Title:
SPEECH SYNTHESIS METHOD AND APPARATUS, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/121176
Kind Code:
A1
Abstract:
A speech synthesis method, a speech synthesis apparatus (100), an electronic device (1), and a readable storage medium. The method comprises: acquiring a sample audio and performing sound feature extraction conversion and vectorization processing on the sample audio to obtain a standard voice vector (S1); when a text to be synthesized is received, performing phoneme conversion on said text to obtain a text phoneme sequence (S2); performing vector conversion on the text phoneme sequence to obtain a text matrix (S3); performing vector connection on the standard voice vector and the text matrix to obtain a target matrix (S4); performing spectral feature extraction on the target matrix to obtain spectral feature information (S5); and performing speech synthesis on the spectral feature information by using a preset vocoder to obtain a synthesized audio (S6). The present invention further relates to blockchain technology, and the spectral feature information can be stored in a blockchain. The flexibility of speech synthesis can be improved.
