Original Abstract Submitted
this disclosure provides methods, devices, and systems for signal processing. the present implementations relate more specifically to a spatio-temporal beamformer. in some aspects, a beamforming system may receive an audio signal via a plurality of microphones, the audio signal including a number (b) of frames for each of the plurality of microphones, each of the b frames for each of the plurality of microphones including a number (n) of time-domain samples. for a first microphone, the beamforming system may transform the b*n time-domain samples into b*n/2 first frequency-domain samples; transform the b*n/2 first frequency-domain samples into b*n/2 second frequency-domain samples; and determine a probability of speech associated with the b*n/2 second frequency-domain samples based on a neural network model. the beamformer system may determine a minimum variance distortionless response (mvdr) beamforming filter based at least in part on the probability of speech for the first microphone.
