Abstract:
Methods of low power detection of an activation phrase are described. A microphone system comprises dedicated hardware logic for detecting a pre-defined activation phrase in an audio stream received via a microphone. If the pre-defined activation phrase is detected, the hardware logic sends a trigger signal to activate a module, such as a main speech detection module, which is external to the microphone system and which may be in a low power standby state.

Claim (Index 14):
The voice controlled device of  claim 1 , wherein the microphone system is further configured to compare the audio stream received via the microphone with the pre-defined activation phrase in a first mode of operation, and is further configured to switch to a second mode of operation in response to detecting the pre-defined activation phrase in the audio stream, wherein the main speech detection module is configured to detect the multiple phrases in the second mode of operation based on the audio stream and wherein, the dedicated hardware logic is bypassed and the main speech detection module receives the audio stream directly from the microphone in the second mode of operation.
