Abstract

The invention provides a speech signal processing method and a mobile terminal. The mobile terminal includes a microphone and a movable lifting module. The speech signal processing method includes the steps that when the microphone is turned on, if the movement of the lifting module is monitored, the mechanical noise reduction of first speech signals recorded by the microphone is carried out to obtain target speech signals; and mechanical noises include noises generated during the lifting module movement Therefore, according to the scheme of the speech signal processing method and the mobile terminal, the problem that the noises generated during the lifting module activity affects the auditory experience of the speech signals recorded by the microphone is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a voice signal processing method and a mobile terminal. Background technique [0002] With the advent of the era of full-screen mobile phones, in order to better the appearance, there are many solutions to realize full-screen on the market. Among them, there is a design in which the front camera is placed in a lifting module (pop-up block), or a design in which the receiver and camera are integrated in a lifting module. [0003] However, the lifting module is lifted and lowered by a motor, which will generate a lot of mechanical noise when the motor moves. Especially when the camera is switched during the video call, the microphone will record the mechanical sound of the motor, so when the user listens to the recorded speech signal, he will hear a loud noise, which brings some troubles to the user.
