Title:
SPEECH SYNTHESIS METHOD AND APPARATUS, SYNTHESIS MODEL TRAINING METHOD AND APPARATUS, MEDIUM, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/151931
Kind Code:
A1
Abstract:
A speech synthesis method and apparatus (600), a synthesis model training method and apparatus (700), a medium, and a device (800). The speech synthesis method comprises: obtaining speech feature information corresponding to text to be synthesized (S101); inputting the speech feature information into a speech synthesis model to obtain predicted waveform point information corresponding to said text (S102), the speech synthesis model comprising an acoustic submodel and a vocoder, and the speech synthesis model being obtained by directly performing joint training on the acoustic submodel and the vocoder; and performing μ-law expansion on the predicted waveform point information to obtain audio information (S103). By this way, the efficiency of speech synthesis can be improved, the error accumulation in related art generated by training an acoustic submodel and a vocoder separately is effectively reduced, and the accuracy of speech synthesis is improved. In addition, the problem that generated audio information cannot adapt to special pronunciation requirements due to the fact that acoustic features do not have universality can also be avoided, and the speech synthesis effect is improved. Additionally, a training period of models is short, and the rhythm fidelity of the models is better.
