Abstract

The invention discloses a training method and device for a prosody model used for speech synthesis, wherein the training method for the prosody model used for speech synthesis comprises the following steps: S1, extracting textual features and marker features corresponding to participles from a training corpus text; S2, generalizing the participles in the training corpus text on the basis of Chinese thesaurus; S3, training the prosody model according to the textual features, the marker features and the generalized participles. According to the training method and device for the prosody model used for speech synthesis, by extracting the textual features and marker features corresponding to participles from the training corpus text, generalizing the participles in the training corpus text on the basis of Chinese thesaurus and then training the prosody model according to the textual features, the marker features and the generalized participles, the prosody model is more perfect, and further the prosody prediction accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of text-to-speech conversion, in particular to a prosody model training method and device for speech synthesis. Background technique [0002] Speech synthesis, also known as text-to-speech technology, is a technology that can convert text information into speech and read it aloud. With the continuous advancement of science and technology, the application of speech synthesis is becoming more and more extensive, such as news and information broadcasting, audio novels, etc. In daily life, text messages, emails and other information can also be synthesized into voice through speech synthesis, providing users with an additional way to obtain information. [0003] In the speech synthesis system, prosody prediction is the basis of the whole system, if the prosody pause prediction is wrong, it will directly affect the effect of speech synthesis. For example: the synthesized text is "if a passer-by handed it an emp...
