Abstract
A system and method capable of distinguishing sources in a multiple source environment is provided. The system receives an audio signal comprising an audio tag, a desired audio signal and an undesired audio signal. Based on the audio tag, the system eliminates the undesired audio signal and identifies an intended command in the desired audio signal. The system generates a command for an external device based on the intended command.
Claims22
An audio system, comprising:
- a memory device comprising a speech recognition algorithm and audio tags;
- a processor coupled to the memory device, a source of undesired audio signal and a source of desired audio signal, the processor configured to
- (i) receive an audio signal comprising (a) an undesired audio signal from the source of undesired audio, (b) a desired audio signal from the source of desired audio signal, the source of the undesired audio signal and the source of the desired audio signal being separate, and (c) an audio tag associated with one of the undesired audio signal or the desired audio signal,
- and
- (ii) based on the audio tag, eliminate the undesired audio signal from the audio signal prior to using the speech recognition algorithm to identify an intended command from the audio signal with the undesired audio signal eliminated.

An audio processing method, the method comprising:
- detecting, by an audio capture device, audio transmissions comprising (i) an undesired audio signal from a source of undesired audio, and (ii) a desired audio signal from a source of desired audio signal, the source of the undesired audio signal and the source of the desired audio signal being separate;
- converting, by the audio capture device, the audio transmissions into a collective audio signal comprising an audio tag, the desired audio signal and the undesired audio signal;
- receiving, at a processor, the audio signal comprising the audio tag, desired audio signal and undesired audio signal;
- processing the audio signal, using speech recognition algorithms stored in a memory device;
- eliminating the undesired audio signal from the audio signal based on the audio tag;
- and
- generating a command for an external device using the audio signal with the undesired audio signal eliminated.
