Abstract

The invention discloses a method and a device for mobile terminal call voice noise reduction. The method comprises steps: time delay for data acquisition by two microphones of the mobile terminal is acquired; according to the calculated time delay, relative positions between the sound source of the mobile terminal user and the two microphones are determined; according to the determined relative positions, the microphone closer to the sound source is set to be the main microphone, and the other one is set to be the auxiliary microphone; and based on the determined main microphone and the auxiliary microphone, noise reduction processing is carried out on the call voice of the mobile terminal through a noise reduction algorithm. Due to the technical scheme of the invention, the sound quality of hands-free call voice receiving is improved in the condition of not increasing the design cost and the space of the mobile communication terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for reducing noise in conversation voice of a mobile terminal. Background technique [0002] Currently, mobile terminals are widely used and popularized. A voice call is a basic function of a mobile terminal, and the improvement of the sound quality of a voice call is a subject that all mobile terminals are devoted to researching. [0003] Due to the uncertainty and complexity of the call environment, environmental noise is an important factor affecting the voice quality of calls. Therefore, the noise reduction performance of mobile terminals has become a key indicator for major operators to evaluate mobile phones. How to eliminate or reduce environmental noise has also become a major issue for various Chip manufacturers and terminal manufacturers are committed to researching a key topic. [0004] For mobile terminals, noise reduction algorithms h...
