Abstract

One or more embodiments of the invention provide a voice data processing method and device, equipment and a storage medium. The method comprises the following steps: acquiring to-be-processed voice data; randomly selecting a target voice processing operation from preset voice data processing operations, wherein each preset voice data processing operation comprises time domain masking, frequency domain masking, pitch conversion, volume conversion and audio noise addition; acquiring a value range corresponding to a voice processing parameter of the target voice processing operation, and randomly selecting a parameter value of the voice processing parameter of the target voice processing operation in the value range; and processing the to-be-processed voice data by using the target voice processing operation based on the parameter value. Through the embodiment of the invention, the problems of a complex expansion process and high expansion cost when the data volume of a training sample of a speech recognition model is expanded at present can be solved.

Description

technical field [0001] This document relates to the technical field of data processing, in particular to a voice data processing method, apparatus, device and storage medium. Background technique [0002] Speech recognition technology is an important research direction in the field of artificial intelligence. Speech recognition technology mainly converts speech into text through various speech recognition models such as ASR (Automatic Speech Recognition) models. No matter which speech recognition model is aimed at, the data volume of training samples is always the basis of model training. The larger the data volume of the training samples, the more accurate the speech recognition model obtained by training. In the prior art, the data volume of the training samples is expanded through a model. For example, a neural network model is trained, the speech data to be processed is processed through the neural network model, and the processed speech data is used as a training sam...
