Abstract: The disclosure describes keyword detection in an audio processor and methods therefor including a low-power keyword detection engine (LKDE) and a high-power keyword detection engine (HKDE). In one implementation, the LKDE detects a keyword in data from a single audio source while buffering data from multiple audio sources and, upon detection of a keyword, the HKDE is awakened to verify the previously detected keyword by processing the buffered audio data from the multiple sources.
