Abstract

The embodiment of the invention discloses a method and device for restraining noise, an electronic device and a computer readable storage medium. The method includes the steps that in the process of communication, the working state of a telephone receiver of the electronic device is determined, if the telephone receiver is in an idle state, a first voice signal is collected through the telephone receiver, microphones of the electronic device are used for collecting a second voice signal, and the second voice signal is subjected to noise reduction processing based on the first voice signal. Compared with the prior art, the telephone receiver in the idle state is utilized for collecting the first voice signal, furthermore, the first voice signal is utilized for performing noise reduction onthe second voice signal collected through the microphones, the noise-reduction processes of the two microphones can be simulated, a noise signal in the second voice signal is effectively restrained, and communication quality is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a noise suppression method and device, an electronic device and a computer-readable storage medium. Background technique [0002] A microphone (Microphone, Mic) is a widely used electro-acoustic transducer device, which can convert voice signals into corresponding electrical signals. The electric signal is an analog signal with continuous changes of specific frequency, amplitude and phase, which can reflect the characteristics of the voice signal. [0003] In the process of collecting voice signals, the microphone collects the overall sound signal of the surrounding environment, and cannot collect specific sounds. Therefore, when applied to wireless calls or other real-time call devices, it usually collects multiple noises mixed in the surrounding environment at the same time, causing the user's real voice to be covered and affecting call quality.
