Voice-operated remote control system
First Claim
1. A voice-operated remote control system for use with an information reproducing device which reproduces sound through acoustic radiating means at an adjustable sound pressure level, said 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, adapted to be associated with the information reproducing device, for receiving the remote control signal, decoding the remote control signal into a control command, and supplying the control command to the information reproducing device;
said transmitter having detecting means for detecting whether a voice command is to be applied thereto and producing a detected signal, and mute control means for lowering the sound pressure level of the sound reproduced by the information reproducing device depending on said detected signal from said detecting means, before the voice command starts being applied.

Abstract
A voice-operated remote control system has two microphone and an ambient noise remover in a transmitter. One of the microphones picks up a voice command, and the other picks up ambient noise. When the voice command is picked up by one microphone, the ambient noise is also picked up thereby. The ambient noise remover cancels an ambient noise component with an electric signal of the ambient noise picked up by the other microphone, and outputs only a voice command component. The remote control system may have a voice command detector and a mute control circuit. If the preparation of entry of a voice command is detected by the voice command detector, the mute control circuit lowers the sound pressure level of sound reproduced by an information reproducing device before the voice command starts being inputted. The remote control system may also have a recognition condition setting unit for automatically modifying speech recognition conditions if a voice command is rejected to be recognized. The remote control system may further include a speech storage unit for storing input voice commands and a speech reproduction unit for reproducing the stored voice commands as required.

4. 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.

5. 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. - View Dependent Claims (6, 7, 8, 9)
