Abstract

The embodiment of the invention provides a construction method and device for a speech synthesis model and a construction device for the speech synthesis model. The method comprises the following steps: selecting a data subset with complete phoneme coverage from multi-person voice data; and taking mixed data composed of single-person voice data of a target speaker and the data subset as training data, and performing adaptive training on a multi-person voice synthesis model by using the training data to obtain a single-person voice synthesis model of the target speaker. According to the embodiment of the invention, the problem of incomplete phoneme coverage of the single-person speech data of the target speaker can be solved, and the pronunciation accuracy of the single-person speech synthesis model of the target speaker obtained by final training can be improved.

Description

technical field [0001] The invention relates to the technical field of input methods, in particular to a method and device for constructing a speech synthesis model and a construction device for the speech synthesis model. Background technique [0002] With the development of deep learning, speech synthesis technology has entered the end-to-end development stage. The end-to-end speech synthesis model can directly output the speech corresponding to the text based on the input text. Speech synthesis technology is widely used in scenarios such as intelligent question answering and voice broadcasting. [0003] At present, it is possible to use a large number of speakers' voice data to train the speech synthesis model, and then use the speech data of a single speaker for adaptive training on the basis of the trained speech synthesis model to obtain the speech synthesis model of the target speaker's timbre. [0004] However, the amount of speech data of a single speaker is small...
