Abstract

A voice recognition system and method for training the same are provided wherein a first voice signal representing an instruction as well as a predetermined instruction signal corresponding to the first voice signal and identifying the instruction are input to the voice recognition system. The system processes the first voice signal based on the predetermined instruction signal to produce voice recognition data for use by the system in identifying the instruction based on a second voice signal representing the same instruction. The processor stores the voice recognition data for subsequent use upon receipt of the second voice signal and carries out the instruction in response to the predetermined instruction signal corresponding to the first voice signal.

Claims

1. A method for training and operating a voice recognition system, comprising the steps of:

inputting a first voice signal to a voice recognition system, the first voice signal representing an instruction for the system;

inputting a first predetermined instruction signal to the system, the first predetermined instruction signal corresponding to the first voice signal and identifying the instruction separately of the first voice signal;

processing the first voice signal based on the first predetermined instruction signal with the voice recognition system to produce voice recognition data for use by the system in identifying a second voice signal corresponding to the first voice signal and representing the instruction;

storing the voice recognition data in the system;

carrying out the instruction with the use of the voice recognition system in response to the first predetermined instruction signal corresponding to the first voice signal;

inputting the second voice signal;

identifying the instruction represented by the second voice signal based on the voice recognition data; and

carrying out the identified instruction.

2. The method of claim 1, further comprising the step of producing a training mode signal in response to the input of the first voice signal with the first predetermined instruction signal, and wherein the step of processing the first voice signal is carried out in response to the training mode signal.

3. The method of claim 1, further comprising the step of producing a voice recognition mode signal in response to the input of the second voice signal in the absence of the input of a corresponding signal with the second voice signal identifying the instruction separately from the second voice signal, and wherein the step of identifying the instruction represented by the second voice signal is carried out in response to the voice recognition mode signal.

4. The method of claim 1, further comprising the steps of producing a non-voice command signal in response to an input of a second predetermined instruction signal identifying the instruction and in the absence of a concurrent input of a voice signal to the system, and carrying out the instruction based on the second predetermined instruction signal and the non-voice command signal.

5. The method of claim 1, wherein the steps of inputting the voice signals comprise entering first and second voice signals representing an instruction for operating a telephone, and the steps of carrying out the instruction and the identified instruction comprise carrying out said instruction for operating a telephone.

6. The method of claim 1, wherein the steps of inputting the voice signals comprise entering first and second voice signals representing an instruction for operating a device selected from one of a television receiver, a video cassette recorder, a video game image processor, a high fidelity audio reproduction system and a compact disk player and the steps of carrying out the instruction and the identified instruction comprise carrying out the instruction for operating the selected device.

7. A voice recognition system, comprising:

a digital voice recognition processor programmed to receive a first voice signal corresponding to a predetermined instruction, a predetermined instruction signal corresponding to the first voice signal and identifying the instruction separately of the first voice signal, and a second voice signal representing the predetermined instruction;

means for inputting the first and second voice signals to the processor; and

means for inputting the predetermined instruction signal to the processor;

the processor being programmed further to process the first voice signal based on the predetermined instruction signal to produce voice recognition data enabling the processor to identify the instruction based on the second voice signal, to store the voice recognition data and to carry out the predetermined instruction based on the second voice signal and the voice recognition data;

the processor being programmed to carry out the predetermined instruction in response to the predetermined instruction signal corresponding to the first voice signal.

8. The voice recognition system of claim 7, wherein the digital voice recognition processor is operative to output a control signal upon carrying out the predetermined instruction.

9. The voice recognition system of claim 8, in combination with a telephone coupled with the output of the digital voice recognition processor to receive said control signal for controlling an operation of said telephone.

10. The voice recognition system of claim 8, in combination with one of a television receiver, a video cassette recorder, a video game image processor, a high fidelity audio reproduction system and a compact disc player coupled with said output to receive the control signal for controlling the operation thereof.

11. A voice recognition control system, comprising:

means for inputting a first voice signal representing an instruction for the system;

means for inputting a predetermined instruction signal corresponding to the first voice signal and identifying the instruction separately of the first voice signal; and

processing means for processing the first voice signal based on the predetermined instruction signal to produce voice recognition data for identifying a second voice signal corresponding to the first voice signal and representing the instruction;

the processing means being operative to store the voice recognition data in the system and to carry out the instruction in response to the predetermined instruction signal corresponding to the first voice signal;

the means for inputting the first voice signal being further operative to input the second voice signal;

the processing means being operative to identify the instruction represented by the second voice signal based on the voice recognition data and to carry out the identified instruction.

12. The voice recognition system of claim 11, wherein the processing means is operative to control operation of a telephone based on each of the predetermined instruction signal and the second voice signal.

13. The voice recognition system of claim 11, wherein the processing means is operative to control the operation of one of a television receiver, a video cassette recorder, a video game image processor, a high fidelity audio reproduction system and a compact disk player in response to each of the predetermined instruction signal and the second voice signal.
