Problems solved by technology

Since the ideal floating value masking does not take into account the phase information of the speech signal, the phase of the noisy speech cannot be corrected during the process of synthesizing the target speech, resulting in the inaccurate phase of the synthesized target speech. Therefore, this speech noise reduction method The lower voice distortion is greater, and the voice noise reduction effect is poor

Abstract

The embodiment of the invention discloses a voice processing method, a voice processing device and a device for processing voice. The embodiment of the method comprises the following steps of performing time-frequency analysis on noisy voice to obtain the frequency spectrum of the noisy voice in complex domains; inputting the frequency spectrum of the noisy voice in the complex fields into a pretrained time-frequency shielding prediction model; obtaining a prediction value of time-frequency masking of the noisy voice in the complex domains; multiplying the prediction value by the frequency spectrum of the noisy voice in the complex domains; generating the frequency spectrum of target voice in the noisy voice in the complex domains; and synthesizing the target voice on the basis of the frequency spectrum of the target voice in the complex domains. The embodiment has the advantages that the voice distortion degree is reduced, and the voice noise reduction effect is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a voice processing method, device and device for processing voice. Background technique [0002] With the development of computer technology, voice interaction products such as smart speakers and recording pens are becoming more and more abundant. Since voice interaction products receive noise and reverberation signals while receiving voice signals, in order to avoid affecting the voice recognition effect, it is usually necessary to extract the target voice from voices with noise and reverberation (such as relatively pure voice). [0003] Existing methods usually use the Ideal Ratio Mask (IRM) as the target, train a model for predicting the ideal Ratio Mask, and then use the model to obtain the predicted value of the ideal Ratio Mask for noisy speech, and then based on The predicted value obtains the masked acoustic feature, and then the masked...
