Abstract

The invention relates to a speech recognition and model training method, a device and a computer readable storage medium. The method comprises the steps: obtaining a first loss function of a speech separation enhancement model and a second loss function of a speech recognition model; performing back propagation based on the second loss function to train an intermediate model bridged between the speech separation enhancement model and the speech recognition model to obtain a robust representation model; fusing the first loss function and the second loss function to obtain a target loss function; and performing joint training on the speech separation enhancement model, the robust representation model and the speech recognition model based on the target loss function, and ending the trainingwhen a preset convergence condition is satisfied. According to the scheme provided by the invention, the speech recognition accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of speech processing, in particular to a speech recognition and model training method, device and computer-readable storage medium. Background technique [0002] The development of speech recognition technology has made it possible for humans and machines to interact through natural language. Speech signals can be converted into text sequences based on speech recognition technology. To achieve this conversion, it is necessary to perform front-end processing such as Speech Separation (SS) and Speech Enhancement (Speech Enhancement, SE) on the picked up speech signal, and then perform automatic speech recognition (Automatic Speech Recognition, ASR) on the acoustic features obtained by the front-end processing. ) backend processing. [0003] In the traditional way, the front-end speech separation enhancement model and the back-end speech recognition model are trained independently, and the speech se...
