Patent number: 12217761Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media relate to a method for target speaker extraction. A target speaker extraction system receives an audio frame of an audio signal. A multi-speaker detection model analyzes the audio frame to determine whether the audio frame includes only a single-speaker or multiple speakers. When the audio frame includes only a single-speaker, the system inputs the audio frame to a target speaker VAD model to suppress speech in the audio frame from a non-target speaker based on comparing the audio frame to a voiceprint of a target speaker. When the audio frame includes multiple speakers, the system inputs the audio frame to a speech separation model to separate the voice of the target speaker from a voice mixture in the audio frame.Type: GrantFiled: October 31, 2021Date of Patent: February 4, 2025Assignee: Zoom Video Communications, Inc.Inventors: Yuhui Chen, Qiyong Liu, Zhengwei Wei, Yangbin Zeng

Patent number: 12207063Abstract: Example methods and systems provide automatic audio equalization for online conferences. A target, ideal, audio frequency response for use in online conferencing audio can be designed and preset for reference, and the equalizer can operate in real time to reach the target frequency response for any input. The equalizer can selectively apply per-band equalization to the audio signal as needed to adjust an energy value for each of multiple frequency bands to produce an output audio signal that that can be, as an example, routed through meeting servers or other infrastructure to other conference participants. The equalization can compensate for conditions local to a speaker that would otherwise adversely affect audio quality.Type: GrantFiled: September 26, 2022Date of Patent: January 21, 2025Assignee: Zoom Video Communications, Inc.Inventors: Yuhui Chen, Zhaofeng Jia
