Abstract

The invention discloses a personalized speech synthesis model construction method and device, a speech synthesis method and device, and a personalized speech synthesis model test method and device. The construction method of the personalized speech synthesis model comprises the following steps: determining training data similar to a user from training set data of a plurality of speakers of a multi-speaker speech synthesis model; selecting similar speakers belonging to the same category as the user from the plurality of speakers except the speaker to which the approximate training data belongs; and training the multi-speaker speech synthesis model according to training data similar to the user and the selected similar speakers to obtain a personalized speech synthesis model of the user. The voice of the specific speaking style of the user can be synthesized, and the user experience is improved.

Description

technical field

[0001] The invention relates to the technical field of artificial intelligence, in particular to a construction method of a personalized speech synthesis model, a speech synthesis method, a testing method and a device. Background technique

[0002] Voice interaction scenarios in artificial intelligence technology require personalized voice synthesis. Personalized speech synthesis is a strong demand in business, and it is also one of the future trends in the field of speech synthesis.

[0003] In traditional speech synthesis technology, using hundreds of hours of training data from hundreds of speakers, a multi-speaker speech synthesis system based on massive data can be constructed. Specifically, a multi-speaker speech synthesis model can be used, for example, based on neural The text-to-speech (Neural TTS (Text-To-Speech)) model of the network, in the training data of this model, the voice data volume of a single speaker often ranges from a few hours to doz...
