Abstract

An embodiment of the invention provides a voice enhancement processing method and device. The method includes: decoding bit streams, and obtaining coding parameters of a current voice subframe to be processed, the coding parameters including first generation digital book gains and first self-adaptive code book gains; adjusting the first generation digital book gains, and obtaining second generation digital book gains; determining second self-adaptive code book gains according to the first self-adaptive code book gains and the second generation digital book gains; and adopting quantization indexes of the second generation digital book gains and the second self-adaptive code book gains to replace bits corresponding to the first generation digital book gains and the first self-adaptive code book gains. By adoption of the technical scheme of the invention, an effect of eliminating noise can be effectively improved, and voice communication quality can be improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a voice enhancement processing method and device. Background technique [0002] The purpose of speech enhancement is to compress background noise from noisy speech signals, extract pure speech, and improve call quality. In general, the speech enhancement algorithm is usually located in the terminal equipment of the mobile communication network, and its position is before the speech coding or after the speech decoder, but due to the limitation of power consumption, storage space and cost, the speech enhancement algorithm in the terminal equipment usually cannot To achieve a good enhancement effect, the performance of the algorithm cannot meet the increasing demand. Therefore, more and more researchers and communication operators believe that the voice enhancement algorithm working in network equipment is a feasible solution. Linear domain speech enhancement ...
