When the user inputs "J", the registration mode is canceled (step 302).

Next, bank settings are performed (step 303).

Banking is when you register the other party's phone number along with the voice recognition results, you register it in one of multiple registration groups.
When making a call, a registered group is first selected, and a recognition result is searched from among the selected group. For example, it is convenient to improve the recognition rate and shorten the recognition time when shared by multiple users or when used for business and private purposes. The settings for this bank can be set by the user.
It is set by key-inputting "r#J - rlJ or "2"" at 30. Note that "1" and "2" each indicate the number of the registration group described above.

Next, a telephone number is input (step 304).

When entering this phone number, for example, the phone number you want to input or “0”

It is specified by keying in "OJ r6JJ".

As a result, the telephone number "03-254-1111" is stored in the address "06" of the telephone number storage memory 350d of the voice dial section 350.

Next, the audio is registered (step 306).

After specifying the address described above, for example, "Speak" is output from the speaker 492. The voice registration is then performed by the user speaking and inputting, for example, the other party's name "Henry" into the microphone 494.

Next, a beep sound is output from the speaker 492, and “
"Sbeak" is output (step 3o7).

After this, the user again uses the microphone 494 to say “Henry.”
say and input.

As a result, the input voice “Henry°” is input to the voice dial section 3.
At the same time, the input voice "Henry" is recognized by the voice recognition LSI 350b of the voice dial section 350, and the recognition result is stored in the recognition result storage memory 350c as the telephone number. It is stored in association with the number.

Note that by inputting the voice twice as described above, it is possible to obtain the effect of averaging the input voice and improving the voice recognition rate.

Next, the beep sound is output again from the speaker 492, and "NEXT" is displayed on the liquid crystal display 452 for a predetermined period of time.

This "NEXT" asks the user whether or not to register a second phone number (step 308).
.

When registering a second phone number, while "NEXT" is being displayed, the phone number is 03-254-

It is specified by keying in rOJ r7J J''.

Thereby, the second telephone number is stored in the telephone number storage memory 350d in association with the input voice, the recognition result, and the first telephone number.

After the second phone number is entered in this way, or “
If the second telephone number is not input while "NEXT" is displayed, the voice recording part 350's voice recording 1c
The input voice "Henry" recorded in 350a is output from spill power 492, and the telephone number storage memory 3
One or two telephone numbers stored in 50d are displayed on liquid crystal display 452 for a predetermined period of time (step 311).

The user can check whether the input has been made correctly by this output and display.

The registration operation is completed as described above.

Next, the calling operation by voice recognition will be explained based on the flowchart shown in FIG. Note that it is assumed that the bank settings have been made in advance.

First, when the user presses any key on the key section 430 for one second or more, the recognition setting mode is set (step 401).

Next, the voice registered as described above, such as "Henry," is uttered into the microphone 494 (step 402).

Thereby, the voice input from the microphone 494 is sent to the voice recognition JLSI 350b and recognized.

Then, this recognition result is compared with the recognition result stored in the recognition result storage memory 350C.

When the corresponding recognition result is extracted (step 403),
The telephone number associated with this recognition result is extracted from the telephone number storage memory 350d. At this time, if two telephone numbers are associated as described in the registration operation, the first registered telephone number is extracted. and,
This telephone number is displayed on the liquid crystal display 452, and the recording content associated with this recognition result is displayed on the voice recording I.
C 350a and output from the speaker 492 (step 404). This output and display allows the user to confirm that the call is placed correctly.

Note that if this output and display is not what the user intended, it can be canceled (step 40).
5). This cancellation operation is performed by the user pressing any key on the key portion 430 within a predetermined time after the display and output are performed.

If a predetermined period of time elapses without such cancellation, a call is automatically made using the telephone number (step 406).

Thereafter, detection of a paging signal sent from the station side is started (step 407).

Then, it is determined whether the called party is busy (step 408).

The determination as to whether or not a call is busy is made as follows.

The signal sent from the central office during a call is a 1-second dial tone and a ringing tone, as shown in Figure 5(a).
3 seconds of silence are repeated, and when the call is busy, a 174 second beep and l/
There was 4 seconds of silence repeated. The control signal processing unit 338 detects this difference in signals and notifies the CPU 331 of the difference, thereby determining whether or not the call is busy.

When the call is busy, the user can cancel the series of operations by pressing any key on the keys 430 (step 409).

On the other hand, when the call is in progress, a counter for the time 3141 built in the CPU 331 is started (step 4).
10).

While this counter counts out (step 41
1) When the other party goes on-hook and there is no ringing (
Step 412), story a is performed (step 4I3
).

While this counter counts out (step 41
1) When the other party does not go on-hook, the telephone number [1] associated with the above-mentioned recognition result is extracted and displayed on the LCD display 452, and the recorded content associated with this recognition result is extracted. is extracted from the audio recording IC 350a and output from the speaker 492 (step 4I4).

A call is then automatically made using this second telephone number (step 415).

As described above, in this embodiment, two telephone numbers are stored in association with voice recognition results, and when a predetermined time elapses without an incoming call from the first telephone number, the second telephone number is stored in association with the voice recognition result. Since calls are made using the second phone number, even if the person you are calling always has two or more phone numbers set, the call will be made using the voice recognition that corresponds to each phone number. Call functions can be realized with simple operations.

In the above-described embodiment, the present invention was applied to two telephone numbers, but it can of course be applied to three or more telephone numbers.

Further, although the order in which calls are made to the two 7U phone numbers is in the order of registration, the order may be specified by the user's operation. However, when considering operability, it is preferable to use the order of registration.

Furthermore, the present invention can be implemented with the following modifications.

That is, a plurality of telephone numbers are stored in association with one speed dial. When a call operation is performed using the speed dial, one telephone number is selected from among the plurality of telephone numbers and the call is made. At this time, if a predetermined period of time has elapsed without a 6' call being made, a call is automatically made using another telephone number.

〔Effect of the invention〕

As explained above, according to the present invention, a plurality of telephone numbers are stored in association with voice recognition results, and when a predetermined period of time has elapsed without an incoming call in response to the first call, Since calls are made by phone number, even if the person you are calling always has two or more phone numbers, you can easily make calls using voice recognition for each phone number. This can be achieved with simple operations.
