And the radio is transmitted from the antenna 24a to the nearest base station toward the other party. When a response from the other party is received by the antenna 24a from the base station by radio, the received signal is
4 to the communication circuit 34, and further from the communication circuit 34 to the audio output unit 26 (speaker), from which the speaker who puts it to his / her ear can hear the response sound. It has become. When calling the other party, the operation unit 36
A call can be made by pressing the dial number with the key of the other party. However, when the other party's nominal name is registered in the nominal name pattern storage unit (registration unit) 22, the user inputs the nominal name into the voice input unit 12 By speaking toward
It is possible to automatically make a call to the other party by the dial circuit of the communication circuit 34. In this case, the audio signal from the audio input unit 12 is amplified by the amplifier unit 14, converted from an analog signal to a digital signal by an A / D unit 16 (analog / digital converter), and the digital signal is input. The recognized voice recognition unit 18 recognizes the input voice and checks and selects the same name from the nominal names registered in the nominal name pattern storage unit 22. When the voice recognition unit 18 outputs a signal relating to the name to the control unit 20, the control unit 20 selects a dial number registered in the dial number storage unit 38 in advance so as to correspond to the name. By calling the associated dial number and sending it to the dial circuit of the call circuit 34, a call is automatically made. The portable telephone 10 has a recording / reproducing section 40 composed of an IC memory or the like, and can record a voice during a call or in an answering machine mode, and reproduce it later. The portable telephone 10 has a temperature measuring sensor 42. The temperature measuring sensor 42 measures the temperature of the environment and notifies the control unit 20 of the temperature. Can be controlled so as not to deteriorate. The portable telephone 10 has a timer 44.
The clock signal is always output to the control unit 20 to advance the date and time displayed on the display unit 30. In the first embodiment,
As shown in FIG. 2, at the time of the first call, the name of the first candidate and the dial number “XXXXX” are displayed on the display unit 30 by the first recognition by the audio recognition unit 18 and the voice is input. If the name is different from the nominal name (misrecognition), when the second call is made and displayed on the display unit 30 by the second recognition by the voice recognition unit 18, the displayed nominal name and dial number will be the first time. If the same item "OOOO" is to be displayed again as the first candidate, the control unit 20 does not display the name and dial number "OOOO", and the second candidate Control is performed so that the nominal name and the dial number “番号” are displayed. As described above, according to the first embodiment, when the display of the nominal name on the display unit 30 by the recognition of the voice recognition unit 18 at the time of calling is incorrect, the display of the next nominal name is performed after a predetermined time. When displaying a name, a name other than the name displayed in the previous display is displayed, so that the same name as the previous incorrect display is prevented from being displayed every time, and an incorrect name is displayed Since the desired name can be quickly displayed with a reduced number of times, the usability of the voice recognition operating device can be greatly improved. FIG. 3 is a diagram showing a second embodiment of the present invention. In the first embodiment, it is not possible to display the first incorrect name for the third time without displaying the name of the first candidate for the second time. I can't go. Therefore, in the second embodiment,
The control unit 20 (similarity calculating means) calculates the similarity between the voice patterns of the nominal names of the first candidate and the second candidate and the difference between the similarities each time. For example, as shown in FIG. 3, at the first recognition, the similarity of the voice pattern of the nominal name of the first candidate “OOO” is 100, and the nominal name of the second candidate is “Δ”.
Is 95, and the difference in similarity between them is 5. At the time of the n-th recognition, the name of the first candidate “第
The similarity of “Δ” is 97, the similarity of the second candidate nominal name “XXXXX” is 94, and the difference in similarity between them is 3. Then, within a predetermined number of n times If the similarity difference is less than or equal to the specified value (for example, “6”) each time
A warning is displayed on the display unit 30 stating that "Please change either name and re-register". When the user re-registers one of the nominal names, the difference in the voice of the nominal name can be clarified, and the accuracy of recognition can be improved.
