Abstract:
Provided are systems and methods for utilizing digital microphones in low power keyword detection and noise suppression. An example method includes receiving a first acoustic signal representing at least one sound captured by a digital microphone. The first acoustic signal includes buffered data transmitted with a first clock frequency. The digital microphone may provide voice activity detection. The example method also includes receiving at least one second acoustic signal representing the at least one sound captured by a second microphone, the at least one second acoustic signal including real-time data. The first and second acoustic signals are provided to an audio processing system which may include noise suppression and keyword detection. The buffered portion may be sent with a higher, second clock frequency to eliminate a delay of the first acoustic signal from the second acoustic signal. Providing the signals may also include delaying the second acoustic signal.

Claim (Index 17):
An audio processing system comprising:\n a digital microphone having a buffer and an internal clock, the digital microphone configured to capture sound and buffer data representative of the captured sound using the internal clock, and to transmit a first signal including the buffered data; a second microphone configured to capture the sound and transmit a second signal representative of the captured sound, the second signal including real time data, the buffered data delayed relative to the real-time data; a processor communicatively coupled to memory storing instructions which, when executed by the processor, configure the processor to: receive the first signal and the second signal; prepend the buffered data to the real time data.
