Abstract

The invention provides a speech synthesis method, device and equipment and a storage medium. The method comprises the steps that obtained text information is preprocessed through a speech synthesis device, and a text vector of the text information is obtained; the text vector is input into a preset acoustic model, and a first acoustic parameter vector corresponding to the text vector is obtained,wherein the acoustic model is used for processing the text vector according to a memory matrix to obtain the first acoustic parameter vector; speech information corresponding to the text message is synthesized according to the first acoustic parameter vector. Due to the fact that the memory matrix is updated continuously in the acoustic model, historical text information is memorized more effectively, the overall prediction effect of the acoustic model is improved, and then the output quality of the speech information is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular, to a speech synthesis method, device, equipment and storage medium. Background technique [0002] Speech synthesis and speech recognition technologies are two key technologies necessary to realize man-machine voice communication and establish a spoken language system capable of listening and speaking. Speech synthesis, also known as text-to-speech (Text to Speech) technology, can convert any text information into a standard and smooth voice in real time, which is equivalent to installing an artificial mouth on a machine. The goal of speech synthesis is to make the synthesized speech intelligible, clear, natural and expressive. [0003] Traditional speech synthesis methods are based on statistical learning and decision tree-based hidden Markov-Gaussian mixture model (HMM) and deep neural network model (DNN). The above model requires a large am...
