Then, if the alphanumeric characters set and displayed in the input item section 14a match the desired address, the microphone 3 is used to input "OK" by voice (step ST29). As a result, the main processing unit 1 recognizes that the URL input based on the recognition data of the voice recognition unit 6 is correct, accesses the URL set and displayed in the input item unit 14a, and displays the image information of the corresponding homepage. It can be viewed on a browser (step ST30).

【0064】

Here, in advance, co.jp "company" or "coojp", which is frequently used as a homepage URL, .com "dotcom", ne.jp "neje", etc. are registered in the dedicated dictionary of the storage unit 7. By setting these keywords, multiple alphanumeric characters can be set and displayed by one voice input.

【0065】

Further, in the above-mentioned URL voice recognition standby state (step ST26), the URL is set and input character by character, but the URL of the desired homepage address is registered in the storage unit 7 in advance and read out when the setting is input. You can also enter the settings. At this time, in the URL voice recognition standby state (step ST26), the URL registered by the main processing unit 1 is read from the storage unit 7 by inputting the keyword "UR Eltouroku" by voice, and the URL is set and input to the input item unit 14a. To do. Multiple URLs to be registered in the storage unit 7 can be registered for each homepage, etc., and multiple URLs registered by voice input of the keyword "UR El Touroku" can be displayed in a list and configured to be selectable, or individual URLs can be registered individually. Each registration keyword may be set. This makes it easy to set and enter the URL.

【0066】

When ending the homepage browsing (step ST31, Yes), by voice inputting the keyword "Owari" from the microphone 3 and turning off the TALK switch 17 (step ST32), the main processing unit 1 terminates the browser and becomes the provider. Disconnect the line connection and end the "voice input mode" (step ST33).

【0067】

(E-mail transmission control) Next, FIGS. 7 and 8 are flowcharts showing the control operation of e-mail transmission. When sending an e-mail, the user turns on the TALK switch 17 (step ST23) and voice-inputs "mail toroku" from the microphone 3 (step ST35). As a result, the main processing unit 1 enters the voice recognition standby state of the mail address based on the post-recognition data output from the voice recognition unit 6, and displays and outputs the mail transmission input screen to the display device 14 (step ST37).

【0068】

FIG. 9 is a diagram showing an input screen for sending an e-mail. As shown in the figure, at the time of this activation, the standard parts (@ and the first and second input item parts 14b and 14c before and after @, respectively) required as an e-mail address are set in advance on the screen. Then, the cursor 14ba indicating the input position of alphanumeric characters (alphanumeric characters and numbers) is displayed in the first input item unit 14b.

【0069】

Next, the alphanumeric characters corresponding to the first input item part 14b of the other party's e-mail address are input by voice from the microphone 3. The main processing unit 1 recognizes the alphanumeric characters input by voice based on the recognized data, and sets and displays each character in order from the position of the cursor 14ba in the first input item unit 14b (step ST38).

【0070】

If there is an error in the alphanumeric characters set and displayed in the first input item section 14b (step ST39, No), the keyword "Yarinaoshi" is input by voice from the microphone 3 (step ST52). At this time, the main processing unit 1 recognizes that it is NG based on the recognized data, returns to (step ST37) again, and sets the input state of the input item unit 14b of the display device 14.

【0071】

Then, if the alphanumeric characters set and displayed in the first input item section 14b match the desired e-mail address, the keyword "tsugi" is input by voice from the microphone 3 (step ST40). As a result, the main processing unit 1 recognizes that the e-mail address input to the first input item unit 14b is correct based on the recognized data of the voice recognition unit 6, and moves the cursor 14ca to the next second input item unit 14c. Display guidance (step ST42, No, step ST41). The user inputs the alphanumeric characters of the corresponding address of the other party's e-mail address into the second input item part 14c by voice in the same procedure as above (step ST37 to step ST39), and corrects if necessary. (Step ST52), perform a voice input operation so that the alphanumeric characters set and displayed in the second input item section 14c match the desired address.

【0072】

At the time of inputting this e-mail address, the above-mentioned dedicated dictionary is selected and activated, and the e-mail address can be easily set and input by one voice input using "CooJP", "dotcom" and the like. In addition, it is also possible to set and input an e-mail address corresponding to the keyword by using a desired e-mail address input keyword (corresponding name, etc.).

【0073】

Then, after confirming that the e-mail addresses displayed in the first and second input item sections 14b and 14c match the e-mail address of the other party, the keyword "tsugi" is input by voice (step ST40). The main processing unit 1 determines that the input of the e-mail address is completed based on the state in which the second input item unit 14c is set and input (step ST42, Yes).

【0074】

After that, the cursor 14da is guided and displayed on the input item section 14d of the mail subject of the display device 14, and the mail subject voice recognition standby state is set (step ST43). Then, when the user inputs the subject by voice from the microphone 3, the main processing unit 1 displays the mail subject in the input item unit 14d based on the recognized data of the voice recognition unit 6 (step ST44). The main processing unit 1 does not select the above-mentioned dedicated dictionary when inputting this subject and the mail body described later, and prevents erroneous recognition by voice input of a normal sentence.

【0075】

If the email subject displayed in the input item section 14d is different from the desired subject (step ST45, No), the keyword "Yarinaoshi" is input by voice from the microphone 3 (step ST53). As a result, the main processing unit 1 recognizes that it is NG, and again sets the input state of the mail subject input unit 14d of the display device 14 (return to step ST43).

【0076】

If the email subject displayed in the input item section 14d matches the desired subject (step ST45, Yes), the keyword "tsugi" is input (step ST46). As a result, the main processing unit 1 recognizes that the mail subjects match, and then guides the cursor 14ea to the input item part 14e of the mail body of the display device 14 to display the voice recognition standby state of the mail body. (Step ST47).

【0077】

By inputting the text from the microphone 3 here, the user recognizes the text via the voice recognition unit 6, and sets and displays the recognized characters in the input item section 14e of the mail body of the display device 14. (Step ST48). When the text displayed after recognition needs to be corrected (step ST49, No), the user inputs the keyword "Yarinaoshi" by voice from the microphone 3 (step ST54). As a result, the main processing unit 1 recognizes that it is NG, and again sets the input state of the input item unit 14d of the mail body (return to step ST47). When correcting characters, the cursor 14ea can be moved by voice input such as the keywords "Susumu" and "Moddle" to correct the characters on the moving position.

【0078】

Then, if the user confirms that the content of the text displayed in the input item section 14e of the email text is correct (step ST49, Yes), then the user inputs the keyword "Soushin" from the microphone 3 by voice and presses the TALK switch 17. Turn it off (step ST50). The main processing unit 1 determines that the transmission is based on the data after recognition, and sends an e-mail with the input contents to each input item unit 14b, 14c, 14d, 14e of the address, subject, and body to connect with the provider. Disconnect (step ST51) and end the "voice input mode".

【0079】

By the way, in the e-mail reception operation, the user can easily execute the e-mail reception process by turning on the TALK switch 17 in (step ST23) and inputting "mail jushin" by voice from the microphone 3 (step ST35). After that, by turning off the TALK switch 17, the "voice input mode" is terminated and the connection with the provider is disconnected (step ST51).

【0080】

The homepage browsing by voice recognition and the e-mail transmission / reception function in the second embodiment described above are not limited to activating each independently, but are during a call of the mobile phone device 15 (step ST9 described in FIG. 2). By turning on the TALK switch 17, the voice input from the microphone 3 can be transferred from the call to the voice recognition. When browsing the homepage and sending / receiving e-mail using the communication line of the mobile phone device 15, the call is temporarily disconnected, and the line is reconnected after browsing the homepage and sending / receiving the e-mail.
