Abstract: An electronic device obtains audio signals collected by different microphones in a microphone array. The device filters the audio signals using a first filter to obtain a first target beam. The first filter is configured to suppress an interference speech in the audio signals and enhance a target speech in the audio signals. The device filters the audio signals using a second filter to obtain a first interference beam. The second filter is configured to suppress the target speech and enhance the interference speech. The device a second interference beam of the first interference beam using a third filter. The device determines a difference between the first target beam and the second interference beam as a first audio processing output. The device adaptively updates at least one of the second filter and the third filter, and updates the first filter according to the updated second filter and/or third filter.

Abstract: A voice signal processing method and apparatus, which are used to process a voice signal collected by a microphone of a terminal in order to meet requirements of the terminal in different application modes for the voice signal generated after the processing. The method includes collecting at least two voice signals, determining a current application mode of a terminal, determining, according to the current application mode from the voice signals, voice signals corresponding to the current application mode, and performing, in a preset voice signal processing manner that matches the current application mode, beamforming processing on the corresponding voice signals.
