Voice-operated remote control system

A voice-operated remote control system comprising:

• a transmitter comprising;
• a microphone for converting a voice command into an electric signal;
• standard pattern data registering means for registering standard pattern data in a registering mode;
• speech recognition means, operable in a recognition mode, for converting the voice command into pattern data based on the electric signal from said microphone, comparing the pattern data of the voice command with the registered standard pattern data, determining whether the result of comparison satisfies a speech recognition condition, and transmitting a remote control signal corresponding to the voice command when the satisfaction is determined;
• and
• a receiver for receiving the remote control signal, decoding the remote control signal into a control command, and supplying the control command to a controlled device;
• said transmitter having recognition condition setting means for automatically modifying said speech recognition condition, in the recognition mode, when the voice command is rejected by said speech recognition means, wherein said speech recognition condition is modified so as to increase the probability of subsequent recognition of said rejected voice command.

A voice-operated remote control system comprising:

• a transmitter for converting a voice command into a remote control signal and transmitting the remote control signal;
• and
• a receiver for receiving the remote control signal, decoding the remote control signal into a control command, and supplying the control command to a controlled device;
• said transmitter comprising:
• a speech storage unit for storing data corresponding to each voice command;
• and
• a speech reproduction unit for reading data of a voice command from said speech storage unit in response to an external reproduction command signal and converting and outputting the voiced command data into a corresponding audible voice output.
