Abstract

The invention discloses a speech synthesis method, a related device, equipment and a storage medium, and the method comprises the steps: extracting a plurality of frame-level acoustic features based on a to-be-synthesized text; performing prediction based on each frame-level acoustic feature to obtain an acoustic parameter corresponding to each frame-level acoustic feature; based on the excitation parameter, the noise parameter and the acoustic parameter corresponding to the frame-level acoustic feature, performing fusion to obtain a frequency spectrum value corresponding to the frame-level acoustic feature; and based on the frequency spectrum value corresponding to each frame-level acoustic feature, obtaining a synthetic speech. According to the scheme, the speech synthesis efficiency and quality can be improved.

Description

technical field [0001] The present application relates to the technical field of speech synthesis, in particular to a speech synthesis method and related devices, equipment and storage media. Background technique [0002] Speech synthesis is a method of converting text into speech, mainly including front-end, acoustic model and vocoder. The vocoder is a method of converting speech features such as spectrum into speech, and is an important part of the speech synthesis system. In recent years, with the continuous development of technology, neural network vocoders with high naturalness and high sound quality have appeared one after another, but these vocoders often have a large amount of calculation and the synthesis speed is not ideal. Although the vocoder based on traditional signal processing has a fast synthesis speed, the sound quality is not high. In view of this, under the premise of ensuring the naturalness and sound quality of speech synthesis, how to realize an effi...
