Abstract

PURPOSE:To discriminate correctness of the result of voice recognition before dialing and prevent erroneous dialing by providing a device that reproduces stored voice in a memory corresponding to conformed voice pattern when coincidence is detected by a voice recognizing device. CONSTITUTION:When a registered number is reported as the result of collation, a CPU30 reads out voice data corresponding to the registered number from a voice memory 35 and inputs it to a D/A converter 39. The converter 39 converts inputted voice data to analog signals and supplies to the receiver of a telephone 1 through a filter 40 and an amplifier 41. An operator hears reproduced voice through a receiver, and when the voice is the same with words inputted by him, waits for completion of automatic dialing. However, when words different from voice inputted by him are reproduced, he sets the handset on, and makes voice inputting or manual dialing waiting until a lamp attached to an RCG button 24 is put off.

Main operation (6th action) G. Dial number registration mode (Fig. 7) G4 Auto dial mode (Fig. 8) H Effects of the invention A. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice dial telephone device that automatically dials a desired destination in response to voice input.

B0 Summary of the Invention In this invention, a predetermined voice, a voice pattern corresponding to the predetermined voice, and a telephone number are stored in a predetermined memory in advance, and when dialing, a pattern corresponding to the input voice is stored in the memory. Compare it with a pre-memorized voice pattern,
If there is a match, the voice stored in the memory corresponding to the matched voice pattern is reproduced to confirm the voice input, and the telephone number corresponding to the matched voice pattern is automatically dialed.

C0 Conventional Technology The basic operation of a telephone when making a call is to take the handset off the hook and then dial.

By the way, this dialing operation requires dialing a 5- to 7-digit number even for a local call, and a 9- or 10-digit number for a long distance call. Conventionally, in order to reduce this dialing operation, dialing devices in the form of pushbuttons, dialing devices with a speed dial function, and even automatic dialing devices in which specific keys are associated with predetermined destination phone numbers have been developed. There is.

However, although the simple button-type dial device is easier to operate, the number of buttons to be operated is still 5 to 10, which is quite large and cumbersome. Also, if a device has a speed dial function, it will be possible to make both local and out-of-town calls by pressing three buttons, but even with this, three buttons must be pressed, and each It is troublesome to have to remember which destination a number corresponds to. Furthermore, with an automatic dialing device in which specific keys correspond to predetermined telephone numbers of the other party, only one button operation is required, and if the number of the other party is displayed on each key, it is easy to know which key corresponds to which telephone number. There is no need to remember what is compatible. However, when this device is adopted, it is necessary to provide keys corresponding to the number of destinations, which has the disadvantage that the device becomes larger.

D0 Problems to be Solved by the Invention Therefore, the present invention seeks to provide a voice dialing telephone device that does not require any key operations for selecting a destination and can be miniaturized.

E. Means for Solving the Problems In the present invention, the destination is selected by voice input, and after the selection result is reproduced by voice, the selected destination is automatically dialed.

That is, in this invention, (a) a memory for storing a predetermined voice, a voice pattern corresponding to this voice, and a telephone number corresponding to this voice pattern, and Φ) an input voice pattern is stored in the memory. (C) when a match is detected by the voice recognition means;
(d) automatically dialing a telephone number stored in the memory corresponding to the matched voice pattern in response to the detection by the voice recognition means; and automatic dialing means.

F. Operation: For example, by performing a predetermined registration operation on the memory, a predetermined voice (for example, a PCM signal), a voice pattern corresponding to the predetermined voice, and a telephone number corresponding to the predetermined voice are stored in advance. put.

During subsequent dialing, the operator inputs the voice corresponding to the desired destination.

The pattern corresponding to the input voice is compared with the voice pattern previously stored in the memory by the voice recognition means, and if they match, the reproduction means reproduces the voice stored in the memory corresponding to the matched voice pattern. After confirming the voice input, the automatic dialing means performs automatic dialing using the telephone number stored in the memory corresponding to the matched voice pattern.

In this way, in this invention, the destination is selected by voice input, so no key operation is required for selecting the destination.Furthermore, since the voice input is confirmed, division dialing can be accurately prevented. be able to.

Hereinafter, embodiments of the present invention will be described in detail according to embodiments shown in the accompanying drawings.

G, Example G8. DESCRIPTION OF THE OVERALL AND CONFIGURATION OF EACH PART FIG. 1 shows an example of the circuit structure of an embodiment of the voice dial telephone device according to the present invention, and FIG. 2 shows an example of its external structure.

This voice dialing telephone device is composed of a telephone 1 and a voice recognition dialing device 2, and the telephone 1 is connected to a central office line 3 via the voice recognition dialing device 2.

In FIG. 1, the interface circuit 10 performs line switching control for the telephone 1 and the voice recognition dialing device 2, on-hook/off-hook detection of the handset (la) (FIG. 2) of the telephone 1, etc., and its internal configuration is shown in FIG. Give an example. This interface circuit 10 has a configuration including photocouplers 11 and 12 for on-footer and off-footer detection, a transformer 13 for signal extraction, buffers 14 and 15, and relay contacts S1 * St p SS * s. . Note that S4 is a relay contact for generating a dial pulse signal. In FIG. 3, when the handset 1 of the telephone 1 is not connected (on-hook), a DC loop is formed in the line 3 between the telephone 1 and the exchanger (not shown). Therefore, both photocouplers 11 and 12 do not operate, but the signal generated from terminal G at this time is at ground level. However, when the handset is picked up (when off-footer), a DC loop is formed in line 3, so either photocoupler 11 or 12 operates depending on the polarity state, and the signal generated from terminal G rises to +5■. Go up.

This voltage change at terminal G is manually inputted to CPU 30 via input/output boat 43 (FIG. 1) as an off-hook detection signal. Relay S1. St, SS, and S4 are switched and controlled by a telephone line control signal sent from the CPU 30 via the input/output port 43. By the way, this voice dial telephone device has three different central office line connection states as shown in Figures 4(a), (b), and (C), and Table 1 below shows these three central office line connections. The states of relays S1°S, , S, and S4 are shown depending on the state.

Connection status 1 in Table 1 (see FIG. 4(a)) occurs, for example, when dialing manually, during a call after establishing a connection, or when receiving a call.
Although the telephone set 1 and the office +1sI3 are not directly connected, the voice recognition dialing device i2 is separated from the office line 3. Connection state 2 (see FIG. 4(b)) occurs, for example, when voice input is performed from the telephone 1 to the voice recognition dialing device 2, and the telephone 1 is in an off-footer state with respect to the central office line 3. 2 is circuit-coupled.

Connection state 3 (see FIG. 4(C)) occurs when a call is made using the voice recognition dialing device ft,2, the telephone 1 is circuit-coupled with the voice recognition dialing device 2, and the voice recognition dialing device Wt2 is connected to the central office It is connected to the line. In addition, when the line is connected as shown in Figure 4(b)'J6 and (C), when the telephone 1 becomes on-footer (the state in which the handset is placed), it immediately changes to the state shown in Figure 4(b)'J6 and (C). It is set to return.

Now, in FIG. 1, the operation panel 20 includes numeric keys 2 and 2.
1. 2-digit 7-segment display 22, power switch 23
, a UCO button 24, an LRN button 25, a CAN button 26, and a SET button 27. Display section 22
Kk! The registration number (a number used to identify the registered voice data and the dialed number, which is numbered consecutively from "1" to "24") and the telephone number (the dialed number is displayed one digit at a time) are displayed. Ru. Each of the above RCG button 24, LR, N button 25, CAN button 26 and SET button 27 traps is equipped with an indicator lamp (not shown) such as 1 LED, and the indicator lamp corresponding to the pressed button lights up. It is supposed to be done. R.C.G.
Button 24 is pressed to place the device in auto-dial mode, as will be described later. , T, RN buttons 25 are used to place the device in dial number registration mode and to manually increment the registration number. C
The AN button 26 is used to cancel input data during dial number registration, and to partially change registered content without changing the number of registered words.

The SET button 27 is pressed to fix the number of registered words. The operation panel 20 is coupled to the path BS of the CPU 30 via a buffer driver 28 and an input/output port 29.

Voice data input via the transmitter of the handset (la) of the telephone 1 is supplied to an amplifier filter 31 and an amplifier 32 via an interface circuit 10. The audio data input to the amplifier filter 31 is sampled and held in a sample hold circuit 33, and then sent to an A/D converter 3.
By performing A-D conversion in step 4, P CM (Pu
lse-CodeModulation) signal. The voice data input during the dial number registration mode is stored in the voice memory 35 after being subjected to the PCM conversion described above.
is entered and stored. The voice memory 35 is a nonvolatile RAM, and can store voice data of up to 24 words by registration number, as shown in FIG. 5(a).

On the other hand, the voice data input to the amplifier 32 is input to the voice recognition circuit 36, where the voice data is subjected to a predetermined voice analysis +bX4, and then stored in the voice pattern memory 37 as a voice pattern.

The voice pattern memory 37 is a non-volatile RAM, and can store voice patterns of up to 24 words by registration number, as shown in FIG. 5(b).

In addition to this, the voice recognition circuit 36 also verifies voice data in accordance with instructions from the CPU 30 during the auto dial mode. That is, the voice recognition circuit 36 opens the voice data input through the handset in the auto dial mode, and combines the recognized voice pattern with the voice pattern memo 1J37 in advance.
The comparison result is reported to the CPU 30 via the input/output port 38.

The D/A converter 39 converts the PCM signal into an analog signal by A-converting the audio data stored in the audio memory 35. This conversion data is filtered by a filter 40,
The signal is applied to the telephone set 1 via the amplifier 41 and the interface circuit 10, and is reproduced as voice via the handset of the handset.

The telephone number/registered word count memory 42 is a non-volatile RAM that stores the set number of registered words as shown in FIG. 5(C), and also stores input dial numbers for each registered number. In addition, this phone number/registered word count memory 42
In this case, the voice memo IJ 35 and voice pattern memory 37 described above are stored as "1" to "1", respectively, as shown in FIG.
The memory area is divided into the same areas according to the registration number of the program, and the address of each memory area corresponds to the registration number. In these memories, the voice memory 35 is used for recording and reproducing voice data, but in order to reduce storage capacity, one registered word length is defined as the voice up to one second after the voice is uttered. The voice pattern memory 37 is the voice memory 35
Since it requires a small capacity compared to
The speech up to 1.5 seconds was defined as one registered word length. In other words, voices of less than 0.2 seconds are treated as noise and are not registered. In addition, in the telephone number/registered word count memory 42, the maximum length of one registered word is 20 digits of the dial number.

The input/output boat 43 is connected to the interface circuit 10 and receives an off-hook detection signal from the interface circuit 10 indicating that the handset has been taken off, and also sends a telephone line control signal output from the CPU 30 to the interface circuit 10. do. 44 in FIG. 1 is a program ROM (read-only) in which a predetermined program for operating the CPU 30 is stored in advance.
45 is a RAM (random access memory) used as a work area for the CPU 30.

G! , main operation An example of the main operation of the CPU 30 in this configuration example is shown in the sixth section.
As shown in the figure.

When the power switch 23 on the operation panel 20 is turned on,
After the CPU 30 performs predetermined initial setting operations such as setting various variables of the program to initial values and setting the registration number displayed on the display unit 22 to "1" (step 100
), interface circuit 1 via input/output port 43
The off-footer detection signal input from 0 is monitored (step 101).

When the CPU 30 detects that the handset of the telephone 1 has been picked up based on the off-footer detection signal, the CPU 30 monitors which button on the operation panel 20 has been pressed.

When the LRN button 25 is pressed (step 102), control is performed using the dial number registration routine (step 103), and when the RCG button 24 is pressed (step 104), control is performed using the auto dial routine. (Step 1o5).

Among the above routines, the dial number registration routine is:
Optional C) Voice data and dial number (for each registration number)
This is a routine for registering an internal line or an external line (both internal and external lines are allowed) in association with each other.

The auto-dial routine is a routine for automatically dialing a destination by inputting voice data through the handset of the telephone 1. In this example of operation, when it is detected that the handset 1a of telephone 1 is on-hook, the program immediately returns to step 101.

Gs, dial number registration mode Figure 7 shows the CPU 30 during the dial number registration routine.
An example of the control flow chart is shown below. Below, an example of operations and operations when registering voice data and dial numbers as shown in Table 2 will be described in detail with reference to FIG.

Table 2 When the CPU 30 detects this, the operator
After picking up the telephone line control signal to the interface circuit 10, the line is switched from the state shown in FIG. 4(a) to the state shown in FIG. The registration number "1" is made to blink on the display section 22 (step 201), and thereafter it is monitored whether or not the key has been pressed manually (step 2).
o2).

Next, the operator uses the numeric keypad 21 on the operation panel 2o to input the dial number r2316J corresponding to "Tokyoka" which should be registered as the registration number "1". First, when the dial number "2" is entered, it is determined in step 202 that the key is present, and a numeric key is entered, so the process goes through steps 204, 205, 206, 207, and step 20.
8, and the input numerical data "2" is stored in the buffer driver 28. Next, when you enter the dial number "3", steps 209, 210, 211, 207
At step 2o8, the input numeric data "3" is stored in the buffer driver 28 following the numeric data "2".

The following dial numbers rlJr6J are also sequentially stored in the buffer memory 28 in the same manner. If you press the wrong number key when inputting the dial number, press the CAN button 26 (step 211) to clear the dial number stored in the buffer driver 28 (step 212) and return the correct dial number. You can re-enter from the first digit.

When the operator finishes entering this dial number, the SE
Press T button 27. When the CPU 30 detects the input of the SET button 270 (step 210), the CPU 30 sends the input numerical data r2316J from the buffer driver 28 to the bus BS via the input/output port 29, and stores it in the telephone number/registered word count memory 42. (See Figure 5(C))
, the registered dial number is returned to the display section 22 of the operation panel 20 via the input/output boat 29 and the buffer driver 28, and the same dial number is displayed on the display section 22 by lighting up in order from the first digit (step 213 ). By looking at this display, the operator can confirm whether the correct dial number has been registered.

When this display ends, the operator inputs the voice "Tokyoka" corresponding to the registration number "1" through the handset (la) of the telephone 1.

This voice data is taken into amplifier filters 31 and 32 within the voice recognition dialing device 2. Amplifier filter 3
The audio data input to 1 is sent to the sample hold circuit 33.
P is sampled and held in the A-D converter 33.
After being converted into a CM signal, the registration number "
1" (see FIG. 5(a)). On the other hand, the same voice data inputted to the amplifier 32 is voice recognized by the voice recognition circuit 36, and the recognized voice pattern is stored in the storage area corresponding to the registration number "1" of the voice pattern memory 37 (see FIG. (b)) (step 214). When the import of such audio data is completed (step 215), the CPU 30 inputs the registration number +
Increment by 1 (step 216). Unless the registration number exceeds the maximum number of registered words (24 in this case) (step 217), the next registration number is displayed blinking on the display section 22 (step 201).

After confirming this blinking, the operator registers the dial number and voice data corresponding to the registration number "2". The operations and operations of each part in this case differ only in that the dialed number is an outside line, and the rest are the same as in the case of the registration number "1" described above. That is, in this embodiment, when connecting to an outside line, first press a predetermined numeric key (for example, "0"), wait for a predetermined waiting time (exchange connection time), and then connect to the outside line. In this case, when registering the dial number r06 321XXXXJ, the operator
OJrPJrOJr6Jr3Jr2JrlJ...
Enter the numbers in this order.

7y key 21(2)r P J key is pause
e), and is used to cause the CPU 30 to wait for the predetermined waiting time and then dial the next registered dial number in the automatic dialing mode.

When the input of the dial number corresponding to the registration number "2" is completed in this manner, the operator inputs and registers the voice (Osaka) corresponding to the registration number "2" in the same manner as described above.

Hereafter, apply the same pressure, registration number r3Jr4J...12
It is assumed that the registration of audio data and dial numbers corresponding to 3JK has been completed, and the registration has proceeded until the maximum registration number "Sae" is displayed and blinking on the display unit 22 (step 201). After that, the dial number "3" r5Jr5Jr7J is input and the SET button 27 is pressed (step 210).
As a result, the dial number with registration number "Sae" is registered (
Step 213 ), and further audio data [Uketsuke-1
is registered. Here, the CPU 30 sets the registration number to "25".
” (step 216),
A search is made to see if the registration number "5" is less than or equal to the maximum number of registered words "Sae" (step 217). In this case, since the judgment result is "NO", the CPU 30 automatically sets the number of registered words to the number obtained by subtracting "1" from the current registration number ("5" in this case), that is, r24J (step 218).
. Setting the number of registered words is to set the number of words to be searched in the auto dialing mode number σM - " °(((), which will be described later. In this case, all registered contents from registration number "1" to "Sae" When the number of registered words is set in this way, the block of CI'U 30 returns from the dial number registration routine to the main routine.

The above is an example of registering data up to the maximum number of registered R (24).
To set the number of registered words to 10 words, do the same as above, and after registering the dial numbers and voice data for registration numbers "1" to "10", the registration number "11" will be displayed on the display section 22. Flashing (step 201
), and then press the SET button 27 (step 205). By pressing the SET button 27, the CPU 30 inputs the current registration number (in this case rl
After setting the number of registered words to the number obtained by subtracting "1" from "1" (step 219), the program returns to the main routine.

In addition, when resetting registration details, etc., to skip the registration number to a desired number, the operator only needs to check that the registration number is flashing, and then press the LRN button 25 to input the number of registration numbers that he or she wants to skip. Step 204
).

Furthermore, when resetting the registered contents, if the SET button 27 is pressed in step 205 after the re-registration of the dial number and voice data is completed, the number of registered words will be revised to the new number of words corresponding to the re-registered registered contents. Do t.

For example, in the old registration, the registration number rlJ to "lO"
The number of registered words is set for the 10 candy up to, and in the new registration KC, the number of registered words is 5! from ``1'' to ``5''! F! After the P+ registration of t is completed, in step 205, press the "S E ]" button 2.
If 7 is input, the number of registered words is set to 5 words from registered fragrance "1" to "5" (step 219),
Previously registered registration contents with registration numbers "6" to "10" are ignored from search targets. In this case, if the S B 1' button 27 is not pressed in step 205 and the CAN button 26 is pressed in step 206, the number of registered words will not be revised.

That is, in this case, 10 words consisting of the new registered contents with registration numbers "1" to "5" and the old registered contents with registration numbers "6" to "10" are searched. in this way,
If the CAM button 26 is pressed in this step 206, the program can be returned to the main routine without changing the number of registered words.
It is used in conjunction with the registration number skip function of the N button 25 to revise a part of the registration contents.

G4. Auto dial mode Next 1 Figure 8 shows the CPU during the auto dial routine.
300 control 70 one chart example is shown.

After picking up 1M from the handset of telephone 1, the operator presses RCG button 24 (see Figure 6). C
When the PU 30 detects this, it transmits the telephone line control signal to the interface circuit 10 via the input/output port 43.
The line is switched from the state shown in FIG. 4(a) to the state shown in FIG. 4(b), and the number of registered words stored in a predetermined area of the telephone number/registered word number memory 42 is read out. is input to the speech recognition circuit 36 via the input/output port 38 (step 300). The number of words to be searched in the speech recognition circuit 36 is determined based on the input number of registered words.

Next, the operator inputs the voice corresponding to the desired destination via the transmitter. This voice data is input to the amplifier 32 in the voice recognition dialing device 2. Voice recognition circuit 3
At step 6, audio data is received from the amplifier 32 in accordance with the audio data input instruction and recognition start instruction from the CPU 30, and the received audio data is recognized. Then, this recognition pattern is sequentially compared with the voice patterns pre-stored in the voice pattern memory 36, from registration number "1" designated by the number of registered words to registration number rnJ (n = number of registered words). The verification results are sent to the CPU 3 via the input/output port 38.
0 (step 301).

This matching result is output in the form of a registration number corresponding to the matched registered voice pattern or in the form of a mismatch. Upon acceptance of the verification result, the CPU 30 confirms the completion of recognition (step 302). Then, when a registration number is reported as a verification result, the CPU 30 reads audio data (PCM signal) corresponding to the registration number from the audio memory 35,
This is input to the D-A converter 39. D-A converter 3
9 converts the input PCM signal into an analog signal, and supplies this converted analog signal to the receiver of telephone 1 via filter 40 and amplifier 41 (step 303).
.

The operator pauses the voice played through the receiver of the handset, and if the voice is the same as the voice he input, he waits for the automatic dialing to end. However, if words different from the voice input are reproduced, the user turns on the handset, waits until the lamp attached to the RCG button 24 goes out, and then performs voice input or manual dialing again. In this way, since the voice recognition results are played back audibly, the operator can determine whether the voice recognition results are correct or not before dialing, thereby preventing incorrect dialing in advance. can.

In addition, if a mismatch is input as the verification result, C
The PU 30 displays a defective code on the display unit 22, for example, and notifies the operator of this.

When the reproduction of the registered voice is completed, the CPU 30 reads out the dial number corresponding to the registration number obtained as the verification result from the telephone number/registered word count memory 42, and
A telephone line control signal is sent to the interface circuit 10 via the input/output port 43, and the line is connected as shown in FIG. 4(b).
The state shown in FIG. 4C is changed to the state shown in FIG. 4C, and a dial pulse signal corresponding to the read dial number is sent to the central office line (step 304). After that, when the CPU 30 detects that the line has been established, it sends the telephone line control signal again to the interface circuit 10 via the input/output port 43, and the line is connected as shown in FIG. 4(C).
The state shown in K is switched to the state shown in FIG. 4(a), and the voice recognition dial device 2 is separated from the central office line. Once the line with the other party is established, the operator can make a call as usual, and when the call ends, the operator can put the handset on-hook.

In addition, in the case of circuit connection from an extension line to an outside line, CPU3
0 detects the P signal in the registered dial number, provides a waiting time for the external line connection time of the exchange, and sends a dial pulse.

In this way, in this embodiment, a dial number registration routine and an auto-dial routine are provided to realize automatic dialing by voice input.

Therefore, the operator can easily perform automatic dialing by simply uttering the same words as the registered voice corresponding to the desired communication party when dialing. Furthermore, when a voice is input during dialing, the result of recognizing the input voice is played back and sent back to the operator, allowing the operator to properly determine whether the recognition result is correct or not.

In the above embodiment, one button is provided with a plurality of functions depending on the operation stage, such as canceling the input numerical data when registering the CAM button 26 or partially changing the registered contents. Separate buttons may be provided to designate each of these functions, or furthermore, a single button may be provided with a greater variety of functions to reduce the number of buttons.

Further, in the above embodiment, a 2#7 display section is provided to display even one digit of the dial number in order, but the display section is not limited to this, and can display all digits of the dial number at once. You may also use Furthermore, the number of registered words is 2
It is sufficient to use the maximum number of registered words for Renryu, not just 4 words, and the registration numbers to be displayed are rOJ, rlJ, rlJ, rOJ, rlJ, etc.
It may be displayed as r2J....

In addition, at each point in time when voice recognition is completed during registration, the display state may be changed, such as changing the display from lit to blinking or changing the display color, or a tone signal (beep) may be output from the telephone. For example, the registrant may be notified that the voice recognition has been completed. Furthermore, in the above embodiment, the SET button 27 was pressed every time the registration number was updated by one (step 210 in FIG. 7), but this SET button operation has been abolished and the automatic pressure It is also possible to register dialed numbers and voice data.Furthermore, it is possible to register multiple dialed numbers first, and after the registration is completed, register multiple voice data corresponding to the multiple dialed numbers. It is also possible to input the registration data by

Further, in the above embodiment, the telephone 1 and the voice recognition dialing device 2 are configured as separate units as shown in FIG. 2, but the present invention is not limited to this. It may be configured in one piece so that the numeric keypad 21 of the operation panel 20 and the dial of the telephone 1 are used in common. Furthermore, by incorporating a microphone and a speaker in the voice recognition dialing device 2, it is possible to easily register and confirm voice data without taking out a handset. Furthermore, in the above embodiment, the voice recognition dialing device 2
Although the dial pulse (T) and P) signals are sent to the line, it is also possible to send a pushbutton (PB) signal consisting of a combination of two audio signals to the line. Of course.

By the way, in the above embodiment, the voice memory 35, the voice pattern memory 37, and the telephone number memory 42 each have the same storage area divided by registration number, but the data length of each of these memories 35, 37, and 42 is By making it variable and storing it sequentially from the first address without empty space, the memory capacity can be reduced.

However, in preparation for an increase in registered data, it is also possible to configure the voice memory 35, voice pattern memo 1J37, 1 (and telephone number/registered word count memory 42) so that they can be expanded in advance, and furthermore, each of these memories can be expanded. It is configured with BP-40M, and the writing is not done by KCPU as in the above embodiment, but by EP.
-) Pressure may be applied to write the registration data by the tOM Toyogome heavy equipment.

Furthermore, in the above embodiment, among all the registered data in the voice pattern memory 37°, the registration numbers ``1'' to ``nJ''
All registered data up to (n: number of registered words) are set as search targets for the voice recognition recall 36, but the manner in which the search targets are selected is arbitrary. For example, registration numbers rlJ, r5J
, r7J, etc., it is easily possible to search for the registration contents corresponding to the skipped registration number.

In addition, if there is essential registration data that makes re-registration impossible, the dial number, voice pattern, and voice corresponding to the essential registration data are stored in a separate ROM in advance, and the 1'
The configuration may be such that registration data that can be re-registered and input by the operator is stored in a RAM provided separately from the tOM. voice memory 35, voice pattern memory 37,
If the telephone number/registered word count memory 42 is entirely composed of ROM, registration of dialed numbers and voices becomes unnecessary.

As described in detail of the invention H0, according to the voice dial telephone device according to the invention K, the destination is selected by voice input and automatic dialing is performed for the destination. No key operations are required for selection, allowing efficient dialing and downsizing of the device. Furthermore, since the recognition verification result of the voice input during dialing is played back for the operator to confirm, the operator can accurately determine whether the recognition verification result is correct or not, thereby ensuring reliable dialing. All you can do is prevent it.
