FIG. 9) H Effect of the Invention A Field of Industrial Application This invention relates to a voice dialing telephone device that automatically dials a desired destination in response to voice input.

B. Summary of the invention - In this invention, a voice pattern and a telephone number corresponding to a predetermined voice are stored in a predetermined memory in advance, and when dialing, a voice pattern corresponding to the input voice is stored in the memory in advance. The voice pattern is compared with the pattern, and if a match is found, automatic dialing is performed to the telephone number corresponding to the matched voice pattern.

C. Conventional technology The basic operation of the telephone when making a call is the off-footer of the handset and the subsequent dial operation. 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, a simple button type dial device only makes operation easier, but 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 long distance calls by pressing three buttons, but even with this, three button operations must be performed, and each speed dial It is troublesome to have to remember which destination a number corresponds to. Furthermore, in the case of an automatic dialing device in which a specific key corresponds to a predetermined destination telephone number, only one button operation is required.
Furthermore, if the destination is displayed on each key, there is no need to remember which key corresponds to which destination. 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.

D. Problems to be Solved by the Invention Therefore, it is an object of the present invention to provide a voice dialing telephone device that does not require any key operations to select a destination and can be miniaturized.

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

That is, in the present invention, (a) a memory that stores a voice pattern corresponding to a predetermined voice and a telephone number corresponding to this voice pattern; and (b) a voice pattern that stores an input voice pattern in the memory. and (C) an automatic dialer that automatically dials a telephone number stored in the memory corresponding to the matched voice pattern in response to the detection by the voice recognition means. Make sure you have the means.

F Effect: By performing a predetermined registration operation on the memory, for example, a voice pattern corresponding to a predetermined voice and a telephone number corresponding to the voice pattern are stored in advance.

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 when a match is found, the automatic dialing means calls the telephone number stored in the memory corresponding to the matched voice pattern. Automatic dialing will occur.

As described above, in the present invention, since the destination is selected by voice input, no key operation is required for selecting the destination.

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

G Example G1. 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, an interface circuit 10 performs line switching control for the telephone 1 and voice recognition dialing device 2, on-footer/off-footer detection of the handset 1a of the telephone 1 (FIG. 2), etc., and its internal configuration is shown in FIG. Give an example. This interface 3 circuit 10 includes photocouplers 11, 12 . for on-footer and off-footer detection. It has a configuration including a transformer 13 for signal extraction, buffers 14 and 15, and relay contacts S1+S**Sl+84. Note that S4 is a relay contact for generating a dial pulse signal, and a DC loop is formed in the line 3 between the telephone 1 and the exchanger (not shown). Therefore, both photocouplers 11 and 12 are There is no operation, so the signal arising 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 +5V. Go up. This voltage change at the terminal G is inputted to the CPU 30 via the input/output port 43 (FIG. 1) as an off-footer detection signal. Relay 81 + Sl$S and S4 are input/output boat 4
Switching is controlled by a telephone line control signal sent from the CPU via 3. By the way, this voice dial telephone device has three different station line connection states as shown in Fig. 4(a), (b), and (C), and Table 1 below shows these three station line connection states. The states of relays S1 + St + SS and S according to the line connection state are shown.

Connection status 1 in Table 1 (see FIG. 4(a)) occurs, for example, when manually dialing, during a call after the line is established, or when receiving a call.
Telephone 1 and central office line 3 are directly connected,
The voice recognition dialing device 2 is separated from the central 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 for the central office line 3, and the telephone 1 performs voice recognition dialing. It is circuit-coupled with device 2. Connection state 3 (see FIG. 4(C)) occurs when a call is made using the voice recognition dialing device 2, the telephone 1 is circuit-coupled with the voice recognition dialing device 2, and the voice recognition dialing device It2
is connected to the central office line. Note that when the line is connected as shown in FIGS. 4(b) and (C), if the telephone 1 becomes on-footer (the state in which the handset is placed), the state immediately returns to the state shown in FIG. 4(a). It is supposed to be done.

Now, in Figure 1, the operation panel includes numeric keypad 21.
．． 2-digit 7-segment display n, power switch fZ3.
RCG horn 2A, I, RN button 5, CAN button 26. A SET button n is provided.

The display part n shows the registration number (a number for identifying the registered voice data and the dialed number, which is numbered sequentially from "u" to "Sae") and the telephone number (the dialed number is displayed one digit at a time). etc. will be displayed. Above R, CG
Button Sae, I, RN button 25. A display lamp (not shown) such as a tl or an LED is attached to each of the CAN button and the SET button n, and the display lamp corresponding to the pressed button lights up.几C
The G button is activated when the device is placed in auto-dial mode, as described below. The LRN button 5 is used when putting the device into dialed number registration mode and when manually incrementing the registration number. The CAM button 26 is used to cancel input data during dial number registration, to put the device into a registered content confirmation mode, and to partially change registered content without changing the number of registered words. The SET button n is pressed to fix the number of registered words. The operation panel is connected to the bus BS of the CPU 30 via the buffer driver section and the input/output port 29.
is combined with

Voice data input via the transmitter of the handset 1a 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 by the sample hold circuit, and then sent to the A/D converter 34.
PCM (Pul
se-Cod8Modulation) 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 memo I735 is a non-volatile RAM, and can store voice data of up to U 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 a voice recognition circuit, and after a predetermined voice analysis is performed in the voice recognition circuit 36, it is stored in a voice pattern memory 37 as a voice pattern. The voice pattern memory 37 is a non-volatile RAM, and can store voice patterns up to the highest level by registration number, as shown in FIG. 5(b). In addition to this, the voice recognition circuit also verifies voice data in accordance with instructions from the CPU 30 during auto dial mode.

That is, the voice recognition circuit I recognizes the voice data input through the handset in the auto dial mode, compares the recognized voice pattern with the voice pattern registered in advance in the voice pattern memory 37, The verification result is reported to the CPU 30 via the input/output capo 3B.

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

The telephone number/registered word count memory 42 is a nonvolatile 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 registration word count memo 1J42
In this case, the voice memo 1735° and voice pattern memory 37 described above are stored as "1" to "1" as shown in FIG.
The memory area is divided equally according to the registration number of “A”.
The address of each memory area corresponds to a registration number.

In these memories, the voice memory is used for recording and reproducing voice data, but due to limited storage capacity, one registered word length is defined as the voice up to 1 second after the voice is uttered. Since the voice pattern memory 37 has a smaller capacity than the voice memory 35, it is possible to save 0.2
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 the telephone number/registered word count memory 42, the additional digits of the dial number are set as the maximum length of one registered word.

The input/output port 43 is connected to the interface circuit 10 and receives an off-footer detection signal from the interface circuit 10 indicating that the handset has been removed, 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 the work area γ of the CPU 30
RAM (Random Access Memory) used as

The main operation example of the CPU 30 in such a configuration example is shown in the sixth example.
As shown in the figure.

When the power switch on the operation panel or the top is turned on, the CP
After U30 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 the month (step 100),
The off-footer detection signal input from the interface circuit 10 via the input/output port 43 is monitored (step 1).
01). When the CPU 3Q detects that the handset of the telephone 1 has been picked up by the off-footer detection signal, it then monitors which button on the operation panel has been pressed. Then, when the LfLN button δ is pressed (
Step 102), control is performed by the dial number registration routine (Step 103), and the C and G buttons U
is input (Step 104), control is performed by an auto dial routine (Schip 105), and furthermore, when KCAN Bokun Uta is input (Step 10).
6) Control is performed using a registered data confirmation routine (step 107).

Among the above routines, the dial number registration routine is:
This is a routine for registering arbitrary voice data and dial numbers (both internal and external) in association with each registration number.

The auto-dial routine is a routine for automatically dialing a destination by inputting voice data through the handset of the telephone 1. Further, the registered data confirmation routine is a routine for confirming the registered contents, and when the handset (la) is taken out and the CAN button 2b is pressed, the registered voice data is played back and the dialed numbers are displayed in the order of the registered numbers. In this example of operation, when it is detected that the handset 1a of the telephone 1 is on-hook, the program immediately returns to step 101.

Figure 7 shows the CPU 30 during the dial number registration routine.
An example of a control flowchart 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 After the operator picks up the handset 1a of telephone 1,
Press the LR and N buttons 6 to register the dial number (see Figure 6). When the CPU 30 detects this,
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(a).
At the same time, the registration number "1" is displayed on the display section n of the operation panel weight.
” flashes (step 201), and then monitors whether or not a key is pressed manually (step 202).

Next, the operator inputs the dial number "2316" corresponding to "Totsukyoka" which should be registered in the registration number "1" using the numeric keypad 21 on the operation panel. First, when the dial number "2" is input, it is determined in step 202 that there is manual key power, and the numeric keys are input, so the process goes through steps 204, 205, 206 and 207, and then step 2 is entered.
08, and the input numerical data "2" is stored in the buffer driver section.

Next, enter the dial number "3" and step 20
9, 210, 211, and 207, the process returns to step 208, where the inputted numerical data "3" is stored in the buffer driver 28 following the numerical data "2". The following dial numbers "1" and "6" are similarly stored sequentially in the buffer memory row.

If you press the wrong number key when inputting the dial number, press the CAN button (step 2).
11) Clear the dial number stored in the buffer driver section Step 212) It is possible to re-enter the correct dial number starting from the first digit.

When the operator finishes entering this dial number, the SE
Press T button n. When the input of the SET button is detected (step 210), the CPU sends the input numeric data "2316" from the buffer driver path to the bus BS via the input/output port 29, and outputs the telephone number. -Stored in the storage area corresponding to the registration number "1" in the registered word count memory 42 (see FIG. 5(C))
, the registered dial number is returned to the display section 22 of the operation panel via the input/output capo (input/output capo) 29, and the same dial number is displayed on the display section 22 in order from the first digit (step 213). By looking at this display, the operator can confirm whether the correct dialed number has been registered.

When this display ends, the operator inputs the voice "Totsukyoka" corresponding to the registration number [1] through the handset a of the telephone 1. This voice data is taken into amplifier filters 31 and 32 within the voice recognition dialing device 2. The audio data input to the amplifier filter 31 is sampled and held in the sample hold circuit 33, further converted into a PCM signal by the A-D converter 33, and then transferred to the storage area corresponding to the registration number "1" of the audio memory 35. (See FIG. 5(a)). On the other hand, amplifier 32
The voice data inputted to the voice recognition circuit 36 performs voice recognition, and the recognized voice pattern is recorded as voice pattern memo 1.
) 37 in the storage area corresponding to the registration number "1" (see FIG. 5(b)) (step 214). When the capture of such audio data is completed (step 215)
, the CPU 30 increments the registration number by +1 (step 216). The registration number is the maximum number of registered words (in this case 2
4) (step 217), the display unit 22
The next registration number is displayed blinking (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 321 XXXXJ, the operator will
rOJ rPJ rOJ r6J ra” “2
” ``1'' ...... Enter the numbers in this order.

The rPJ key on the numeric keypad 21 means pause, and the CPU
30, after waiting for the predetermined waiting time, dialing is performed using the registered dial number.

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.

In the same manner, the registration numbers "3", "4", etc.
It is assumed that the registration of voice data and dial numbers corresponding to "Ko" has been completed, and the registration has proceeded until the maximum registration number "u" is displayed and blinking on the display section n (step 201). Thereafter, the dial numbers "3", "5", "5", and "7" are input, and the SET button is pressed (step 210), thereby registering the dial number "24" (step 213), and further The audio data "Uketsuke" is registered. Here, the CPU 30 increments the registration number to "5" (step 216), and searches whether the registration number "6" is less than or equal to the maximum number of registered words "24" (step 217). In this case, the judgment result is “N”
O", the CPU 30 automatically sets the number of registered words to the number obtained by subtracting "1" from the current registration number ("δ" in this case), that is, "24" (step 218).

Setting the number of registered words means setting the number of words to be searched in the auto dialing mode and registered data confirmation mode, which will be described later.In this case, all registered contents from registration numbers "1" to "24" will be searched. Ru. When the number of registered words is set in this manner, the program of the CPU 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 words (24). For example, for registration numbers "1" to "10"
If you want 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 appear on the display part n. Flashing (step 201)
, and then press the SET button n (
Step 205).

By pressing the set button moss, the CPU 30 sets the number of registered words to the number obtained by subtracting "1" from the current registration number (rt1 in this case), that is, "10" (step 219), and then returns the program to the main routine. .

In addition, when resetting the registered contents, the operator can skip the registration number to the desired number by checking that the registration number is flashing and then pressing the LRN button 5 as many times as the number of registration numbers to be skipped ( Step 204)
.

In addition, when resetting the registered contents, if the SET button 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. be done. For example, if the SET button section is pressed in step 205 after the re-registration of five words in the old registration is completed,
The number of registered words is set to five words from registration numbers "1" to "5" (step 219), and the previously registered contents from registration numbers [6] to "10" are ignored from the search target. . In this case, if the SET button n is not pressed in step 205 and the CAN button 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, when the CAM button % is pressed in step 206, the program can be returned to the main routine without changing the number of registered words, and this CAN button 26 is used in combination with the registration number skip function of the I4M button 5 to Used when revising part of the content.

Next, Figure 8 shows the CPU during the auto dial routine.
30 shows an example of a control flowchart.

First, the operator picks up the handset 1a of the telephone 1 and presses the CG button 24 (see FIG. 6).

When the CPj 130 detects this, it sends a telephone line control signal to the interface circuit 10 via the input/output port 43, and changes the line from the state shown in FIG.
At the same time as switching to the state shown in FIG. 3(b), the number of registered words stored in a predetermined area of the telephone number/registered word number memory 42 is read out and inputted to the speech recognition circuit 36 via the input/output capo 38 (step 300). The input number of registered words determines the number of words to be searched between speech recognition circuits.

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
In 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), and the corresponding Verification results are sent to the CP via input/output port 3B.
030 (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 the registration number is reported as a verification result, the CPU 30 outputs the voice memo IJ.
The audio data (PCM signal) corresponding to the registration number is read out from 35 and input to the DA converter 39. D
-A converter 39 converts the input PCM signal into an analog signal, and supplies the converted analog signal to the handset of telephone 1 via filter 40 and amplifier 41 (
Step 303).

The operator listens to 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 you input are played, turn on the handset and press the RCG button 27.
Wait for the lamp attached to step 1 to go out, and then perform 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 notifies the operator of this by displaying a defective code on the display section, for example.

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 Shu 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 controlled as shown in FIG.
) to the state shown in FIG. 4 (al), and the voice recognition dialing device 2 is disconnected from the office line. Once the line with the other party is established, the operator then makes a call as usual, and when the call ends, the operator disconnects the voice recognition dialing device 2 from the office line. , just 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 equal to the external line connection time of the exchange, and sends a dial pulse.

G1. Registered Content Confirmation Mode FIG. 9 shows an example of a control flowchart of the CPU 30 during the registered data confirmation routine.

After picking up the handset 1a, the operator presses the CAN button (see FIG. 6). When the CPU detects this, it sends a telephone line control signal to the interface circuit 10 via the input/output port 43, changing the line from the state shown in FIG. 4(a) to the state shown in FIG. 4 rb). At the same time, the number of registered words stored in the telephone number/registered word number memory 42 is read to recognize the number of words to be searched in this mode.

In this case, it is assumed that the number of registered words is 10 words with registration numbers "1" to "10". First, the CPU 30 has the registration number “
1" is displayed on the display section (step 400; does not blink), and at the same time, the registered audio data corresponding to the audio memory okara registration number "1" is read out, and this is sent to the D-A converter 3.
9, the signal is reproduced to the receiver via the filter 40 and amplifier 41 (step 401).

Next, the CPU 30 reads the dial number corresponding to the registration number "1" from the telephone number/registered word count memory 42, inputs it to the display section via the input/output port 4 and the buffer driver row, are sequentially displayed one digit at a time (step 402). Next, the CPU 30 increments the registration number by +1 (step 404), displays the registration number "2" on the display section η, and then repeats the same operation as described above up to the registration number "10". It should be noted that if the operator hangs up the handset midway through the call, the confirmation of the registered contents is terminated at that point.

In this way, in this embodiment, the dial number registration mode,
An automatic dialing mode and a registered data confirmation mode have been established to realize automatic dialing using 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.

In the above embodiment, one button is provided with multiple functions depending on the operation stage, such as canceling input numerical data when registering the CAN button or setting the device to registered content confirmation mode. , separate buttons may be provided to designate each of these functions, or furthermore, one button may be provided with more types of functions to reduce the number of buttons.

In addition, in the above embodiment, a two-digit display section is provided and the dial number is displayed one digit at a time, but the display section is not limited to this and can display all digits of the dial number at once. You may also use it. Furthermore, the number of registered words is not limited to different words, but any maximum number of registered words may be adopted, and the registration numbers to be displayed are sequentially rOJ, rlJ, starting from "0".
, r2J... may be displayed.

In addition, at each point 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. Then, the registrant may be notified that the voice recognition has been completed. Furthermore, in the above embodiment, when registering, the 8ET button n was pressed every time the registration number was updated by one (step 210 in FIG. 7), but this SET button operation was abolished, and the dial It is also possible to register numbers and voice data, and furthermore, it is possible to first register a plurality of dialed numbers and, after the registration is completed, to register a plurality of voice data corresponding to the plurality of dialed numbers. It is also possible to input the registered data.

Further, in the above embodiment, as shown in FIG. 2, the telephone 1 and the voice recognition dial device 2 are configured in separate casings, but the present invention is not limited to this. It may be constructed in one piece so that the numeric keypad 21 of the operation panel and the dial of the telephone 1 are shared. 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 dial device 2 sends a dial pulse (DP) signal to the line, but a button button (P6) signal consisting of a combination of two voice signals is sent to the line. Of course, it is also possible to transmit the information by

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 memos IJ 35, 37, and 42 is variable. Memory capacity can be reduced by storing data in order from the first address without empty space.

In addition, in preparation for an increase in registered data, a voice memory 35, a voice pattern memory 37, and a phone number/registered word count memory 4 are also provided.
It is also possible to configure 2 to be expandable in advance,
Furthermore, each of these memories is configured with EP-40M, and instead of writing using KCPUGC as in the above embodiment, writing is performed using BP-40M.
The registration data may be written using a ROM writing device.

Furthermore, in the above embodiment, among all the registered data in the voice pattern memory 37, from the registration number "1" to the registration number rn
Although all registered data up to J (n; number of registered words) are searched for by the voice recognition circuit, the manner in which the search targets are selected is arbitrary; for example, registration numbers "1", "5",
It is also easily possible to search for the registration contents corresponding to the skipped registration number, such as "7".

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 should be stored in a separate ROM in advance, and the
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 M. Voice memo I73.5, 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 H, according to the voice dialing telephone device according to the invention, the destination can be selected by voice input,
Because automatic dialing is performed for this destination, no key operations are required to select the destination, making dialing more efficient and contributing to the downsizing of the device. It has excellent effects.
