Speech synthesis device and speech synthesis method

Abstract

The invention discloses a speech synthesis device and a speech synthesis method. The speech synthesis device comprises a model building module, a receiving module, a style determining module, a model correcting module and an synthesis module, wherein the model building module is used for building a speech synthesis model in advance according to a great number of collected speaker speech data; the receiving module is used for receiving a text to be synthesized of a user; the style determining module is used for determining the synthesized speech style; the model correcting module is used for correcting the speech synthesis model according to the synthesized speech style so that the corrected speech synthesis model adapts to the synthesized speech style; and the synthesis module is used for using the corrected speech synthesis module for performing speech synthesis on the text to be synthesized to obtain the synthesis speech data. When the device and the method are used, the styles of the synthesis speech are rich and natural; the user experience is effectively improved; and the entertainment performance is enhanced.

Description

technical field [0001] The invention relates to the field of speech synthesis, in particular to a speech synthesis device and method. Background technique [0002] Speech synthesis, also known as text-to-speech conversion, its main function is to convert text into speech and make the synthesized speech as intelligible and natural as possible. With the increasing demand for speech synthesis, people have more and more diverse requirements for synthesized speech.
