ALEXANDRIA, Va., June 10 -- United States Patent no. 12,293,769, issued on May 6, was assigned to TENCENT AMERICA LLC (Palo Alto, Calif.).
"Neural-echo: an unified deep neural network model for acoustic echo cancellation and residual echo suppression" was invented by Meng Yu (Palo Alto, Calif.) and Dong Yu (Palo Alto, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method, computer program, and computer system is provided for an all-deep-learning based AEC system by recurrent neural networks. The model consists of two stages, echo estimation stage and echo suppression stage, respectively. Two different schemes for echo estimation are presented herein: linear echo estimation by multi-tap filtering on ...
