Device and method for remote interrogation of individually stored call numbers

0001The invention relates to an apparatus and a method for remote access individually stored numbers.

0002The modern telecommunication is based on the preparation of compounds allocated between partners, which unique numbers are. Instead of the name of the partner must therefore sequence of digits to Connecting be used. With the introduction of Telecommunication terminals with memories for individual drop phone numbers with a name or special keys, but especially since the introduction of the language choice of name is this Detour for the users made more or less superfluous. Still are the most terminal equipment on the direct selecting Numbers, ie the immediate entry of a sequence of digits, dependent. The user of terminal equipment is thus forced to one or the other kind of numbers to remember. There are a number of resources that simplify the watchlist. The range of such tools ranging from a personal phonebook, on public phone books up to PC-based solutions. Another alternative is the chargeable use of information services.

0003All aids to memorizing numbers, except for the Terminals with voice dial by name, are either fixed or must be available as an additional device with the user. In order to is the freedom of movement for the user terminal equipment in a certain extent limited. Disadvantages are also partly significant costs for special facilities, such as database server or similar .. The same disadvantage relates to the use of Information services.

0004Terminals with voice dial by name feature a technical Basic facilities you choosing without using a phone number the terminal allow itself. However, the use of the Voice dial by name from a distance for the purpose of preparing a Connection not possible.

0005The invention is therefore based on the object to a method and to provide apparatus for remote access from phones available, which is inexpensive and the user the greatest possible distance Flexibility.

0006The object is achieved by a device for remote personalization Stored phone numbers through a telephone network with a speech and Selector and connected thereto speech recognition unit, to identify which predetermined keywords spoken language capable of that in with another, the keyword associated data a memory are stored, said apparatus controlled by a Flow control, depending on the detected keyword data from frees the memory for remote access or a query of where Store the keyword associated data makes, said with the keyword associated data from the memory of the sequencer be passed and the apparatus further comprises a having voice module memory, in which individual data components, such as single digits, assigned language elements in are voice prompts stored, the sequence controller Converting the retrieved data into a voice signal by causes corresponding combination of language elements and the Speech signal through the speech and selecting means over the telephone network is output.

0007The object is further achieved by a method for remote access individually stored numbers over a telephone network, which means a speech recognition unit of a speech input of a remote User names of participants as predetermined, user-defined Keywords are recognized and converted into digital information, with this information associated data, the numbers of the terminal of the subscriber, taken from a local store, in a converted voice signal and the remote user via the telephone network are received acoustically.

0008The user sent voice signal consists of individual Language elements, each corresponding to a digit. Thus, only a minimum storage space for this outgoing message blocks are required.

0009Preferably, the device according to the invention is in a telephone, implemented in particular a telephone with automatic voice dialing by name. This has the advantage that already in the telephone, a speech recognition unit and a memory in which the names of stored participants and associated with them numbers are, is available and can be shared.

0010The apparatus may further be displaced also in the telephone network, including is implemented in the network node or in a switching center. This has the Advantage that the same technical device consisting of Scheduler, voice recognition unit, memory for individual Data and memory for language elements, several participants can be used in common and therefore for the individual is cost-effective. Each participant may be a part of the memory for provided individual numbers-name directory available be, which may establish the subscriber and access.

0011The speech recognition unit is capable of predetermined, partly custom keywords from the spoken language recognize. This can on the one hand commands for controlling the Remote or a personal user code, the other name of be subscribers whose telephone number is to be remotely interrogated.

0012Preferably takes the control flow, the microprocessor a contains an acoustic user guidance means in Voice module memory backed outgoing message blocks before. controlled is it by voice or keyboard inputs from the user.

0013Preferably, the user is first to enter a user code (PIN code) asked which of a PIN storage and comparison unit is analyzed. Is the code entered with an internally in the device, ie in the PIN memory stored code correspond, are the sequence control the interrogation dates. The user can now acoustically enter names of participants, whose number he had informed would like.

0014After entering and converting a spoken keyword in digital information to be associated with this information data retrieved from the memory and transferred to the control flow. The Sequencer then causes the output of the Voice module memory backed individual language elements, the individual Data components associated with such as various items by the talk and selector. So the user is, for example, automatically read the desired phone number.

0015The invention will be explained using an embodiment. 1 shows a block diagram of the apparatus according to the invention, the in a telecommunications terminal, such as a telephone with voice dial by name, is integrated. All components of the terminal, which for Realization of the inventive solution are not needed directly, are shown by dashed lines.

0016The use of the device requires that the the means Terminal application of the individual phone book for voice dialing by name has already taken place. This process is commonly referred to as Training the S pracherkenners referred and from the microphone 6 of the terminal. While the name Training is the for each Names associated phone number either via the keyboard of the terminal or else set by voice recognition. In phone memory 8 are therefore call for the choice of name and Name always stored in pairs before.

0017In the case of a call is the network from coming through the network access 1 Call signal detected in the Rufauswerteschaltung. 3 If the called Participants the call to the terminal as an ordinary working Phone. Otherwise, according to the case of an answering machine After a preset number of rings the connection through the Terminal automatically produced. To distinguish now, whether as desired that the answering system remotely, or a phone number is, the user has the remote subscriber terminal a corresponding Voice command (eg, "answering machine", "remote" etc). This voice command is from the speech recognition unit 9 recognized that over the talk and selector 2 to the access from the network 1 incoming speech signal is coupled. The recognition result provides the speech recognizer 9 to the sequence controller 10, the respective signal paths, in the present case for the remote Number, on.

0018The remote node is performed via a linguistic dialogue whose Elements in the memory for voice prompts are stored 4. The selection of necessary language elements is also by the sequencer 10 made.

0019Before the remote access is allowed, the user must go through the Enter a user code (PIN) identify themselves as authorized. The verification the PIN is the PIN storage and testing device 11. The Result of the check goes to the sequencer 10, which in the negative case further processing of the remote prevented.

0020The actual remote takes place after a call to the remote Visitors linguistic entering the desired name. Of the Speech recognizer 9 recognizes the name, and the recognition result is to retrieve the associated number from the phone memory 8 read for name dialing. This number is for flow control 10 directed that for a conversion of the number found in a speech signal makes. Given that the digits of the number are appropriate read prompts from the memory 4 and and the talk Selector 2 given over the network 1 to the remote user. For more phone queries, the user by voice these Repeat sequence any number of times.
