US Patent Issued to Amazon Technologies on April 7 for "Noise suppression using subspace processing" (California Inventor)

ALEXANDRIA, Va., April 7 -- United States Patent no. 12,597,431, issued on April 7, was assigned to Amazon Technologies Inc. (Seattle).

"Noise suppression using subspace processing" was invented by Mohamed Mansour (Cupertino, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system configured to perform noise suppression using subspace processing. For example, a device may estimate a multichannel noise subspace and use the estimated noise subspace to perform noise suppression while preserving coherence between microphones, enabling further processing (e.g., beamforming, SSL processing). The device may estimate the noise subspace during non-speech activity to determine a set of principal noise component...
