Patent ID: 10825444

Abstract:
The present disclosure provides a speech synthesis method and apparatus, a computer device and a readable medium. The method comprises: when problematic speech appears in speech splicing and synthesis, predicting a time length of a state of each phoneme corresponding to a target text corresponding to the problematic speech and a base frequency of each frame, according to pre-trained time length predicting model and base frequency predicting model; according to the time length of the state of each phoneme corresponding to the target text and the base frequency of each frame, using a pre-trained speech synthesis model to synthesize speech corresponding to the target text; wherein the time length predicting model, the base frequency predicting model and the speech synthesis model are all obtained by training based on a speech library resulting from speech splicing and synthesis. The technical solution of the present disclosure may avoid complementarily recording language materials and re-building a library, effectively shorten the time for repair of the problematic speech, and save the repair costs of the problematic problem; it may be ensured that naturalness and continuity of the synthesized speech is improved, and the sound quality of the speech synthesized by the model, as compared with the sound quality of the speech resulting from the splicing and synthesis, does not change and does not affect the user's listening feeling.
