SPEECH SYNTHESIS METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2022/121158

A1

A speech synthesis method and a speech synthesis apparatus (100), and an electronic device (1) and a storage medium. The method comprises: obtaining a character vector, and performing attention calculation on the character vector by using a multi-head attention network to obtain an attention vector (S4); performing a residual connection on the attention vector and the character vector to obtain a character attention vector (S5); performing feature extraction on the character attention vector by using a character feature extraction network to obtain a character feature sequence (S6); and inputting the character vector into a pre-built pronunciation pause prediction model to obtain a pronunciation pause sequence (S7); performing a residual connection on the character feature sequence and the pronunciation pause sequence to obtain a speech sequence, and performing speech synthesis on the speech sequence by using a pre-built vocoder to obtain a synthesized speech of a character text (S8). The problem that the synthesized speech is not smooth and natural enough can be solved.
