Abstract
An embodiment of this application provides a speech processing method and apparatus, and an apparatus for speech processing, applied to a terminal device, where the terminal device is equipped with at least two microphones. The method includes: performing summation on signals received by the at least two microphones to obtain a first signal, and performing subtraction on the signals received by the at least two microphones to obtain a second signal; performing blind separation on the first signal and the second signal to obtain a speech signal and a noise signal; and performing adaptive noise cancellation on the speech signal based on the noise signal to obtain a target speech signal. The embodiments of this application can optimize a speech denoising effect, and further improve the speech recognition accuracy of the terminal device in a complex and changeable environment with large noise or strong interference.
