Abstract

A voice-operated remote control system which transmits a remote control signal in response to a voice command has a speech recognition circuit for recognizing the voice command. The speech recognition circuit has standard pattern data storage unit for storing a plurality of standard pattern data with respect to each of voice commands. The input voice command is compared with the plural standard pattern data for accurate speech recognition.

Claims

1. A voice-operated remote control system comprising:

a microphone for converting a spoken voice command into an electric signal;

storage means for storing for said voice command a plurality of sets of different standard pattern data, each set of different standard pattern data being independently representative of said voice command as spoken by at least one speaker;

speech recognition means for converting the electric signal into pattern data and for comparing the pattern data with the plurality of sets of different standard pattern data to recognize one of the sets of the different standard pattern data as corresponding to the spoken voice command; and

transmitting means for generating and transmitting a remote control signal based on the recognized spoken voice command.

2. A voice-operated remote control system according to claim 1, further comprising a learning unit for automatically updating the stored standard pattern data in response to a change in pattern data of a newly entered voice command.

3. A voice-operated remote control system comprising:

a microphone for converting a spoken voice command into an electric signal;

means for converting the electric signal into pattern data;

a plurality of parallel speech recognition processors for independently evaluating the spoken voice command based on respective stored sets of different standard pattern data, each set of different standard pattern data being independently representative of said voice command as spoken by at least one speaker, and outputting respective recognition results;

means for selecting one of said recognition results to produce command data corresponding to the spoken voice command; and

transmitting means for generating and transmitting a remote control signal based on the spoken voice command.

4. A voice-operated remote control system according to claim 3, further comprising a learning unit for automatically updating the stored standard pattern data in response to a change in pattern data of a newly entered voice command.

5. A voice operated remote control system according to claim 3, wherein said stored sets of different standard pattern data of said parallel speech recognition processors include data for a plurality of different voice commands.
