Problems solved by technology

[0003] Usually in the hands-free call mode of the mobile terminal, the microphone that is arranged next to the speaker at the bottom of the mobile terminal is used as the secondary input, and the microphone that is arranged on the top of the mobile terminal or near the camera on the back is used as the main input, but In the hands-free mode, this way of setting the main and secondary microphones will cause the upstream voice quality after the microphone noise reduction processing is not high

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0022] Generally, in order to eliminate environmental noise during a voice call, a mobile terminal is provided with two or more microphones for microphone noise reduction processing. During a call, the mobile terminal will cancel and filter the voice signals collected by two or more microphones to achieve the purpose of reducing environmental noise. In the specific microphone noise reduction process, the mobile terminal will use the voice signal collected by one microphone as the main input...

Abstract

The embodiment of the invention discloses a voice signal processing method and device and a mobile terminal. The method comprises the steps that a first voice signal received by a main microphone within the current first time period and a second voice signal received by a secondary microphone within the current first time period are obtained, wherein in the first time period, the mobile terminal is in a hands-free call state and no downlink voice signals are detected; the one, which is higher in intensity, in the first and second voice signals is used as a main input signal which is output inthe current first time period and used for noise reduction of the microphones, and the one, which is lower in intensity, in the first and second voice signals is used as a secondary input signal whichis output in the current first time period and used for noise reduction of the microphones. By means of the method, when a user speaks into any one microphone, and uplink voice signals obtained afternoise reduction of the microphones can be high in intensity, so that the quality of the uplink voice signals is improved while the noise reduction effect on the microphones is ensured.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a voice signal processing method, device and mobile terminal. Background technique [0002] In order to eliminate the noise in the environment collected by the mobile terminal during the sound collection process, the mobile terminal is usually provided with dual microphones or even multiple microphones for microphone noise reduction processing. In the case of dual microphones, one microphone is the main input microphone, and the other microphone is the secondary input microphone. In the microphone noise reduction process, the mobile terminal will combine the sound signal collected by the secondary input microphone with the The sound signals collected by the main input microphones are mutually filtered to filter noises in the sound signals collected by the main microphone, and then the filtered sound signals collected by the main microphone are used as uplink ...
