Abstract

An embodiment of the invention provides an adaptive voice enhancing method and electronic equipment. The adaptive voice enhancing method comprises the steps of after a voice signal is received, according to the voice signal, calculating the power of the current frame of the voice signal (101); comparing the power of the current frame with the noise power of a previous frame (102); according to a comparison result and the noise power of the previous frame, obtaining the noise estimated value of the current frame (103); and according to the noise estimated value, acquiring a pure voice signal (104). The adaptive voice enhancing method and the electronic equipment have advantages of realizing more accurate noise estimation, reducing algorithm complexity, facilitating voice signal enhancement,and improving heating perception quality of the people.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to an adaptive speech enhancement method and electronic equipment. Background technique [0002] In real life, because the speaker is often in various noisy environments, the speech signal will inevitably be polluted by background noise, and the background noise will make the performance of many speech processing systems drop sharply. As a signal processing method, speech enhancement is an efficient way to solve noise pollution. On the one hand, speech enhancement can improve the clarity, intelligibility and comfort of speech in a noisy environment, and improve the quality of human auditory perception; on the other hand, speech enhancement is also an essential link in speech processing systems. Before performing various voice signal processing operations, voice enhancement must be performed first to reduce the impact of noise on the voice processing system ...
