Abstract

The invention discloses a speech signal self-adaptive adjusting method, a speech signal self-adaptive adjusting device, a mobile terminal and a storage medium. The speech signal self-adaptive adjusting method comprises the steps of acquiring a speech signal in an environment in real time when the mobile terminal is in a hands-free calling mode, acquiring a distance between the mobile terminal and a caller in real time, analyzing the speech signal, acquiring vocal print features of sounds from different sources in the speech signal, identifying a target vocal print feature belonging to the caller, determining a speech amplitude value of the sound to which the target vocal print feature belongs in the speech signal, and adjusting a loudness degree and a frequency degree of the sound to which the target vocal print feature belongs according to the speech amplitude value and the distance. Through identifying the target vocal print feature of the caller in the speech signal, the sound of the caller can be adjusted according to the speech amplitude value of the sound to which the target vocal print feature belongs and the distance between the mobile terminal and the caller, thereby being capable of effectively avoiding the problem of amplifying environment noise, improving calling quality and improving use experience.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a voice signal adaptive adjustment method, device, mobile terminal and storage medium. Background technique [0002] At present, the application of mobile phones has become very common. The commonly used call modes of mobile phones include handheld call mode and hands-free call mode. The distance of the mobile phone will also have a great difference. When the mobile phone is radio, these differences will cause the volume of the voice signal collected by the mobile phone to be different, and the overall volume is relatively low. In order for the caller at the other end of the call to hear the call clearly, the collected voice signal needs to be amplified before being sent to the caller. [0003] In the prior art, in the hands-free call mode, the automatic gain control (Automatic GainControl, AGC) is used to adaptively adjust the gain to increase the volume of the...
