Abstract
An automatic gain control method and apparatus, and a readable storage medium. The automatic gain control method includes: for a far-field speech signal of a current frame, distinguishing between a target signal and a non-target signal; according to a result of the distinguishing between the target signal and the non-target signal, determining a gain table calculation parameter of the far-field speech signal, and obtaining a gain variation of the far-field speech signal of the current frame relative to a previous frame; determining a gain value for the far-field speech signal of the current frame according to the gain variation; and processing the far-field speech signal of the current frame according to the gain value determined, to obtain a processed speech signal. The automatic gain control method can effectively increase the gain of the target signal and reduce the gain of the non-target signal when gaining the far-field speech signal.
