Problems solved by technology

[0003] Due to the limited ability of the human ear to effectively identify mixed signals from different sound sources at the same time, usually the human ear can only recognize simultaneous speeches of less than 4 people. When the number of speakers reaches or exceeds 4 at the same time, the mixed sound The final sound is difficult to distinguish by the human ear, and the sound is messy and cannot be heard clearly

Abstract

The invention provides a voice coding control method and device, and a storage medium. Sound mixing processing is performed on call audios provided by each call terminal in a multi-person call scene to obtain a sound mixing result, the listening sense contribution degree of each call terminal to the sound mixing result is calculated, the target coding parameter of each call terminal is determinedaccording to the listening sense contribution degree, and the target coding parameter is returned to the corresponding call terminal. And each call terminal is enabled to adjust the current coding parameter according to the target coding parameter. According to the method, the coding parameters of each call terminal are dynamically adjusted based on the listening sense contribution degree of eachcall terminal to the mixed audio in the multi-person call scene, so that the subjective listening sense of the user is improved while the network bandwidth is saved.

Description

technical field [0001] The present invention relates to the technical field of voice communication, in particular to a voice coding control method, device and storage medium. Background technique [0002] Multi-person call means that multiple parties participating in the call perform audio signal collection and various audio processing through different devices (terminals), and then package them through voice coding and network transmission, and send them to the audio mixing device through the network, and the mixing device encodes the voice After the data is decoded, the sound is mixed and superimposed, and finally the terminals of each participant perform sound playback according to the corresponding mixed sound result signal. [0003] Due to the limited ability of the human ear to effectively identify mixed signals from different sound sources at the same time, usually the human ear can only recognize simultaneous speeches of less than 4 people. When the number of speaker...
