[Detailed description of the invention] The present invention will be explained in the following order.

A. Field of industrial application B. Overview of the invention C. Prior art D. Problem to be solved by the invention E. Means for solving the problem (Fig. 1) (Figures 1 to 5) G. Main operation (Figure 6) G3 Dial number registration mode (Figure 7) G4 Auto dial mode (Figure 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 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 prestored in the memory. and when there is a match, the telephone number corresponding to the matched voice pattern is automatically dialed, and a memory for storing the voice pattern and the telephone number is formed into a unit and configured to be detachable from the device.

C1 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 a simple button type dial device is easy to operate, the number of buttons to be operated is 5 to 10, which is quite large and cumbersome.

Also, if it has a speed dial function, for example, 3
Both local and long-distance calls can be made by pressing three buttons, but this still requires pressing three buttons and remembering which destination each abbreviated number corresponds to. It is necessary and troublesome. Furthermore, in the case of an automatic dialing device in which specific keys correspond to predetermined destination numbers, only one button operation is required, and if the destination is displayed on each key, it is easy to see which key corresponds to which destination. There is no need to remember what to do. 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 aims to provide a voice dialing telephone device that does not require any key operations for selecting a destination and can be miniaturized.

Means for Solving the E0 Problem In the present invention, the destination is selected by voice input, and the selected destination is automatically dialed.

That is, in this invention, - a memory that stores a voice pattern corresponding to a predetermined voice and a predetermined telephone number corresponding to the voice pattern; - a voice that stores the input voice pattern in the memory; voice recognition means that matches a pattern and detects it if it matches; automatic dialing means that automatically dials a telephone number stored in the memory that corresponds to the matched voice pattern in response to the detection by the voice recognition means; and the memory is formed into a unit, and the memory unit is configured to be detachable from the main body of the apparatus.

20 Effect After the memory unit is installed in the device, a voice pattern corresponding to a predetermined voice and a telephone number corresponding to the voice pattern are stored in advance by, for example, performing a predetermined registration operation on the memory in the memory unit. I'll let you.

During subsequent dialing, the operator installs the memory unit in which the desired destination is pre-stored into the device, and then
Input the voice corresponding to the desired destination.

The pattern corresponding to the input voice is compared with the voice pattern pre-stored in the memory in the memory unit by the voice recognition means, and if they match, the automatic dialing means is used to check the voice pattern in the memory corresponding to the matched voice pattern. Automatic dialing with a stored phone number 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. In addition, since the memory is made into a unit and can be detached from the main body of the device, it is possible to prepare multiple memory units to correspond to multiple speakers or groups, so that the memory can be configured to meet the needs of each speaker. Automatic dialing can be easily achieved.

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 CONFIGURATION OF THE WHOLE AND EACH PART FIG. 1 shows an example of the external structure of an embodiment of the voice dial telephone device according to the present invention, and FIG. 2 shows an example of its internal structure.

This voice dial telephone device is composed of a telephone 1 and a voice recognition dial group gt2, and the telephone 1 is connected to a central office line 3 via the voice recognition dial device '2.

In FIG. 2, the interface circuit 10 performs line switching control for the telephone 1 and the voice recognition dialing device 2, and controls the on-footer and handset 1a of the telephone 1 (FIG. 1).
It performs off-hook detection, etc., and an example of its internal configuration is shown in FIG. This interface circuit 10 includes photocouplers 11 and 12 for on-hook and off-hook detection, a transformer 13 for signal extraction, buffers 14 and 15, and relay contacts SI, S2 . S3. S4. Note that S is a relay contact for the dial pulse signal generation phase. In FIG. 3, when handset 1-1a of telephone 1 is not connected (on-hook), a DC loop is formed in line 3 between telephone 1 and an exchanger (not shown). , Therefore, both photocouplers 11 and 12 do not operate, and therefore the signal generated from terminal G at this time is at ground level. However, when the handset is picked up (off-hook), a DC loop is formed in the signal 3, so either photocouplers 11 and 12 operate depending on the polarity state, and the signal generated from terminal G becomes +5■. stand up This voltage change at terminal G is used as an off-footer detection signal by the input/output board 40 (
2) to the CPU 30. relay"'
I e J+ S3 t and S4 are input and output capo) 40
Switching is controlled by a telephone line control signal sent from the CPU 30 via the telephone line control signal. 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 S, , S, , S, and S4 are shown depending on the state.

Connection status 1 in Table 1 (see Figure 4 (a)) occurs, for example, when manually dialing, during a call after the line is established, or when a call is received, and the telephone 1 and the office line 3 are not directly connected. However, the voice recognition dialing device 2 is separated from the central office line 3. Connection state 2 (see FIG. 4 (bl)) 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 voice recognition dialing device 2 for station a3. Connection state 3 (see FIG. 4(C)) occurs when the voice recognition dialing device 2 is used to make a call, and the telephone 1 is circuit-coupled with the voice recognition dialing device 2, and the voice recognition dialing device 2 is connected in a circuit. The device 2 is connected to the central office line.In addition, when the line is connected as shown in FIGS. 4(b) and (C), the telephone 1
When the handset goes on-hook (the handset is disconnected), it immediately returns to the state shown in FIG. 4(a).

Now, in FIGS. 1 and 2, the operation panel 20 includes a numeric keypad 21, a two-digit 7-segment display 22, a power switch 23, an RCGC tabos, an LRN button 25,
A CAN button 26 and a SET button 27 are provided. The display unit 22 displays a registration number (a number for identifying the registered voice data and dialed number, which is numbered consecutively from "1" to "24") and a telephone number (the dialed number is displayed one digit at a time). ) etc. are displayed. Above RCG button 24, LRN button 25, CAN button 2
6 and the SET button 27 are each provided with a display lamp h such as an LED, and the display lamp corresponding to the pressed button lights up. R, C.G.
Button 24 is pressed to place the device in auto-dial mode, as will be described later. The LRN button 25 is used when placing the device in dialed number registration mode and when manually incrementing the registration number.

The CAN 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 bus 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 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 in a sample hold circuit 33, and then
/D converter 34 performs A-D conversion to convert the PC.
M (Pulse-Code Modulation
) is converted into a signal. After the voice data input during the dial number registration mode is converted to PCM,
Audio memory 51 of memory unit 50 via bus BS
is entered and stored.

On the other hand, the voice data input to the amplifier 32 is input to the voice recognition circuit 35. The speech recognition circuit 35 applies a predetermined speech analysis to the input speech, and inputs the analysis result to the speech pattern memory 52 of the memory unit 50 via the input/output port 36. In addition to the above-mentioned voice analysis, the voice recognition circuit 35 also performs voice data verification according to instructions from the CPU 30 in the auto dial mode. That is, the voice recognition circuit 35
In the auto dial mode, the voice data input through the handset is recognized, the recognized voice pattern is compared with the voice pattern registered in advance in the voice pattern memory 52, and the result of the comparison is sent to the input/output port. CPU via 36
Report on 30th.

The D/A converter 37 converts the PCM signal into an analog signal by D/A converting the audio data read from the audio memory 51. This converted data is applied to the telephone set 1 via the filter 38, amplifier 39 and interface circuit 10, and is reproduced into voice via the receiver of the handset 1a.

The input/output board 40 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.

Next, the memory unit 50 has a structure in which a board on which a non-volatile RAM and other necessary accessory circuits are mounted is housed in an appropriate box-shaped case 55, and the circuits on these boards are connected to male contacts 56. It is connected to the. Each memory 51, 52, 53, and 54 in this memory unit 50 is backed up by a battery 57. On the other hand, a female contact 5 is provided at a predetermined position on the top surface of the voice recognition dial device 2.
8 is provided, and this female contact 58 is connected to each circuit (
(excluding the memory unit 50). Therefore, the memory unit 50 is inserted into the insertion slot 59.
If the connector is connected to the memory unit 50, the voice memory 51, voice pattern memory 52, telephone number memory 5
3. The registered word count memory 54 and other auxiliary circuits can be electrically connected to each circuit in the voice recognition dialing device tZ.

Audio memory 51 in this removable memory unit 50
is a non-volatile RAM, and can store audio data of up to 24 words 4 for each registration number, as shown in FIG. 5(a). This voice memory 51 is used for recording and reproducing voice data, but in order to reduce the storage capacity, one registered word length is defined as a voice up to 1 second after the voice is uttered. Next, the voice pattern memory 52 is a nonvolatile RAM,
As shown in FIG. 5(b), up to 24 words of speech patterns recognized by the speech recognition circuit 35 can be stored for each registration number. Since the voice pattern memory 52 has a smaller capacity than the voice memory 51, one registered word length is a voice of 0.2 to 1.5 seconds after the voice is uttered. 0
．． Voices lasting less than 2 seconds are treated as noise and are not registered. Furthermore,
The telephone number memory 53 is nonvolatile H, AM, and the fifth
As shown in Figure (C), the input dial numbers are stored for each registration number. In this memory 53, the maximum length of one dialed word is 20 digits of the dial number. The number of registered words set in the dial number registration mode is stored in the registered word number memory 54.

Note that these voice memory 51 and voice pattern memory 52
In this case, the telephone number memory 53 has a memory area divided equally according to the registration numbers "1" to "24" as shown in FIG. 5, and the address of each memory area corresponds to the registration number. ing.

In FIG. 2, 41 is a program ROM in which a predetermined program for operating the CPU 30 is pre-stored, and 42 is an RA used as a work area for the CPU 30.
It is M.

G1. Main Operation An example of the main operation of CP[J30 in the configuration f1i is shown in FIG.

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
), the interface circuit 10 via the input/output port 40
The off-footer detection signal input from the controller 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. Then, when the LRN button 25 is pressed (step 102), it is controlled by the dial number registration mode (step 103), and the RCG
If the button 24 is pressed (step 104), control is performed in auto dial mode (step 10).
5).

Among the above-mentioned modes, the dial number registration mode is a mode for registering arbitrary voice data and dial numbers (both internal and external) in association with each other for each registration number.

Further, the auto dial mode is a mode in which automatic dialing is performed to 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 of telephone 1 is on-hook, the program immediately returns to step 101.

G.6 Dial Number Registration Mode FIG. 7 shows an example of a control flowchart of the CPU 30 in the dial number registration mode. Below, according to FIG. 7, operations and operations when registering voice data and dial numbers as shown in Table 2 are shown in Table 2. First, the operator inserts the memory unit 50 into the insertion slot 59 of the voice recognition dialing device 2. . 0.Next, input a telephone line control signal through the operator card 40 to make the registration number "1" flash (step 201), and then monitor whether or not the key has been pressed manually (step 202).
).

Next, the operator presses the numeric keypad 21 on the operation panel 20.
Enter the dial number r2316J corresponding to "Tokyoka" to be registered in the registration number "1". First, when the dial number "2" is entered, it is determined in step 202 that there is manual key power, and the number keys are entered, so the process goes through steps 204, 205, 206, 207, and step 2.
08, and the input numerical data "2" is stored in the buffer driver 28. Next, enter the dial number "3" and step 209, 210 ° 211, 207
Step 208 is then reached again, and the input numeric data "3" is transferred to the buffer driver 28 as the numeric data "2".
” and then memorized.

The following dial number rlJr6J is also stored in the multiple buffer memory 28 in the same manner. If you press the wrong number key when inputting the dial number, press the CAN button 26 and the judgment in step 211 will be rYB.
s J. Therefore, after clearing the input dial number of buffer driver 28 in step 212 (step 212), the correct dial number is input again starting from the first digit.

When the operator finishes entering this dial number, the SE
Press T button 27. When the input of the SET button 27 is detected, the CPU 30 inputs the input numerical data r2.
316J is sent onto the bus BS via the buffer driver 28 and the input/output boat 29, and then stored in the storage area corresponding to the registration number "1" of the telephone number memory 53 in the memory unit 50 ( 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 from the first digit. The order number is displayed by lighting (step 213). By viewing this display, the operator can confirm whether the correct dial number has been registered.

When this display ends, the operator inputs the voice "Totsukiyoka" corresponding to the registration number "1" through the handset of the telephone 1. This voice data is taken into the amplifier filters 31 and 32 in the voice recognition dialing device 2 (step 214). The audio data input to the amplifier filter 31 is sampled and held by the sample hold circuit 33, and further converted into a PCM signal by the A-D converter 34, and then stored in the registration number "1" of the audio memory 51 in the memory unit 50. The data is stored in the corresponding storage area (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 35, and the recognized voice pattern is transferred to the voice pattern memory 52 in the memory unit 50 via the input/output port 36 with the registration number "
1" (see FIG. 5(b)). When the import of such audio data is completed (step 215), the CPU 30 increments the registration number by +1, and displays it on the display unit 22 unless the registration number exceeds the maximum number of registered words (in this case U) (step 217). The registration number is incremented by +1 while 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 device, when connecting to an outside line, press a predetermined numeric key (for example, r OJ), wait for a predetermined waiting time (exchange connection time), and then connect the telephone to the outside line. In this case, when registering the dial number r06 321 XXXXJ, the operator
Numbers are entered in the order of JrPJrOJr6Jr3Jr3JrlJ... The rPJ key on the numeric keypad 21 means pause, 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 auto dialing mode. .

When the input of the dial number corresponding to the registration number "2" is completed in this way, the operator dials the number and inputs the voice "Osaka" corresponding to the registration number "2" in the same way as described above.
register.

Thereafter, in the same manner, registration number r3Jr4J..."Ru"
It is assumed that the registration of voice data and dial numbers corresponding to each of has been completed, and the registration has proceeded until the maximum registration number "tsu" is displayed and blinking on the display unit 22 (step 201). Thereafter, the dial number r3Jr5Jr5Jr7J is input and the SET button 27 is pressed (step 210).
), the ear number with the registration number r24J is registered (step 213), and the audio data "Uketsuke" is also registered.

Here, the CPU 30 increments the registration number to "25" (step 216), and also increments the registration number "
5" is less than or equal to the maximum number of registered words "s" (step 217). In this case, since the judgment result is @NO#, the CPU 30 calculates the number of registered words by subtracting "1" from the current registration number ("5" in this case), that is, "
"Required" automatically (step 218). Setting the number of registered words means setting the number of words to be searched in the auto dialing mode described later. In this case, all registered contents from registration number "1" to "Sae" are searched. When the number of registered words is set in this way, the CPU 30
The program returns to the main routine from the dialed number routine.

The above is an example of data registration up to the maximum number of registered words (24). For example, from registration number "1" to rlOJ
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 turning on the 8ET button 27, the CPU 30 inputs the current registration number (in this case "1").
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 confirm that the registration number is blinking, and then press the LRN button 25 as many times as the number of registration numbers to be skipped ( 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. Ru. For example, in the old registration, the number of registered words is set to 1o words with registration numbers "1" to "10", and in the new registration, after the re-registration of 5 words with registration numbers "1" to "5" is completed. If the SET button 27 is pressed in step 205, the number of registered words will be set to five words from registration numbers "1" to "5", and the number of registered words will be set to five words from registration numbers "6" to "10" that have been registered since then. The registered contents are ignored from the search target.

In this case, if the 8ET button 27 is not pressed in step 205 and the CAM button 26 is pressed in step 206, the number of registered words will not be revised. In other words, in this case, 1 consists of the new registration contents with registration numbers "1" to "5" and the old registration contents with registration numbers "6" to "10".
0 words are searched. In this way, this step 2
06ζ If you press the CAN button 26 at this point, you can return the program to the main routine without changing the number of registered words.
Used in conjunction with the registration number skip function to revise some of the registration details.

G4. Auto dial mode Next, Figure 8 shows CPU 3 in auto dial mode.
2 shows an example of a control flowchart for No. 0.

First, the operator inserts the memory unit 50 in which the desired destination is registered into the insertion slot 59 of the voice recognition dial device 2.

Next, the operator picks up the handset of the telephone 1 and presses the RCG button 24 (see FIG. 6). CPU
30 detects this, it sends a telephone line control signal to the interface circuit 10 via the input/output port 40, and changes the line from the state shown in FIG. 4(a) to the state shown in FIG. 4(b).
At the same time, the number of registered words stored in the registered word number memory 54 of the memory unit 50 is read out.
This is input to the speech recognition circuit 35 via the input/output port 36 (step 300). The number of words to be searched in the speech recognition circuit 35 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
5, 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 speech patterns pre-stored in the speech pattern memory 52 of the memory unit 50, from the registration number rlJ to the registration number rnJ (n = number of registered words) designated by the number of registered words. , reports the matching result to the CPU 30 via the input/output port 36 (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). 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 51 in the memory unit 50 and inputs it to the DA converter 37. The DA converter 37 converts the input PCM signal into an analog signal, and supplies this converted analog signal to the handset of the telephone 1 via the filter 38, amplifier 39, and interface circuit 10 (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 input by the user are reproduced, the user turns on the handset, waits until the lamp h 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 finished, the CPU 30 reads out the dial number corresponding to the registration number obtained as the verification result from the telephone number memory 53 in the memory unit 50, and controls the telephone line via the input/output port 40. The signal is sent to the interface circuit 10, the line is switched from the state shown in FIG. 4(b) to the state shown in FIG. 4(C), and a dial pulse signal corresponding to the dial number read above is sent to the central office line. Select (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, and changes the line from the state shown in FIG. 4(C) to the state shown in FIG. > to disconnect the voice recognition dial device 2 from the central office line. Once the line with the other party is established, the operator can then 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 equal to the external line connection time of the exchange, and sends a dial pulse.

In this way, in this embodiment, a dial number registration mode and an auto dial mode are provided to realize automatic dialing by voice input, and the memory in which the telephone number, voice pattern, and voice are stored is made into a unit, and the memory H device It is designed to be detachable from the main body. Therefore, when dialing, the operator can easily perform automatic dialing by simply attaching a memory unit in which data regarding the desired communication partner is registered to the device, and then uttering the same words as the registered voice corresponding to the desired communication partner. be able to.

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 even more functions may be provided to one button 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 Furthermore, the number of registered words is 2
It is sufficient to use any maximum number of gold and silver words, not just 4 words, and the registration numbers to be displayed are rOJ, rlJ in order 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 SET button 27 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, the telephone 1 and the voice recognition dialing device R2 are configured as separate units as shown in FIG. 1, 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
In the above, a dial pulse (DP) signal is sent to the line, but it is of course possible to send a pushbutton (PB) signal consisting of a combination of two audio signals to the line. be.

By the way, in the above embodiment, the voice memory 51, the voice pattern memory 52, and the telephone number memory 53 each have the same storage area divided by registration number, but the data length of each memo 'J51, 52, and 53 If you make it variable and store it sequentially from the first address without empty space, you can reduce the memory capacity.

Furthermore, in preparation for an increase in registered data, it is also possible to configure the voice memory 51, voice pattern memory 52, and telephone number memory 53 to be expandable in advance, and furthermore, each of these memories can be configured with an EP-ROM. Instead of writing by the CPU as in the above embodiment, the registration data may be written by an EP-ROM writing device.

Furthermore, in the above embodiment, among all the registered data in the voice pattern memory 52, from the registration number "1" to the registration number rn.
Although all registered data up to J (n: number of registered words) are searched by the speech recognition circuit 35, the manner in which the search targets are selected is arbitrary; for example, registration numbers "1", "5"
”, “7”, etc., it is easily possible to search for registration contents corresponding to skipped registration numbers.

Further, in the above embodiment, a connector connection may be adopted in which a male contact is provided on the insertion port 59 side of the device 2 and a female contact is provided on the memory unit 5o side.

Further, in the above embodiment, an IC or LSI is used as the memory unit 50, but a mechanical drive means may be provided on the voice recognition dial device 2 side and a cassette type magnetic tape may be used as the memory unit 50. good. Although the memory unit 5o can be attached or detached at any position, it is preferable to install it at the rear of the device if the memory unit 5o is attached and detached less frequently.

Furthermore, 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
The configuration may be such that registration data input by the operator that allows re-registration is stored in a RAM provided separately from the OM. In this case, it is preferable that the ROM is built into the voice recognition dialing device 2, and only the RAM that can be reregistered is made into a unit, so that it can be detached from the main body of the device.

As described in detail of the H8 invention, according to the voice dialing telephone device according to the present invention, the destination is selected by voice input and automatic dialing is performed for the destination. There is no need for any key operation at all for selection, which enables efficient dialing and contributes to miniaturization of the device. Furthermore, in this invention, the memory for storing the voice pattern and telephone number corresponding to a predetermined voice is made into a unit, and this is configured to be detachable from the main body of the device. If a plurality of devices are prepared correspondingly, it is possible to easily perform an automatic dial link according to each speaker's request without changing the operating procedure of the device.
