New TTS system EmoTra-TTS mimics natural emotion transitions in speech

By PulseAugur Editorial · [1 sources] ·

Researchers have developed EmoTra-TTS, a novel text-to-speech system designed to mimic the natural, continuous evolution of emotions within a single utterance. Unlike existing systems that use static emotion labels, EmoTra-TTS employs a multi-pass flow blending pipeline and dual-stage Valence-Arousal-Dominance conditioning to achieve precise, controllable intra-utterance emotion transitions. This approach reportedly improves emotion transition quality by up to 87% and shows significant win rates in user preference tests against state-of-the-art and commercial systems, with minimal addition to model parameters and no latency overhead. AI

IMPACT Enhances naturalness and expressiveness in speech synthesis, potentially improving human-computer interaction and accessibility.

    EmoTra-TTS: Smooth Intra-Utterance Emotion Transitions for Speech Synthesis

    arXiv:2608.23791v1 Announce Type: cross Abstract: Psychological research on emotion dynamics has established that human affect is a continuous, evolving process: emotions rise, decay, and transition within seconds. Current emotional text-to-speech (TTS) systems, however, conditio…
