Abstract: Embodiments of the present disclosure provide a speech recognition method, a speech recognition apparatus, and a medium. The method includes: obtaining audio signals collected by microphones in at least two sound zones; determining whether each audio signal includes a key speech according to sound energy of the audio signal to acquire a determined result; adjusting an adaptive adjustment parameter of an adaptive filter in each sound zone according to the determined result; controlling the adaptive filter to perform adaptive filtering processing on the audio signal collected in the sound zone corresponding to the adaptive filter according to the adaptive adjustment parameter, and outputting a filtered signal; and performing speech recognition on the filtered signal.

Abstract: This application discloses a voice recognition method, a voice recognition apparatus, an electronic device and a computer readable storage medium, and relates to the field of voice recognition technology. A specific implementation is: performing a latency estimation according to a first microphone signal and a first reference signal in a preset time period to obtain a latency value; acquiring a system audio signal, and processing the system audio signal by using the latency value to obtain a second reference signal; performing de-noising processing on a collected second microphone signal according to the second reference signal, to obtain a to-be-recognized voice signal; and performing recognition on the to-be-recognized voice signal.
