Abstract

Embodiments of the present disclosure provide a speech synthesis processing method, device, device, and storage medium. The method includes: acquiring original speech data of a target speaker; a source speaker; extracting a first speech feature of the target speaker according to the original speech data, and obtaining a second speech feature corresponding to the first source speaker and the original speech data; based on the first The speech features and the second speech features are optimized for training the preset speech conversion model to obtain a target speech conversion model; based on the target speech conversion model, a speech broadcast service is provided for the user. It realizes that the required speech conversion model can be obtained simply and quickly based on a small amount of speech data, and solves the defects of low accuracy of the speech conversion model obtained in the prior art if there is only a small amount of speech data of the target speaker.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a speech synthesis processing method, device, equipment and storage medium. Background technique [0002] With the development of speech synthesis technology, it is gradually widely used in people's daily life. For example, in the field of transportation, users will use navigation broadcasts during driving. In order to increase user interest and improve user experience, users can be provided with speech synthesis broadcast services. [0003] In the prior art, a large amount of high-quality speech data is usually required to train a speech conversion model to provide users with speech synthesis and broadcast services. In reality, users often cannot provide speech data that meets the requirements, resulting in low performance of the obtained speech conversion model and inaccurate speech conversion. Contents of the invention [0004] Embodiments of the present dis...
