Training method and device of voice processing model, voice recognition method, system and device

Abstract

The application provides a training method and device of a voice processing model, a voice recognition method, system and device, and relates to the technical field of information related to artificial intelligence and machine learning. The training method of the voice processing model comprises the following steps of performing iterative joint training on a voice enhancement model, a voice recognition model and a voice discrimination model; for each training, obtaining a joint loss function of the voice enhancement model, the voice recognition model and the voice discrimination model, and a voice discrimination loss function of the voice discrimination model; and adjusting model parameters of the voice enhancement model and / or the voice recognition model according to the joint function after each training, and adjusting the model parameter of the voice discrimination model according to the voice discrimination loss function, and the trained voice processing model is acquired until thejoint loss function and the voice discrimination loss function simultaneously satisfy a convergence condition. The robustness of the voice processing model is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular, to a training method for a speech processing model, a speech recognition method, system and device. Background technique [0002] With the development of communication technology and the popularization of smart terminals, various network communication tools have become one of the main tools for public communication. Among them, due to the convenience of operation and transmission of voice information, it has become the main transmission information of various network communication tools. When using various network communication tools, it also involves the process of converting voice information into text, which is the voice recognition technology. [0003] Speech recognition technology is a technology that enables machines to convert voice information into corresponding text or commands through the process of recognition and understanding.

Problems solved by technology

[0004] The speech enhancement processing method in the prior art is usually to design a filter to perform speech enhancement, but the filter in the prior art usually assumes that the acoustic environment is stable, ignoring the uncertainty of the acoustic environment in the real scene, Therefore, it cannot be applied to scenes with poor acoustic environment stability, and the robustness is low.
