (for example, when you click the "Meeting" button on the silent call interface, the phone says "I am now. ... I'm attending a meeting ... This meeting should end in about ... 15 minutes ... ").

【0050】

C. Silent call conversation example Ed, a manager at a large engineering company, attends an all-day meeting on quarterly performance evaluations of the company's ongoing projects. He and many of his colleagues are flying to attend a series of presentation and Q & A sessions.

【0051】

At the same time, Ed's project is at an important decision-making turning point that requires comparative analysis of several different methods. Sue, the technical leader of the project, is "calculating numbers" with the rest of the project. As the technical debate progresses, Sue will continue to inform Ed of the progress and will require several different conversations with Ed to obtain his consent when necessary. Sue knows that she can contact Ed through a silent calling system.

【0052】

When Sue first makes a call, Ed sets his phone for silent alerts. Ed is just trying to raise a question, so he quickly talks to Sue with a single click that gives Sue the utterance "I can't speak now, so I'll call you back as soon as possible." put off. The silent call system allows Ed and Sue to quickly postpone a call without spending unnecessary time on the voicemail system.

【0053】

When the next speaker changes, Ed calls Sue and quietly issues (silently to the outside) instructions that he can hear on the phone that he is still in silent mode. Inform. He doesn't want to leave the room for a phone call because it can take too long. Ed uses his earphones to hear Sue convey her information. Ed signals that he understands and hangs up. When Ed gives a presentation on his own project, he has the latest technical information available. The silent call system allows Ed to get information in an unobtrusive way.

【0054】

Later, the next time Sue makes a call, she needs Ed's decision as to whether to do it or not. Sue gives her recommendation and Ed signals his consent. Ed then types a brief note indicating that he will be available at 1:30 pm to hear the full report. The ability to convert the text of an unvoiced call to voice voices the message, and they both hang up. The silent call system allows Ed and Sue to exchange information easily and quickly.

【0055】

Sue doesn't have the opportunity to call until 2:15 pm. When she contacts Ed, he signals that he has just been outlined about the project currently being introduced and will be out soon so please wait a moment. Ed unplugs his phone from the silent calling system by simply unplugging it, quietly exits the conference and talks on his cell phone just like a regular cell phone. The silent call system allows Ed to switch conversation modes as needed without interrupting the flow of conversation.

【0056】

At the end of the meeting, a new project was introduced, and Ed finds that he and Sue have been working on a problem with the decisions the project is making. Ed hurriedly calls Sue and activates the microphone on his silent calling system so that Sue can hear him. Sue tells Ed that this new information is relevant to them only if the other project has a built prototype. Ed will ask about the status of development at the next opportunity. The silent calling system allows Ed to share information in an unobtrusive and interactive manner.

【0057】

He meets Sue as Ed waits for a regular flight to get home at the airport at 5:30 pm. Ed doesn't want people in the crowded lobby to know about his work, so he plugs into a silent calling system and revisits what happened that day. As they interact, broadcasts about plane delays begin to play through the speakers. Ed immediately interrupts the conversation and informs Sue that he has been interrupted for another by pressing one button. The silent calling system allows Ed to have a confidential conversation and, if necessary, pay attention to what is happening around him.

【0058】

II. Silent call system The silent conversations described herein are electronically assisted discussions (eg, telephone calls) between two or more callers and have the following attributes:

【0059】

Conversations are expressed, at least in part, by voice (eg, via telephone, mobile phone, internet telephone, videophone, two-way radio, intercom, etc.).

【0060】

One or more participants in a conversation are in an inappropriate, unintended, or undesired situation for some reason (eg, a meeting, theater, waiting room, etc.).

【0061】

Thus, one or more participants in a discussion use an alternative silent mode of discussion (eg, keyboard, buttons, touch screen, etc.) to generate audible content for the discussion. This audible content is translated into a synonymous electronic representation that can be transmitted silently to other participants in the conversation.

【0062】

The term "silent call technology" is used herein as hardware and / or software that allows people to talk easily, expressively, and quietly when they are out and about. It is used to represent a communication mechanism that includes. A silent mode conversation or a silent conversation is a conversation made using this technique.

【0063】

In one embodiment of the present invention, two silent call operation modes are defined. That is, 1) execution of a silent call, and 2) preparation for a silent call.

【0064】

A. Executing a silent call FIG. 3 is a simplified block diagram of the structure of the components of an embodiment of a silent call system used to perform a silent call. In this mode, the user carries out a conversation on the mobile phone, but the local user does not speak aloud, so the local user does not directly generate audible content around him. Examples of using a silent call system in this mode include silent communication while attending a meeting and performing confidential conversations in a public environment.

【0065】

The user looks at the conversational expression shown in block 31 of FIG. 3 and makes a choice regarding the utterance to be voiced over the telephone. In one embodiment, the conversational expression 31 can be an icon with a text label as shown in FIG. The conversation element 33a associated with the conversation expression 31 is stored in the speech data storage device 33, and when the conversation element 33a is selected, it is searched and passed to the voice generator 34, which is required for the telephone connection. An output signal is generated. An audio-to-phone connector 35 provides this electrical connection. Phone-to-user connector (telephone-to-user connector) 30 allows the user to hear conversations generated by both the system and other users. In one embodiment, the telephone-to-user connector is an earphone. The switchable voice input 36 (via switch 37) allows the user to speak directly to the phone, where appropriate. The stored data extraction device 32 converts data stored in another format (for example, a PC calendar entry (input item of a schedule table), an address book) into a format suitable for voice generation.

【0066】

The components in the embodiment of the silent call system will be described below.

【0067】

i. Components of the silent call system a. Conversational expression A conversational expression 31 of a conversational element 33a (ie, a phrase, a word, a letter, a number, a symbol, a sound effect, and a sequence and / or combination thereof) that the user can call to start speaking the conversation is given to the user. Is displayed. An example of a conversational expression GUI is shown in Figure 7.

【0068】

Conversational representation 31 is a graphic format (eg, icons, symbols, diagrams, graphs, checkboxes, buttons, other GUI widgets, and sequences and / or combinations thereof), a character format (eg, displayed text, labeling). Input formats, and sequences and / or combinations thereof), and physical formats (eg, buttons, switches, knobs, labels, barcodes, glyphs, braille or other touchable expressions, electronic tags, and It can be in any form that does not require the user to speak out the selection of conversational element 33a, including these sequences and / or combinations).

【0069】

The user examines the conversational expression 31 according to the type of each conversational expression 31 (for example, visually or by touching it) and calls the conversational expression 31 according to the type (type input, point and click, press). , Eye tracking (eye tracking), scanning, etc.) to silently interact with each conversational expression 31.

【0070】

Conversational expression 31 can be presented using one or more display surfaces (eg, computer displays, touch screens, paper, physical devices, etc.) or display formats (eg, pages, frames, screens, etc.). Is. When multiple display surfaces or formats are used, they can be configured in different ways (sequential, hierarchical, graph-based, unordered, etc.) to suit the needs of the user. The user selects one of different display surfaces or formats according to its type (eg, GUI selection, physical operations such as flipping or rotating, button presses, etc.).

【0071】

The user can update the visible conversation element 33a and the associated conversation expression 31 as follows. First, individuals can add new conversational elements and / or related conversational expressions.

【0072】

Second, individuals can remove conversational elements and / or associated conversational expressions.

【0073】

Third, the individual can change the type of conversational expression of the conversational element (eg, text, label, icon).

【0074】

Fourth, the individual can change the conversational representation of the conversational element (eg, text value, label value, icon image) according to its type.

【0075】

Fifth, an individual can modify the conversational elements associated with one or more conversational expressions.

【0076】

Sixth, an individual can add, remove, or change the association between a conversational element and its conversational expression.

【0077】

【0078】

Eighth, the individual can activate the recording and playback function of the selected conversational element.

【0079】

b. Speech data storage device Each conversational element (ie, phrase, word, letter, number, symbol, sound effect, and sequence and / or combination thereof) is suitable for generating audible utterances that can be communicated over the telephone line. Has one or more internal representations. The conversation element 33a stored in the utterance data storage device 33 includes, for example, a sound file format, a recording / playback format, a text, a MIDI sequence, and the like. These internal representations are stored in the utterance data storage device 33 and can be searched from there. In one embodiment, the utterance data storage device 33 is a readable and writable computer memory, as is known in the art. The search can be accessed by random search, sequential search, query search, or other known methods of this type. The data for the retrieved conversational element is passed to the voice generator 34.

【0080】

c. Voice generator The voice generator 34 transforms the internal representation of the conversational element into an audible format suitable for transmission over a telephone connection. In one embodiment, the speech generator 34 is a combination and / or equivalent of a generator that converts text to speech, a sound card, a sound effect generator, and a playback device.

【0081】

d. Voice input A direct voice connection (eg, a microphone) in the user's locale is a switch 37 (eg, a pushbutton switch or other physical switch, a software switch (eg, a GUI widget), an acoustic muffling structure. It can be optionally activated by (eg, a soundproofed housing or other insulating material), and a direct electrical connection (eg, a plug).

【0082】

The recording of voice in the utterance data storage device can be executed by selecting one or more elements from the conversational expression and calling the recording command.

【0083】

e. Audio output The voice output 41 (FIG. 4) makes it possible to generate voice from the utterance data storage device 33 by selecting one or more elements from the conversational expression 31 and calling a playback command.

【0084】

f. Connector that conveys voice to the phone The connection is provided between the user's conversational inputs generated by the switchable voice input 36 or voice generator 34 and delivers a signal suitable for telephone transmission, while the content heard by the local user is Not generated directly. This connection includes direct electrical connections of signals, electronically processed signals such as impedance matching circuits, optical to electrical conversions such as infrared detection, and acoustic signals muted using soundproof housings or other insulating materials. ..

【0085】

FIG. 5 shows an impedance matching circuit 22. Resistor R₁And R₂Is selected to match the input and output signals. Capacitor C₁Eliminates some signal interference (voltage blanking for DC components).

g. Phone-to-user connection A direct voice connection from the phone to the user (ie, earphones) is provided, but the local user does not directly generate audible content. In one embodiment, the phone-to-user connector 30 is an earphone or other topical device that is connected directly to the phone or via some intermediary electronics (eg, a PC and sound card). Speaker system included.

【0087】

h. Upload / Download Data for conversational elements, their displayed conversational representations, and associated internal representations can be found in silent call systems and other silent call systems, external storage devices (eg, compact disks (CDs), Digital video discs (DVD), personal digital assistants (PDA)), directly connected computers, and networked computers (eg, local area networks, wide area networks, the Internet, etc. It can be uploaded and downloaded to and from other systems, including wireless networks). The connection can be provided by a serial connection (RS232, IrDA, Ethernet®, wireless, or other interconnect known in the art). Formatted data (eg, raw byte data, rich text format, hypertext markup language, etc.) is transmitted when the upload command is called from the conversational expression 31 and / or the spoken data storage device 33. (For example, TCP / IP, RS-232 serial data, etc.). When the download command is called, the conversational expression 31 (conversational expression format, speech data storage format) formatted for stored data becomes a component of the appropriate silent call (conversational expression 31, speech data storage device 33). Will be sent.

【0088】

i. Stored data extractor Data for conversational elements, their displayed conversational representations, and associated internal representations can be extracted from the information stored on the host computer. For example, Microsoft's Outlook-formatted calendar entry can be dragged from an application into the form of a stored data extractor 32 that parses and represents the calendar data. In this example, the "promise" object is accessed and its fields (eg, subject, start (time), etc.) are processed. Strings are extracted from the fields and conversational phrases are formatted from these fields and phrase templates. The template takes the form of a predefined text with columns for inserting appropriate data, such as: "The promise of <subject> will start at <start (time)>." The insertion fields <subject> and <start (time)> are provided by characters from the promised object. A speech vocabulary predefined for the generation of speech from the text or for a special purpose can then be used to voice the promised information. Other types of extracted data contain address book entries, database records, spreadsheet cells, email messages, driving instructions, pathnames and information pointers such as global resource locators, and all kinds of information pointers. May contain task-specific information.

【0089】

B. Preparing for silent calls FIG. 4 illustrates the components of an embodiment of a silent call system used to prepare a conversation structure. In this mode, the user, or someone acting on behalf of the user, adds, removes, or modifies conversational structures (expressions, elements, and internal representations) stored within the silent calling system for conversations in silent mode. Prepare.

【0090】

The user looks at conversational expression 31 and makes choices regarding the update of the utterance that should be voiced on the phone (eg, add, modify, delete elements). The utterance data storage device 33 is updated appropriately. The upload / download 40 generates an output signal to the voice output 41, which allows the user to see the stored conversation. The storage data extraction device 32 converts the data stored in another format (for example, a calendar entry of a PC, an address book) into a format suitable for storage in the utterance data storage device 33.

【0091】

III. Silent call method In one embodiment, the silent mode conversation is performed according to the flowchart shown in FIG.

【0092】

As those skilled in the art will understand, Figure 6 illustrates a logical box for performing a particular function. In alternative embodiments, more or fewer logical boxes may be used. In one embodiment of the invention, the logical box alone is a software program, software object, software function, software subroutine, software method, software instance, code fragment, hardware operation or user operation. Or they can be represented in combination.

【0093】

In one embodiment of the invention, the silent call software shown in FIGS. 6 and 15 is stored in a product such as a computer readable medium. For example, silent call software can be a single or combined magnetic hard disk, optical disc, flexible disk, CD-ROM (compact disc read-only memory), RAM (random access memory), ROM (read-only memory). ), Or can be stored in other readable or writable data storage technology.

【0094】

In one alternative embodiment, the silent call software is downloaded using the Hypertext Transfer Protocol (HTTP) to obtain a Java® applet.

【0095】

The incoming call is received by the user, as represented by the elliptical block 60. The user then accepts the call and accesses the conversational expression, as shown in logical block 61. The user then decides whether or not to continue the call, as shown in decision block 62. If the user does not want to continue the call, the call is hung up as shown by logical block 63 and the call is completed as shown by elliptical block 65. If the user wants to continue the call, the user responds by listening to the call and selecting a conversation element from conversational expression 31, as shown in logical block 64. As shown in logical block 66, the internal representation of all conversational elements is retrieved from the utterance data storage device 33.

【0096】

A decision as to whether or not further utterances are selected is made by the individual, as shown in decision block 67. If further speech is needed, the logic moves to logic block 68, where the generated voice of each conversation element is sent to the phone via the connector 35, which conveys the voice to the phone. The logic then returns to decision block 67.

【0097】

The normal telephone process proceeds as shown in the flowchart. Exceptional situations in silent calling methods can occur asynchronously as follows: 1) Whenever the user wants to incorporate live voice into the call, the switchable voice input 36 is used. 2) The user can invalidate the currently playing conversation element by making a new selection from the conversation expression 31. And 3) the user can hang up at any time to end the conversation.

【0098】

FIG. 15 shows a state transition diagram for an embodiment of the silent call of the present invention. Specifically, FIG. 15 illustrates a state transition diagram in which a mechanical device 157 having a left button 157a, a center button 157b, and a right button 157c is used to transition to various states. Buttons 157a-c are conversational expressions for conversational elements. Buttons can represent different conversational expressions in different states. In one embodiment of the present invention, FIG. 15 shows a state transition diagram of the silent call software.

【0099】

There are five states in the illustrated embodiment. That is, there are a telephone standby state 151, a standby state 152 for answering, a moving state 153 for talking, a state of listening to the other party's talk 154, and a call ending state 155, and any state 156 is further shown. The user can change to various states by pressing the buttons 157a to c. As the state changes, an audible message to the user can be generated.

【0100】

For example, the transition from the telephone standby state 151 to the standby state 152 for answering is achieved when an incoming call event occurs. The user then has three options. These options are 1) the user presses button 157a to say nothing, 2) the user presses button 157b to generate the utterance "Please leave a message", or 3 ) The user selects the button 157c on the right to generate an utterance "Please wait a moment because it will come out soon" that only the other party can hear.

【0101】

As can be seen from FIG. 15, embodiments of the present invention allow the user to carry out a conversation without producing audible content around them.

【0102】

IV. Embodiment of silent call In a conversation in silent mode, all participants in the conversation use an electronic device such as a mobile phone. The device may be a wired device or a wireless device. However, a person in a "dissimilar" public place (ie, having to be quiet) will have a special interface for responding to conversations. Below, (1) PC, (2) PDA, (3) scanner and paper interface, (4) telephone accessories with physical button interface, and (5) telecommunications infrastructure with silent call capability. Five different embodiments of, will be described. Other embodiments may include the use of intercom, CB radio, bidirectional radio, shortwave radio, or other radio transmitters such as FM or Bluetooth.

【0103】

A. Implementation by PC An embodiment using a PC system for making a silent call uses a personal computer as a personal "conversation device".

【0104】

In one embodiment using a PC, a GUI template with a conversational expression is stored on the PC. When a user (eg, an individual 17) performs a point-and-click, the computer "talks" to the phone over a voice connection without making any external sound.

【0105】

This is achieved by storing valid conversational phrases pre-recorded in a format suitable for display and user selection. FIG. 7 shows a GUI representation including a conversational representation having an internal representation expressed in the user's own voice. For example, a group of conversation start greeting (Hello) icons 70 are represented by icons 70a to d. The user can pre-record the opening sentence 70a, such as "I'm less. I can hear your voice, but I'm in a quiet place right now, so I can only respond through my computer." Other types of icons and associated statements may be used. For example, the icon of control 71 can include icons 71a to f. The etiquette 72 icon can include icons 72a and b. For example, the icon 72a may be an audible and expressive "please" expressed by the user's voice. The reply icon 73 includes icons 73a to d, and the farewell greeting icon 74 includes icons 74a to c.

【0106】

In one embodiment, Microsoft PowerPoint will use a conversational expression and conversational element, i.e. (1) a graphic structure in which the node contains an audio clip (WAV format), as shown in FIG. 7, and (2) text-to-speech. Is used to form a generator (obtained from an ActiveX component that includes the conversation capabilities of Microsoft's Agent). Microsoft's Agent software includes the ability to convert text to voice. The ability to convert Microsoft Agent text to voice by using standard Microsoft interface definitions (eg ActiveX components) is embedded in PowerPoint slides to convert text for silent calls to voice. Used as a silent call GUI to provide.

【0107】

The template of the conversation, between a group of frequent users, (for example, upload / download and) de be shared as possible (for example, web pages, share files, as an e-mail message). Individuals choose the type of conversation they want to join, and each individual works through a shared template that uses a silent calling interface.

【0108】

FIG. 2 illustrates an embodiment of a silent call PC system. The system 20 includes a PC 21 having a sound card connected to an input jack for mobile phone input.

【0117】

C. Embodiments of a paper user interface In one embodiment of the paper user interface, the conversational expression is printed on paper (eg, a notebook or card), as shown in FIGS. 10, 11 and 12. When the user scans a conversational element associated with a conversational expression (eg, a code) (eg, by a barcode or glyph reader), the computer "speaks" to the phone silently to the outside via a voice connection. ..

【0118】

FIG. 11 illustrates an embodiment of a silent call using a paper user interface. Embodiments of the paper user interface include the PDA 110 and the controller 111. In one embodiment, the controller 111 is used as the utterance data storage device 33, the voice generator 34, and the voice output 41. In one embodiment, controller 111 is a Quadravox QV305 RS232 playback controller. Embodiments of the paper user interface also include upload / download 40 of the QV Pro software commercially available by Quadravox. The controller 111 is connected to a connector 112 that transmits voice to the telephone. In one embodiment, the connector 112 that transmits voice to the telephone is an impedance matching circuit as shown in FIG. Further, the scanner 113 is connected to the controller 111. The scanner 113 is used to read the paper interface 114 containing the code 115.

【0119】

FIG. 12 also shows another embodiment of the paper interface. Paper interface 120 includes code 121 for the conversation expressions such as "Hello / Hello" (i.e., conversational element).

【0120】

In FIG. 11, a scanner 113 (Symbol SPT-1500 barcode scanner, etc.) is used to read conversational elements. In one embodiment, the scanner 113 is connected to the controller 111 via an RS232 port. Each code indicates an audio clip (WAV format) associated with the conversational expression.

【0121】

Controller 111 (eg, Quadravox's QV305 RS232 playback controller) stores audio clips that can be accessed randomly or in sequence. The controller 111 is connected to the telephone input via an impedance matching circuit 112 that allows the voice signal to be directed to the telephone.

The generated conversation can be heard both on the hands-free earphones and over the telephone line, but not in the user's general locale.

【0122】

D. Embodiment of telephone accessory device In one embodiment of the telephone accessory, a physical interface, such as a labeled button, is a conversational expression. The device may be attached to the phone as a phone accessory or may be incorporated into the design of the phone mechanism itself. When the user presses the conversation button, the computer "speaks" to the phone silently to the outside via a voice connection.

【0123】

FIG. 13 shows an embodiment of the telephone accessory device of the present invention. Embodiments of the telephone accessory include a mobile phone 130 connected to a device 131 connected to a connector 132 that transmits voice to the telephone. Device 131 is a physical interface with buttons labeled or marked as their respective conversational representations.

【0124】

In one embodiment of the telephone accessory, the mobile phone 130 is Qualcomm's PDQ Smartphone with a hands-free headset. In one embodiment of the telephone accessory, device 131 is an electronic recording and playback device. In one embodiment, the connector 132 that transmits voice to the telephone is an impedance matching circuit as shown in FIG.

【0125】

In one embodiment, one or more single-channel audio recording and playback chips (eg, Radio shack Recording Keychain) are audio accessible via labeled control buttons. To save. The chip is connected to the telephone input via a connector 132 that conveys voice to the telephone, which allows the voice signal to be directed to the telephone. In one embodiment, the connector 132 that transmits voice to the telephone is R.₁= 10k ohm, R₂= 460 ohms, and C₁It is an impedance matching circuit as shown in Fig. 5 with = 0.1 microfarad. The generated conversation can be heard both on the hands-free earphones and over the telephone line, but not in the user's general locale.

【0126】

The one-chip version can hold a single greeting or multiple greetings that can be used to postpone a conversation until the user moves to a place where the conversation can continue in a normal voice. Other chips may be added for alternative greetings (eg, screening for mobile calls) or limited responses (eg, yes, no, etc.).

【0127】

In an alternative embodiment, a call object is provided. For example, a credit card with silent calling technology (eg, by using the chip placement described above) produces audible utterances (eg, account numbers) silently to the outside. Therefore, personal information will not be heard by others when confirming a reservation or when it is used for other purposes.

【0128】

E. Implementation of telecommunications infrastructure As mentioned above, voice calls are made when at least one of the phones has a non-verbal interface (eg, a button or touch screen). Non-verbal interfaces are used to select and play voice utterances (recorded or synthesized) over a telephone connection. There are many places where voice generation can be introduced in the voice path of a call as shown in FIG. In one embodiment, the call receiver 142 is a mobile phone user who needs to receive an important call, but is not always in a conversational position (eg, conference, public transport). ,waiting room).

【0129】

FIG. 14 shows a telecommunications infrastructure 140 with silent calling technology. The telecommunications infrastructure 140 includes telephone 143 used by telephone caller 141. Telephone 143 accesses telecommunications service provider 146. Telephone 143 selectively accesses the telephone communication server 145 connected to telecommunications service provider 146. In one embodiment, the telecommunications service provider 146 accesses the telecommunications service provider 147, which controls the telephone communication server 148. The telephone communication server 148 then provides a service to the mobile phone 144. All software and / or mechanical devices belonging to the telecommunications infrastructure 140 can be used to implement embodiments of silent communication technology. For example, the silent call software may be run by telecommunications service provider 147. The user can then start speaking by selecting a button on the mobile phone 144.

【0130】

In an alternative embodiment, the silent call software and / or structure described above may be located in other parts of the telecommunications infrastructure 140, such as inside the telephone 144 and / or 143.

【0131】

i. Selection of utterances inside and outside the band There are at least two forms of silent call telecommunications infrastructure implementations. That is, 1) the control signal for utterance selection made by the caller is mixed with voice audio (ie, in-band communication such as touch tone), or 2) the control signal is a voice signal. It is an embodiment that uses a different communication channel (ie, out of band). In either embodiment, a server application capable of generating silent call utterances has access to the telecommunications infrastructure and, as shown in FIG. 14, the voice path of the call (eg, a service. You can operate the provider's telephone server).

【0132】

In-band selection for adding audio audio 16 (a) and 16 (b) illustrate embodiments of an in-band telecommunications infrastructure and silent call servers.

【0133】

If the phone supports text display, a set of possible utterances is displayed on the phone. The text is set on the phone by being pre-obtained from the telecommunications provider (eg, downloaded in a previous voice or data call) or by being acquired or customized during the current call. Communication is a method of calling more attention through a telephone information field such as a caller's ID, or as a touch tone signal, fax tone, or, in a sense, voice (eg, a rhythmic or musical sequence). It can be done via in-band signals such as pushbutton dial signals (Dual-Tone Multi Frequency: "DTMF") for customized signaling technology.

【0134】

If the phone supports dedicated select keys, these can be used to manipulate the selection of conversational elements. When one of the options is selected, an in-band signal sends the message back to the provider with the encoded selection. The selection message is used to access the corresponding conversational element.

【0135】

If the phone does not support the numeric keypad, standard numeric pads (eg, *, 1, 2, etc.) may be used for selection. Relevant DTMF signals from other parties are suppressed by carrier- or provider-specific mechanisms or by temporarily putting the caller on hold while DTMF is being processed. Will be. Alternatively, the telephone may support alternative tone generation (eg, other frequency or rhythmic patterns) that is less audibly disturbing.

【0136】

In one embodiment, the telephone receiver 162 of the telephone receiver has silent call technology for accessing the silent call server 160 and the silent call software 160a, as shown in FIG. 16 (b).

【0137】

In another embodiment, the caller's telephone 161 has a silent call technology for accessing the silent call server 160 and the silent call software 160a, as shown in FIG. 16 (b).

【0138】

In another embodiment, a third party provider is utilized for the call (perhaps by the recipient of the call), as shown in FIG. 16 (a). In this example, a conference call is established and the conversation element selection signals of the recipient of the call (perhaps as DTMF or other audible pattern) are accepted and they are translated into the corresponding audible utterances.

【0139】

Embodiments of various in-band telecommunications infrastructures are described below. First, an embodiment of proxy response on a silent call server can be used. Calls to mobile phones are actually made first by phone number. This can be made easier for the caller (161) to understand by providing the telephone number as the contact point. The silent call server 160 (eg, a telephone communication program, or service provider function) answers an incoming call and dials the recipient's mobile phone 162. When the call receiver (162) answers the mobile phone 162, the connection with the caller (161) is established. The recipient's telephone 162 then immediately connects to the silent call server 160 (eg, via a conference call or as a relay by a server application acting as an intermediary, as shown in FIGS. 16 (a) and 16 (b)). Connecting. The receiver of the call (162) selects an unvoiced call input, which is signaled to the unvoiced call server 160 for decoding and conversion to the appropriate audible utterances. The in-band signal itself, even if audible to the caller (161) (for example, in a continuous three-way conference call connection shown in FIG. 16 (a)), is the caller (as in the conference connection). Even if blocked from 161) (eg, as in the relay connection shown in FIG. 16 (b), or while the control signal is being processed, the caller (161) is temporarily and quickly put on hold. Good (by letting).

【0140】

Second, a third party add-in from a mobile handset can be used in one embodiment. The call is first made directly to the recipient's mobile phone 162. When the call recipient answers the mobile phone 162, a connection with the caller (161) is provided. The telephone immediately connects to the silent call server 160 (eg, by dialing a conference call or relay connection, or by accessing a persistent conference call or relay connection). The generation of in-band signals and utterances is then continued in the same manner as described above.

【0141】

In-band signals require only one communication channel for both voice and data communication, and can function without changing the telecommunications infrastructure (for example, DTMF support is already provided in this system). ), Has the advantage. Under certain circumstances, an audible signal may help some callers to give an audible signal about the situation of the recipient of the call. The disadvantage is that many callers either put up with audible control signals they don't want to hear (eg, by ignoring or camouflaging them) or hide them from the caller. (For example, it is necessary to put the caller on hold during the processing of the control signal). Also, the in-band signal is limited by the amount and speed of control data that can be communicated over the audible channel.

【0142】

b. Out-of-band selection for adding audio audio The selected conversational element can be communicated to the silent call server via some means other than the voice channel of the telephone. FIG. 17 shows embodiment 170 of an out-of-band telecommunications infrastructure. Similar to in-band signals, calls can be made by phone number (surrogate answering technique described above) or directly to the recipient's mobile phone (third party add-in). The silent call server is connected to a voice call via either a conference call or a relay configuration.

【0143】

Embodiments of out-of-band control will be described below.

【0144】

First, related voice and data connection embodiments may be used. Telecommunications systems (such as integrated services digital networks (ISDN)) transmit voice and data on separate channels. For example, telecommunications providers do not send ringing voltage signals to ring people's phones (in-band signals), but providers send digital packets over another channel (out-of-band signals). Calls are processed by a telecommunications service provider by establishing a voice channel and associated control data stream. The control information is transmitted to the silent call server independently of voice communication using an alternative data channel. The silent call server connected to the voice path guides the appropriate utterance as described above.

【0145】

Second, digital communications such as code division multiple access (CDMA) and Internet phones (Voice-over-IP: VoIP) encode voice and data as bits and put packets on digital channels. Simultaneous communication is possible by arranging them alternately.

【0146】

Third, an embodiment of an independent data connection may be used. In one embodiment, the handset comprises an independent data connection, i.e. a second device (eg, a wirelessly connected PDA) to communicate control information between the receiver of the call and the silent call server. There is.

【0147】

Fourth, further embodiments of the telephone connection may be used. The handset may have multiple telephone functions or several telephones may be used. One call conveys control information between the recipient of the call and the silent call server 171. The other telephone 173 has connections with all parties (caller, caller, and server application).

【0148】

Fifth, synthetic or pre-recorded when using a channel that supports simultaneous mixed communication of digital voice and data (eg, VoIP combined with a telephone that can use an IP that acts as a silent telephone). The conversational element can be stored in the telephone handset as a simple data packet. A pre-recorded data set is sent to the caller's digital data stream for the call recipient to capture the voice utterance.

【0149】

Out-of-band signals can be hidden control signals (eg, by temporarily holding the caller on hold), camouflaged (eg, as a rhythmic pattern), or endured (eg, as a rhythmic pattern). , Touch tone) has the advantage of not having to. The disadvantage is that some communication channels require management, except in the case of mixed voice and data packet communications (eg, VoIP).

【0150】

ii. VoIP telecommunications infrastructure VoIP is the ability to make and fax calls over IP-based data networks with good quality of service (QoS) and good profit-to-price ratios. See http://www.protocols.com/papers/voip.htm and http://www.techquide.com. Voice data is encoded in data packets and transmitted using the Internet Protocol.

【0151】

The Parity software (http://www.paritysw.com/products/spt_ip.htm) of Net2phone (http://www.net2phone.com), that is, the "PC with voice software" is the VoIP telephone communication development of the present invention. Provides an application program interface (API) for.

【0152】

In one embodiment of VoIP, information is transmitted over the Internet, telephone exchanges and / or local networks. Figures 18-22 illustrate embodiments of various telecommunications infrastructures that use VoIP capabilities. The embodiments of these infrastructures differ in the location where the voice utterances of the unvoiced call are stored or generated, and whether the telephone used for the dialogue of the unvoiced call is IP capable. Table 1 shows five different configurations for the various infrastructure embodiments shown in Figures 18-22.
