Patent ID: 8645132

Claim:
A method comprising: receiving a first audio signal; identifying the first audio signal; selecting one of a plurality of recognition sets to recognize one or more predetermined utterances based on the identified first audio signal; configuring a recognizer to recognize the one or more predetermined utterances in the presence of a non-random information bearing background audio signal having particular audio characteristics, said configuring desensitizing the recognizer to signals having said particular audio characteristics; receiving, in the recognizer, a composite signal comprising the first audio signal and a spoken utterance of a user, wherein the first audio signal is generated by an electronic speaker, wherein the first audio signal comprises said particular audio characteristics used to configure the recognizer so that the recognizer is desensitized to the first audio signal; recognizing the spoken utterance in the presence of the first audio signal when the spoken utterance of the user is one of the predetermined utterances; executing a command corresponding to a particular one of the predetermined utterances having been recognized; and performing an operation corresponding to the command on the first audio signal in response to the command, wherein when different audio signals are identified, different recognition sets are dynamically selected and used to configure the recognizer so that the recognizer is desensitized to the identified audio signals, and wherein the different audio signals are associated with different commands executed when an utterance is recognized.
