Problems solved by technology

However, at present, there is no corresponding feasible solution for low-quality bit-rate speech reconstruction using software methods
For the reconstruction of low-quality bit-rate speech, the method of filling or interpolating data is usually adopted, but this method is too rough to restore the sound quality of high-quality speech

Abstract

The invention provides a deep-learning-based speech tone quality enhancement method, device and system. The method comprises: to-be-processed speech data are obtained and feature extraction is carriedout on the to-be-processed speech data to obtain features of the to-be-processed speech data; and on the basis of the features of the to-be-processed speech data, the to-be-processed speech data arereconstructed to be output speech data by using a trained speech reconstruction neural network, wherein the speech quality of the output speech data is higher than that of the to-be-processed speech data. According to the invention, the low-quality speech quality can be enhanced based on the deep learning method and the low-quality speech quality is reconstructed by the deep neural network to obtain the high-quality speech tone quality, so that the tone quality improvement effect that can not be realized by the traditional method is realized.

Description

technical field [0001] The present invention relates to the technical field of sound quality optimization, and more particularly to a method, device and system for enhancing speech sound quality based on deep learning. Background technique [0002] In recent years, voice wireless communication has developed rapidly and is currently widely used in various civil and industrial fields. The wireless communication is limited by the bandwidth, and it is required to compress the speech coding and reduce the sampling frequency and code rate of the speech as much as possible. Although speech coding reduces the speech quality, it also greatly saves resources. Early digital voice communication coding, such as Global System for Mobile Communications-Half Rate (GMS-HR), has a code rate of about 6.5kbps, adopts a sampling frequency of 8kHz, and has an actual bandwidth of less than 4k, which loses a lot of high-frequency information and makes the human voice lack The degree of recognitio...
