Abstract

The invention provides a voice signal processing method and device. The method comprises the steps that the relative positional relation between a user and an electronic device is obtained; a first distance between a voice source of voice signals to be collected and the electronic device is determined according to the relative positional relation; adjusting signal intensity compensating parameters of the voice signals in the voice signals collected by a voice collecting unit according to the first distance. According to the voice signal processing method, the quality of the voice signals output by the electronic device can be improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, and more specifically relates to a voice signal processing method and device. Background technique [0002] When people use the electronic device to make a call, it is often necessary to turn on the hands-free mode on the electronic device, so that other things can be processed while talking. When the electronic device is in the hands-free call mode, if the background noise where the electronic device is located is relatively large, the microphone of the electronic device will also collect a relatively large near-end noise signal while collecting a far-end user voice signal. In this way, since the sound signal will gradually attenuate with the increase of the distance, the intensity of the collected near-end noise signal is much larger than the intensity of the far-end voice signal, so that the intensity of the voice signal is greatly weakened , thereby reducing the commun...
