Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] One of the core concepts of the embodiments of the present invention is to train multiple teacher models in advance using different sub-bands of the speech spectrum, and use multiple teacher models to guide the training of a student model, so that the student model can learn the different sub-bands. features; and then use the student model for speech enhancement, which can achieve a better speech enhancement effect; thus, the speech enhancement effect of the model can be improved without increasing the parameter amount and calculation cost of the speech enhancement model.

[0036] The following first describes how to train the student model.

[0037] refer to figure 1 , which shows a flow chart of the steps of an embodimen...

Abstract

The embodiment of the invention provides a model training and voice enhancement method and device and electronic equipment, and the method comprises the steps: obtaining voice data; performing voice enhancement on the voice data according to a preset voice enhancement model, the preset voice enhancement model being a student model guided and trained by a teacher model, and the teacher model comprising a plurality of models trained based on different sub-bands of a voice spectrum, further, the student model can learn features on different sub-bands; therefore, a better speech enhancement effect can be achieved, and the speech enhancement effect of the model is improved on the premise that the parameter quantity and the calculation cost of the speech enhancement model are not increased.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a speech enhancement and model training method, device and electronic equipment. Background technique [0002] With the rapid development of communication technology, terminals such as mobile phones and tablet computers are becoming more and more popular, which brings great convenience to people's life, study and work. Users usually use the terminal to input voice commands to perform voice photography, voice search, etc.; also use the terminal to play voice data (such as music, video, recording). Among them, in order to enable the terminal to better execute the user's voice commands and play voice data with higher quality, the terminal can use voice enhancement technology to suppress and reduce noise interference in voice data after collecting voice commands or before playing voice data, Extract useful speech data from noisy background. [0003] At present, the method o...
