Abstract

The invention relates to a voice enhancement method and device, and the method comprises the steps: calculating the voice existence probability of a current frame of audio signal, wherein the voice existence probability represents the existence probability of a voice signal in the current frame of audio signal; utilizing the voice existence probability to obtain a noise variance of a next frame ofaudio signal; and performing voice enhancement on the next frame of audio signal by using the noise variance of the next frame of audio signal. Voice enhancement is performed on the next frame of audio signal based on the voice existence probability so that the noise suppression level can be effectively enhanced and the loss of the voice signal can be reduced, the integrity and intelligibility ofthe voice signal after noise suppression can be guaranteed and the voice call quality can be enhanced.

Description

technical field [0001] The present disclosure relates to the technical field of speech processing, in particular to a speech enhancement method and device. Background technique [0002] During voice calls using mobile devices such as mobile phones in daily life, the speaker is often placed in a background environment full of various noises. The speech signal collected by the microphone is polluted by noise, that is, the uplink signal is a speech signal containing noise. If the uplink signal is not processed, it will be difficult for the far-end receiver to hear clear voice or even understand the meaning of the voice. Therefore, noise suppression must be performed on near-end noisy speech, and the clean speech after speech enhancement is used as an uplink signal to improve call quality. Contents of the invention [0003] In view of this, according to one aspect of the present disclosure, the present disclosure proposes a speech enhancement method, the method comprising: ...
