METHOD AND APPARATUS FOR MITIGATING FALSE ACCEPTS OF TRIGGER PHRASES

摘要

An electronic device includes a microphone (108) that receives an audio signal, and a processor that is electrically coupled to the microphone (108). The processor (204, 300) detects a trigger phrase in the received audio signal and measure characteristics of the detected trigger phrase. Based on the measured characteristics of the detected trigger phrase, the processor (204,300) determines whether the detected trigger phrase is valid.
