MUMBAI, India, Sept. 5 -- Intellectual Property India has published a patent application (202348044452 A) filed by Google Llc, Mountain View, U.S.A., on July 3, 2023, for 'automatic gain control based on machine learning level estimation of the desired signal.'
Inventor(s) include Rudberg, Karl Allan Tore; and Bazzica, Alessio.
The application for the patent was published on Sept. 5, under issue no. 36/2025.
According to the abstract released by the Intellectual Property India: "Method includes receiving, through a plurality of channels, audio data corresponding to a plurality of frequency ranges; determining, for each channel's frequency ranges, speech audio and/or noise energy level using a model trained by machine learning; determining a speech signal with removed noise for each channel; determining one or more statistical values associated with an energy level of a channel's speech signal with the removed noise; determining a strongest channel that has highest statistical values associated with an energy level of a speech signal; determining that the one or more statistical values associated with the energy level of the strongest channel's speech signal satisfy a threshold condition; comparing statistical values associated with an energy level of a speech signal of each channel with those of the strongest channel; and determining whether to update a gain value for a channel based on the channel's statistical values associated with the energy level."
The patent application was internationally filed on Sept. 30, 2020, under International application No.PCT/US2020/053645.
