Abstract
Techniques related to a method and system of audio false keyphrase rejection using speaker recognition are described herein. Such techniques use speaker recognition of a computer originated voice to omit actions triggered when a keyphrase is present in captured audio and omitted when speech of the captured audio was spoken by the computer originated voice.
Claims25
A computer-implemented method of false keyphrase rejection comprising:
- receiving a captured audio signal of sound captured from at least one microphone;
- detecting whether or not the captured audio signal includes speech spoken by at least one computer originated voice;
- and
- omitting an action to be triggered when one or more keyphrases are present in the captured audio signal, and omitting the action at least partly depending on whether the at least one computer originated voice was recognized in the captured audio signal.
An audio processing device comprising:
- at least one microphone;
- a capture path receiving captured audio signals of sound captured by the at least one microphone;
- at least one processor communicatively coupled to the capture path;
- a speaker recognition unit operated by detecting whether or not the captured audio signal includes speech spoken by at least one computer originated voice;
- and
- a keyphrase detection unit to be operated by omitting an action to be triggered when one or more keyphrases are present in the captured audio signal, and omitting the action at least partly depending on whether the at least one computer originated voice was recognized in the captured audio signal.
At least one non-transitory machine readable medium comprising a plurality of instructions that, in response to being executed on a computing device, cause the computing device to operate by:
- receiving a captured audio signal of sound captured from at least one microphone;
- detecting whether or not the captured audio signal includes speech spoken by at least one computer originated voice;
- and
- omitting an action to be triggered when one or more keyphrases are present in the captured audio signal, and omitting the action at least partly depending on whether the at least one computer originated voice was recognized in the captured audio signal.
