Problems solved by technology

[0003] Embodiments of the present invention provide a method, device, mobile terminal, and storage medium for adaptive adjustment of earphone calls, which can solve the problem in the prior art that while improving the call volume through AGC adaptive gain adjustment, the entire voice signal will be affected. Both are amplified, which will inevitably amplify the environmental noise in the voice signal, which will lead to the problem of degrading the quality of the call

Abstract

An embodiment of the invention provides a self-adaptive adjustment method and device for earphone calls, a mobile terminal and a storage medium. The method comprises the steps as follows: when the mobile terminal is in an earphone call mode, a voice signal in the environment is acquired and analyzed, a target voiceprint feature is obtained through matching from analyzed voiceprint features by the aid of a preset voiceprint feature recognition library, the voice amplitude of the voice with the target voiceprint feature in the voice signal is determined, and the loudness value and the frequency value of the voice with the target voiceprint feature in the voice signal are adjusted according to the voice amplitude. Compared with an AGC (automatic gain control) self-adaptive gain adjustment method, the self-adaptive adjustment method has the advantages that the problem of ambient noise amplification can be solved effectively and the call quality can be improved while the call volume is increased.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for adaptive adjustment of earphone calls, a mobile terminal and a storage medium. Background technique [0002] At present, the application of mobile phones has become very common, and people are becoming more and more accustomed to using earphones for voice calls. Usually, people let the microphone hang down normally to make calls, but there is a problem of low call volume when using this method to make calls. In the prior art, the automatic gain control (Automatic Gain Control, AGC) is usually used to adaptively adjust the gain to increase the volume of the call. However, when the AGC adaptively adjusts the gain to increase the volume of the call, it will affect the entire voice signal. Both are amplified, which will inevitably amplify the environmental noise in the voice signal, which will lead to a decrease in the quality of the call. C...
