New framework enables multi-emotion control in text-to-speech systems

By PulseAugur Editorial · [1 sources] ·

Researchers have developed HybridEmo, a novel framework for training Text-to-Speech (TTS) systems capable of handling multiple emotions within a single utterance. This framework addresses limitations in current multi-emotion TTS by employing Group Relative Policy Optimization with a sample-aware hybrid reward. HybridEmo demonstrates significant improvements in controlling emotion trajectories and blending emotions, outperforming existing models like CosyVoice 3 and EmoVoice-0.5B in human evaluations. AI

IMPACT Enables more nuanced and expressive synthetic speech, potentially improving virtual assistants and content creation tools.

    Sequential Trajectories and Simultaneous Blending: Multi-Emotion Modeling for Instruction-Following TTS

    arXiv:2608.30325v1 Announce Type: new Abstract: Natural-language instructions enable flexible control of synthesized speech, yet emotional TTS systems primarily model a single utterance-level affect, leaving multi-emotion control underexplored. We study two complementary multi-em…
