Abstract

The embodiment of the invention provides a voice reduction method and device, a mobile terminal, and a computer readable storage medium. The method is used for the mobile terminal, and the mobile terminal is connected with an earphone. The method comprises the steps: collecting a first audio signal; receiving a second audio signal transmitted by the earphone; detecting whether the mobile terminal is shaded or not; extracting a target noise signal from the first audio signal and / or the second audio signal based on a detection result; carrying out the noise reduction of a third audio signal obtained by the mobile terminal through the target noise signal, and outputting a fourth audio signal. The third audio signal is an audio signal collected by the earphone or an audio signal to be transmitted to the earphone. According to the embodiment of the invention, the method achieves a purpose of dynamically selecting a proper noise reduction scheme according to the environment, improves the noise pickup precision, and improves the noise reduction effect.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a voice noise reduction method, device, mobile terminal and computer-readable storage medium. Background technique [0002] With the development of science and technology, mobile terminals have become an indispensable communication tool and entertainment tool in people's lives. Usually, earphones can be connected to mobile terminals, and the earphones can be used to make calls, play music, etc. There are many public places, such as public transportation stations such as buses, subways, and airports, and the loud noise in the surrounding environment will affect the use of headphones. [0003] In the prior art, by adding a customized sound processing chip, the sound processing chip can generate noise reduction waves after collecting noise in the surrounding environment. When using earphones for calls, playing music, etc., adding noise reduction waves can Noise cance...
