EmoInstruct-TTS: Dual-Path Instruction-Guided Emotional Speech Synthesis

arXiv:2606.20650v1 Announce Type: new Abstract: Instruction-based controllable speech synthesis enables users to specify emotions through natural language. However, existing approaches often rely on coarse emotion labels and lack explicit modeling of fine-grained intensity. We propose EmoInstruct-TTS, a dual-path instruction-guided framework for emotional speech synthesis. We introduce Emotion2embed, a supervised semantic-acoustic emotion embedding covering 48 emotional states, including fine-gr...
