Title:
SPEECH SYNTHESIS METHOD AND APPARATUS, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/121157
Kind Code:
A1
Abstract:
A speech synthesis method, which relates to the field of artificial intelligence, and comprises: acquiring training text, and performing position vector encoding and sound spectrum encoding on the training text by using a pre-built speech synthesis model to generate a sound spectrum (S1, S2); performing pitch projection and duration projection of the sound spectrum to obtain a pitch spectrum and a duration spectrum, and performing residual connection between the pitch spectrum and the sound spectrum to generate a residual sound spectrum (S3); summarizing and smoothing the duration spectrum and the residual sound spectrum to obtain a target sound spectrum (S4, S5); calculating a loss value of the target sound spectrum and a corresponding label value, and adjusting parameters of the speech synthesis model according to the loss value to obtain a trained speech synthesis model (S6); and performing speech synthesis on speech text to be synthesized by using the trained speech synthesis model to obtain a synthesis result (S7). Blockchain technology is also involved. The target sound spectrum can be stored in a blockchain, which may improve the accuracy of speech synthesis.
