Expressive Speech Synthesis

A TTS approach focused on generating not only correct words but also appropriate style, tone, and emotional effect.

Expressive speech synthesis transforms TTS systems from mechanical reading engines into more human-like narrative tools. It is highly valuable for education, storytelling, media production, and personalized assistants. However, if expression generation is not controlled, inconsistency or unwanted tone may emerge. Style control and safe synthesis design therefore play a central role.
