Abstract

PURPOSE:To read a destination not talked due to a busy state automatically later and to attain dialing by registering only a busy destination once. CONSTITUTION:When a busy tone signal detection section 15' in a line control section 15 detects it that a called party is busy, a central control section 6 registers a dialed number to a 2nd number storage section 12. When the user lifts up its handset and hooks off, the central control section 6 reads the telephone number stored by the 2nd number storage section 12 automatically and reads a voice standard pattern corresponding to the telephone number from a standard pattern storage section 4 (or 7), gives a command to a voice output section 5, from which a voice signal is outputted. Thus, when the opposite party is busy and called back later, the load of the user is relieved and efficient callback is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice dialing device, and more particularly to a device that automatically dials a call based on the result of voice recognition.

BACKGROUND OF THE INVENTION Conventional Light Projection Conventional telephone dialing devices require manual dialing to input the dial number of the other party's telephone subscriber when making a call. This type of dialing device places a heavy burden on the user, such as having to memorize the dial number of the other party when making a call or refer to the dial number of the other party in a memo or the like. Therefore, a method has been proposed in which a dial signal is automatically output by voice input instead of manual dial operation.

According to this method, the user can memorize the dial number,
There is no need to operate dials while looking at notes etc. On the other hand, in recent years, general household telephones have also become multi-functional, and functions such as speed dialing, one-button dialing, and redialing have become commonplace. Among these functions, the redial function stores the most recent telephone number of a person to whom you have dialed in the past, and then re-dials the phone number. However, people who frequently use telephones for sales, etc., may call someone else if the person they are calling is busy, then call the other person again after finishing their business. Occurs in many cases. In this case, the conventional redial function cannot be used.

Additionally, some devices have a function of keeping a history of past dial calls and selecting one from the list to make a call, but this requires an operation of calling up the past history and making a selection.

Purpose The present invention was made in view of the above-mentioned circumstances.
In particular, in a voice dialing device that automatically dials a call based on voice recognition results, when the other party is busy and calls back later, it is possible to reduce the burden on the user and efficiently make the call back. With the goal.

In order to achieve the above object, the present invention provides: (1) a feature extraction unit that extracts the feature amount of the voice for a name input by voice; a standard pattern storage unit that stores feature quantities as standard patterns; a first number storage unit that stores dial numbers corresponding to names input by voice; and feature quantities extracted by the feature extraction unit during voice input; A pattern matching unit that recognizes which standard pattern the input voice corresponds to by performing pattern matching with the feature amounts in the Il$ pattern storage unit stored in advance; and a recognition result of the pattern matching unit. an audio output unit that reads a standard pattern from the standard pattern storage unit or another pre-stored standard pattern storage unit and synthesizes and outputs an audio signal from the standard pattern; and a name corresponding to the recognition result by the pattern matching unit. A voice dialing device comprising: a calling circuit that reads a dialed number from the number storage section and outputs a dialing signal; a busy signal identification section that identifies a busy signal of a called party; a second number storage unit for storing numbers; when dialing a destination registered in the standard pattern storage unit and the first number storage unit, and going on-hook because the destination is busy; The telephone number of the other party is stored in the second number storage section, and the next time you go off-hook, the telephone number stored in the second number storage section and the standard pattern corresponding to the telephone number are stored in the standard pattern storage section. A voice dial system that notifies the user of the number to which the user was previously speaking by reading out the phone number, synthesizing and outputting the audio signal from the audio output unit, and automatically dialing the phone number after the user confirms the call. (2) In the voice dialing device, after a number is stored in the second number storage section, the telephone number stored in the number storage section is read out and dialed. (3) If the number is not dialed even after a predetermined period of time has passed after the number is stored in the second number storage, Clearing the telephone number stored in the number storage unit, or (4) If the number is dialed within a predetermined time after the number is stored in the second number storage unit and the phone number is busy again, It is characterized by restarting the time counting from the beginning. Hereinafter, the present invention will be explained based on examples.

FIG. 1 is a block diagram for explaining one embodiment of the present invention, in which 1 is a transmitter, 2 is a receiver, 3 is a feature extraction unit, and 4 is a configuration diagram for explaining an embodiment of the present invention.

15 is a line control unit, 16 is a central office line, and in the present invention, 1
The line control section 15 includes a busy tone signal detection section 15'-- which detects whether the called party is busy or not. That is, the present invention includes a feature extractor 3 that extracts the feature amount of the voice for a name input by voice, and a standard pattern memory that stores the feature amount extracted by the feature extractor 3 as a standard pattern. unit 7, a first telephone number storage unit 11 that stores the dial number corresponding to the name input by voice, and the feature amount extracted by the feature extraction unit 3 at the time of voice input and the standard pattern stored in advance. A pattern matching unit 8 recognizes which standard pattern the input voice corresponds to by performing pattern matching with the feature amount in the storage unit 7, and the standard pattern corresponding to the recognition result of the pattern matching unit 8 is described above. Reading from the standard pattern storage section 7 or another standard pattern storage section 4 stored in advance.

An audio output unit 5 synthesizes and outputs an audio signal from the standard pattern, and reads out the dial number of the name corresponding to the recognition result by the pattern matching unit 8 from the first number storage unit 11 and outputs the dial signal. In a voice dialing device comprising a transmission circuit 10, a line control unit 1 serves as a busy tone signal detection unit 15' for identifying a busy signal from a called side.
5), and a second number storage section 12 that stores the telephone number of the other party who is currently on the line, and is registered in the standard pattern storage section 7 and the first number storage section 11. When you dial a destination and go on-hook because the other party is busy, the telephone number of the other party is stored in the second number storage unit 12, and the next time you go off-hook, the second number storage unit 12 and the standard pattern corresponding to the telephone number are read from the standard pattern storage section 7 or the synthesis standard pattern storage section 4, and the audio signal is synthesized and outputted from the audio output section 5. , the user is informed of the number to which the call was previously made, and after the user's confirmation, the telephone number is automatically dialed.
After the number is stored in the number storage unit 12 of the device, when the phone number stored in the number storage unit 12 is read out and dialed, the phone number stored in the number storage unit 12 is cleared, or , if the dialing is not made even after a predetermined period of time has passed after the number is stored in the second number storage section 12, the telephone number stored in the number storage section 12 is cleared, or the second number storage section 12 Number storage section 1
After the number is stored in 2, if a call is made within a predetermined time and the call is busy again, the predetermined time count is restarted from the beginning.

Further, to explain in detail with reference to the flowchart in FIG. 2, FIG. 2(,) shows the flowchart at the time of registration in the second number storage unit 12, and FIG. 2(b) shows the flowchart after registration. In the figure, first, it is assumed that one or more destinations have already been registered in the standard pattern storage section 7. Now, in FIG. 2(a), it is assumed that the user uses the voice dialing function to dial a certain destination. Here, when the busy tone signal detection section 15' provided in the line control section 15 detects that the called party is busy, the central control section 15' detects that the called party is busy.
Then, the dialed number dialed at this time is registered in the second number storage section 12. After this, in FIG. 2(b), when the user picks up the receiver and goes off-hook, the central control unit 6 automatically reads out the phone number stored in the above manner from the second number storage unit 12. , reads out the standard pattern of voice corresponding to the telephone number from the standard pattern storage section 4 (or 7), gives an instruction to the voice output section 5, and performs voice output. When the user confirms this voice output and gives an instruction to dial, the central control unit 6 will:
An instruction is given to the calling circuit 10 to automatically dial. If you wish to make a dial call to a telephone number other than the telephone number registered in the second number storage section 12, dial in the normal manner. Good. Even if you make a call to another party from the time it is registered in the second number storage unit 12 until the first dialing, the second number will not be used until the new party is checked. The number storage section 12 is not updated. If one call is completed by dialing again after the call is busy, it can be determined that the purpose has been achieved, so the contents of the second number storage section 12 are cleared. In addition, it is often the case that the user wants to call again after a busy call is detected, and it is very annoying for the user if the voice of the other party who was previously busy is output every time. do. Therefore, even if the telephone number registered in the second number storage section 12 is not dialed, the second number storage section 12 is automatically cleared after a predetermined period of time (for example, about one hour) has elapsed.

Further, if the telephone number is called within a predetermined time and is busy again, the predetermined time is counted again from the beginning.

Effects As is clear from the above explanation, according to the present invention, by registering only the destinations that were already busy, the system automatically returns the destinations that could not be talked to due to business matters. can be read out and dialed.
