DYNAMIC ADJUSTMENT OF WAKE WORD ACCEPTANCE TOLERANCE THRESHOLDS IN VOICE-CONTROLLED DEVICES

Abstract:

Systems and methods are provided for detecting wake words. An electronic device detects, from a microphone array, an audio signal in an environment proximate to the audio front end system. The electronic device processes the audio signal using a plurality of wake word detection engines, including dynamically adjusting how many wake word detection engines are available for processing the audio signal. The electronic device independently adjusts respective wake word detection thresholds for the plurality of wake word detection engines used to process the audio signal.
