Problems solved by technology

At present, some widely popular singing speech synthesis methods still use context-dependent hidden Markov models, but these models face serious over-smoothing effects, and the ability to model statistical parameters is limited, so the generated singing speech is not as good as the timbre. Compared with the naturalness, the real singing effect is greatly reduced

Abstract

The invention discloses a singing voice synthesis method and a synthesis device, and a computer storage medium. The synthesis method comprises the following steps: acquiring music score information; performing feature extraction on the music score information to obtain music score features; performing fundamental frequency feature prediction on the music score features to obtain fundamental frequency features; performing acoustic feature prediction on the music score features in combination with the fundamental frequency features to obtain acoustic features; and obtaining synthesized singing voice data according to the acoustic characteristics. According to the synthesis method provided by the invention, the accuracy and naturalness of singing speech synthesis can be improved.

Description

technical field [0001] The present application relates to the technical field of speech synthesis, in particular to a singing speech synthesis method, a synthesis device, and a computer storage medium. Background technique [0002] Text To Speech (TTS) is a technology that converts text into speech. In recent years, due to the development of tools such as deep learning, great progress has been made and it has been widely used, which has led to Singing Voice Synthesis (SVS) ) has received more attention and has gradually become one of the important functions of virtual idols, voice assistants and many smart devices. At the same time, singing speech synthesis can be easily combined with other artificial intelligence technologies, such as machine composition, automatic lyrics, etc., forming a broad application space. With the advancement of multimodal technology, artificial intelligence singers are becoming more and more popular with the public. [0003] Research on computer-...
