US Patent Issued to AONDEVICES on May 20 for "Multistage low power, low latency, and real-time deep learning single microphone noise suppression" (California Inventors)

ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,042, issued on May 20, was assigned to AONDEVICES INC. (Irvine, Calif.).

"Multistage low power, low latency, and real-time deep learning single microphone noise suppression" was invented by Mouna Elkhatib (Irvine, Calif.) and Adil Benyassine (Irvine, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A multi-stage noise suppression system for reducing noise components in a noisy input signal has a first stage neural network that estimates a noise power spectrum for the noisy input signal. A first set of gain values corresponding to the noise power spectrum is generated by the first stage neural network. A second stage neural network estimates cle...
