JPS59225656A - Telephone terminal device for voice dial - Google Patents

Abstract

PURPOSE:To obtain a telephone terminal device requiring no visual confirmation or manual operation by identifying a voice input, generating an address corresponding to voice input information, generating telephone number information in response to the said address from a memory and allowing dialing in response to the said information. CONSTITUTION:A voice input 1 at the telephone terminal device is converted into an electric signal via a microphone 2. An electric signal output of the microphone 2 is subjected to the required amplification via an amplifier 3 and inputted to a voice recognizing section 4. The voice recognizing section 4 identifies an input signal under the control of a control section 11 and generates address information. This address signal is fed to a memory 6 via an address bus 5, and the memory 6 outputs a code of a telephone number corresponding to the address information. A number converting section 8 receives an output of the memory 6 via a data bus 7, converts the output into an electric signal of the telephone number under the control of the control section 11 and outputs the result sequentially one by one digit. A transmission section 9 receives an electric signal of the number converting section 8, generates a dial pulse corresponding thereto and transmits the pulse to a transmission line 10.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to telephone terminals, and more particularly to a voice dial telephone terminal C2 that can automatically dial the telephone number of a person with whom one wants to talk by voice input.

Prior Art and Problems In the conventional telephone terminal G2, in order to input the telephone number of the person with whom you wish to talk, you have to manually enter it by dialing or operating a button. For this reason, not only is it necessary to confirm the telephone number of the person on the other end of the call each time a call is made, but there are also many cases of incorrect dialing due to operational errors. As one method to solve these drawbacks, a speed dial system is also used, which allows a specific number to be dialed using a short combination of specific codes and numbers (an abbreviated number consisting of two characters). In this case as well, you must visually check the speed code keys and operate the keys manually.In addition, such manual operations are performed on the premise that you visually check the dials, buttons, keys, etc. This can be a huge burden for some visually impaired people.

Purpose of the Invention The present invention solves the problems of the prior art.
□The purpose is to make it possible to enter a telephone number by voice input on a telephone terminal, thus creating a voice dial system that does not require visual confirmation or manual operation. The purpose is to provide telephone terminals.

Structure of the Invention The voice dial telephone terminal of the present invention inputs a voice signal through a microphone or the like, identifies this signal, and reads out a telephone number corresponding to the voice input stored in a memory in advance according to the identification result. This system is designed to automatically send a dial pulse corresponding to the read telephone number.

EMBODIMENT OF THE INVENTION The figure shows the configuration of an embodiment of the voice dial telephone terminal of the present invention. Figure (2) 1 is a voice input, 2 is a microphone, 6 is an amplifier, 4 is a voice recognition section, 5 is an address bus, 6 is a memory, 7 is a data bus, 8 is a number conversion section, 9 is a transmission section, 10 11 is a transmission path, and 11 is a control section.

Voice input 1 at telephone terminal C2 is converted into an electrical signal via microphone 2. The electrical signal output from the microphone 2 is input to the speech recognition section 4 after being amplified as required through the amplifier 5 . The voice recognition unit 4 identifies the input signal under the control of the control unit 11 and generates address information in accordance with the identification result. This address signal is sent to the memory 6 via the address bus 5, and the memory 6 Under the control of section 11, a telephone number code is output in correspondence with address information≦2.

The number converter 8 receives the output from the memory 6 via the data bus 7, converts it into an electrical signal of a telephone number, and sequentially outputs it one digit at a time under the control of the controller 11.

The transmitter 9 receives the electrical signal from the number converter 8, generates a corresponding dial pulse, and sends it to the transmission line 10.

In this case, the voice input may be a keyword representing the telephone number, or may be the telephone number itself. When the voice input is a keyword, the voice recognition section identifies this and generates an address for accessing information on all digits of the telephone number, and the memory outputs codes for all digits of the telephone number in parallel. The number converter converts this into an electrical signal of numbers and outputs the electrical signal one digit at a time. When the voice input is a telephone number, the voice recognition section identifies this and generates an address for each digit of the telephone number, and the code of the telephone number is outputted from the memory one digit at a time. The number conversion section sequentially converts this into an electrical signal of numbers and outputs it.

Note that speech recognition devices that identify speech input and generate information such as a corresponding address are well known and have already been put into practical use.

As described in detail, the voice dialing telephone terminal of the present invention identifies voice input, generates an address corresponding to the voice input information, and generates telephone number information from memory in accordance with this address. Now, dialing is performed based on this information (2), so when you try to make a call, you don't have to manually operate dials or buttons, just enter the keyword or phone number that represents the other party by voice, and the call is automatically dialed. This not only simplifies the procedures necessary for making a call by eliminating the need for visual confirmation or manual operation, but also eliminates the risk of operational errors. This is especially important for free people.
