Prosody Modeling

An approach that models emphasis, rhythm, intonation, and pause structure to produce more natural speech synthesis.

Prosody modeling is one of the hardest and most decisive components of natural speech synthesis. The same text can convey very different meaning and impact depending on emphasis and intonation. Strong TTS systems therefore do more than pronounce the right words; they also attempt to generate the appropriate emotional and communicative flow. This directly affects user experience in education, media, and voice assistant applications.
