Abstract:
Systems and methods for three-dimensional beamforming disclosed herein include, among other features (i) generating a set of received-sound beams by applying a plurality of sets of beamforming coefficients stored in a tangible memory of the network device to sound received via a microphone array of the network device, wherein each received-sound beam corresponds to a separate direction relative to the microphone array, (ii) identifying a subset of the received-sound beams comprising speech content, (iii) for each received-sound beam in the subset of the received-sound beams comprising speech content, determining whether the speech content comprises a wake word, (iv) selecting one final received-sound beam from the received-sound beams in the subset of the received-sound beams determined to comprise a wake word; and (v) causing the selected one final received-sound beam to be processed to identify a voice command.

Claim (Index 13):
The tangible, non-transitory computer readable medium of  claim 12 , wherein selecting for further processing, two or more received-sound beams having a high likelihood of speech content and a low correlation with each other based on the cross-correlation matrix comprises:\n ranking each received-sound beam based on its likelihood of comprising speech content; and based on the ranking, selecting a top subset of two or more least-correlated received-sound beams for further processing.
