Abstract
Abstract A voice-operated remote control system which transmits a remote control signal in response to a voice command has a detector for detecting whether a voice command is received or not. A detected signal from the detector is applied to a power supply control circuit. When there is no voice command received as detected by the detector, the power supply control circuit cuts off electric energy supplied to a speech recognition circuit which consumes the largest amount of electric energy in the voice-operated remote control system. The voice-operated remote control system also has a continuous operation instructing unit which produces an instruction signal that instructs a repetition command to cause a remotely controlled device to repeat an operation. The instruction signal is supplied to a continuous operation control unit which adds the repetition command to the remote control signal that is transmitted to the remotely controlled device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A voice-operated remote control system including a transmitter comprising: a switch disposed in one of an activated state and a deactivated state such that placing said switch in said activated state enables said transmitter and placing said switch in said deactivated state disables said transmitter; a microphone for converting a voice command into an electric signal; a first circuit for recognizing the voice command based on the electric signal from said microphone and producing command data corresponding to the voice command; a transmitter for generating and transmitting a remote control signal corresponding to said command data; a second circuit, responsive to said switch, for producing an instruction signal when said switch remains in said activated state for a predetermined time period to apply a repetition command to repeat an operation to a remotely controlled device; and a third circuit for adding said repetition command to said remote control signal in response to said instruction signal.
Claim 2
Dependent Claim
155 words
A voice-operated remote control system including a transmitter comprising: a switch disposed in one of an activated state and a deactivated state such that placing said switch in said activated state enables said transmitter and placing said switch in said deactivated state disables said transmitter; a microphone for converting a voice command into an electric signal; a first circuit for recognizing the voice command based on the electric signal from said microphone and producing command data corresponding to the voice command; a transmitter for generating and transmitting a remote control signal corresponding to said command data; a second circuit, responsive to said switch, for producing an instruction signal when said switch remains in said activated state for a predetermined time period to apply a repetition command to repeat an operation to a remotely controlled device; and a third circuit for adding said repetition command to said remote control signal in response to said instruction signal.
Claim 3
Dependent Claim
81 words
A voice-operated remote control system according to claim 1, further comprising: power supply circuit for supplying electric energy to said speech recognition means and said transmitting means; a fourth circuit for producing a detected signal indicative of whether a voice command is received or not; and power supply control circuit for cutting off the electric energy from said power supply circuit to at least said speech recognition means in the absence of a voice command as indicated by said detected signal.
Claim 4
Dependent Claim
33 words
A voice-operated remote control system according to claim 1, further comprising a casing which houses therein said switch, said microphone, said first, second, and third circuits, said transmitter, and said power supply circuit.
Claim 5
Dependent Claim
37 words
A voice-operated remote control system according to claim 3, wherein said casing houses therein a talk switch for instructing the start and end of a process which are indicated by a voice command received by said microphone.
Claim 6
Dependent Claim
42 words
A voice-operated remote control system according to claim 4, wherein said talk switch produces a signal to allow a process which is indicated by a voice command received by said microphone to be carried out only when the talk switch is pressed.
Claim 7
Dependent Claim
29 words
A voice-operated remote control system according to claim 4, wherein said second circuit comprises said talk switch, and produces said instruction signal when the talk switch is continuously pressed.
