Description

The present invention relates to a voice recognition telephone having a redial function.

(B) Conventional technology Conventionally, there is a so-called multi-function telephone in which various functions are added to the original functions of the telephone, and one of them is a redial function. This is for remembering the telephone number of the other party dialed last, and by pressing the redial button when the other party is busy or absent, the same party's telephone number can be sent again.

In addition, recently, there is a telephone having a voice recognition function capable of transmitting a telephone number by using voice recognition. When numbers are recognized by voice and the result is output as a telephone number, the words to be used can be limited to numbers only or numbers and some control words. It can be used. However, in the case of recognizing the name of the other party by voice and transmitting a desired telephone number, since the other party varies depending on the user, it is more effective to use the specific speaker method in which the voice is registered in advance. In this case, a user designation means is provided so that a plurality of people can use one telephone, and the standard voice pattern registered in advance can be designated for each user by this user designation means. It is also possible to use the redial function by using voice recognition instead of pressing the redial button.

(C) Problems to be solved by the invention However, in the past, even if a plurality of users used the redialing button as described above, anyone could use the redialing function by pressing the redialing button. . Or even when using the redial function with voice recognition,
If at least the voice was registered in advance, a plurality of users could use the redial function.

Therefore, after the first user calls the desired telephone number,
By using the redial function by the second user,
There is a problem that it is difficult to keep the confidentiality because the telephone number transmitted by the first user is known to the second user.

(D) Means for Solving Problems The present invention provides a voice input means, a voice pattern creating unit that creates an input voice pattern from an input voice, and a standard voice pattern that stores a standard voice pattern for each user. A memory, a user designating means for designating a user, and a standard voice pattern in the standard voice pattern memory corresponding to the user designated by the user designating means are compared with the input voice pattern. An identification unit that outputs the result, a telephone number memory in which a telephone number is registered in advance, and a telephone number output unit that selects and outputs a predetermined telephone number from the telephone number memory according to the output from the identification unit. A redial memory for storing and updating the telephone number output by the telephone number output unit, and a redial means for outputting the telephone number stored in the redial memory from the telephone number output unit. Constituted by a repeat dialing memory clear means for erasing the telephone number stored in the redial memory detects it when the specified user has been changed by the use designation means.

(E) Action When the user's designation is changed by the user designation means, the redial memory clearing means detects the user's change and outputs a clear signal to the redial memory, so it is stored in the redial memory. Deleted phone number.

(F) Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention. (1) is a microphone for inputting voice, and (2) is a voice pattern creating unit for extracting features from the input voice and creating an input voice pattern. For example, (3) is a standard voice pattern memory in which standard voice patterns of four users are registered in advance for each user, and (4) is a standard voice pattern and an input voice pattern in the standard voice pattern memory (3). An identification unit for comparing the results and outputting the result, (5) a telephone number memory in which a telephone number is registered in advance, (6) a telephone number corresponding to the identification result in the identification unit (4) in the telephone number memory (5) A telephone number output section which is selected from the following and outputs as a tone signal or a pulse signal, and (7) is a redial memory which stores the telephone number output by the telephone number output section (6) while updating it.

(8) is a line interface circuit that sends out the telephone number output by the telephone number output unit (6) to an external line, and then enables a call. (9) is the redial button, and redial memory
The telephone number stored in (7) is output from the telephone number output unit (6). (10) is a control unit that detects that the telephone number is output from the line interface circuit (8) to the external line, and (11) is controlled by the control unit (10) and outputs the voice input to the microphone (1). A switch for sending to either the pattern creating unit (2) or the line interface circuit (8).

(12) is a user specified button, (13) is a user specified button (12)
Standard voice pattern memory corresponding to the user specified by
This is a switch for selecting the standard voice pattern in (3). (1
Reference numeral 4) is a user change detection unit that detects a change in the user specified by the user specification button 12 and outputs a clear signal to the redial memory 7. (15)
Is a speaker.

The operation will be described below. When calling a telephone number using voice recognition, the control unit (10) first switches the switch (11) so that the voice from the microphone (1) is sent to the voice pattern creating unit (2). . The first user sets the user designation button (12) to point to the first user. As a result, the switch (13) is switched so that the identification unit (4) is connected to the memory in the standard voice pattern memory (3) in which the standard voice pattern corresponding to the first user is stored.

When, for example, "Headquarters" is generated toward the microphone (1) after setting, an input voice pattern of the voice "Headquarters" is created by the voice pattern creating unit (2). This input voice pattern is compared with the standard voice pattern corresponding to the first user in the standard voice pattern memory (3) in the identification unit (4). In the telephone number output section (6), the voice "HQ" identified in the identification section (4)
Select the phone number corresponding to from the phone number memory (5),
The telephone number is output to the line interface circuit (8) and the telephone number is stored in the redial memory (7).

The line interface circuit (8) sends the telephone number to the external line and notifies the control unit (10) of that fact.
(10) switches the switch (11) to the line interface circuit (8) side. This allows the first user to call the “head office”. If you cannot talk while talking, press the redial button (9) to display the telephone number of "Headquarters" in the redial memory (7).
Can be sent to an external line via the line interface circuit (8).

Next, in order for the second user to make a call in the same manner as described above, it is necessary to change the user designation button (12) to instruct the second user. At this time, the user change detection unit (14) detects the change from the first user to the second user, outputs a clear signal, and redials the memory.
Delete the phone number stored in (7).

In the above explanation, the redial button (9) is used to send the telephone number in the redial memory (7) to the external line, but the telephone number is output by voice recognition without using the redial button (9). Start the part (6) and redial memory
It is also possible to send the telephone number in (7) to an external line. In this case, in order for the second user to know the telephone number in the redial memory (7) stored by the first user, without changing the user-designated button (12), that is, the standard voice is used. It is necessary to perform voice recognition using the standard voice pattern for the first user in the pattern memory (3),
Usually, it is difficult to operate accurately, so it is effective in maintaining confidentiality.

Further, in order to surely delete the telephone number in the redial memory (7), the user designation may be intentionally changed by operating the user designation button (12).

(G) Effect of the Invention As is clear from the above description, according to the present invention, when the user designated by the user designating means necessary for performing voice recognition is changed, it is automatically stored in the redial memory. Since the telephone number is erased, it is not necessary to separately install a button or the like for erasing the telephone number in the redial memory to keep the confidentiality.
