SYSTEM AND METHOD FOR OPERATING DEVICES USING VOICE COMMANDS

摘要

System and method for operating electric devices based on voice commands, as well as electric devices that can be controlled via voice commands. An electric device comprises an audio sensor to capture audio that contains speech; and a transmitter to transmit the captured audio to a remote server, together with a dictionary identifier that indicates to the remote server which particular dictionary or vocabulary-set to utilize for performing speech recognition on the recorded audio. The remote server performs speech recognition using the relevant dictionary table; and selects a command-code that is transmitted back to the electric device, to trigger an operational modification of the electric device.

主权项

1. A control component to enable operation of an electric device via voice commands, the control component comprising:
an audio sensor to capture audio; a voice detector to detect speech uttered within said audio; an audio recorder to record audio captured by said audio sensor, during a time-period in which speech is detected by said voice detector within said audio; a wireless transmitter to wirelessly transmit to a remote server, over one or more wireless communication links, a message comprising: (A) digital data reflecting the recorded audio; (B) a Dictionary Identifier Code (DIC) to indicate a particular dictionary table that should be used for performing speech recognition on said recorded audio, out of multiple dictionary tables that correspond to multiple different electric devices that are voice-controllable; a wireless transceiver to wirelessly receive from said remote server, over one or more wireless communication links, data representing a command code determined by said remote server based on speech recognition performed by said remote server on said recorded audio, wherein the command code represents a pre-defined command to the electric device to modify one or more operational parameters of the electric device; an operation control module to trigger one or more modifications to the operation of the electric device, based on the received command code.
