US Patent Issued to Dolby Laboratories Licensing on Nov. 3 for "Reverb and noise robust voice activity detection based on modulation domain attention" (Chinese Inventors)

ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,784,768, issued on Nov. 3, was assigned to Dolby Laboratories Licensing Corp. (San Francisco).

"Reverb and noise robust voice activity detection based on modulation domain attention" was invented by Shaofan Yang (Beijing) and Kai Li (Beijing).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system for detecting speech from reverberant signals is disclosed. The system is programmed to receive spectral temporal amplitude data in the modulation frequency domain. The system is programmed to then enhance the spectral temporal amplitude data by reducing reverberation and other noise as well as smoothing based on certain properties of the spectral temporal spect...
