ISCSLP 2026 CoT-TTS Challenge Results
Final scores combine objective evaluation, LLM-based reasoning assessment, and human listening tests. All component scores are mapped to a unified 0-5 scale where higher is better.
Scoring Formula
Final = 0.3 Objective + 0.2 LLM + 0.5 Human
Objective scores summarize automatic speech metrics, LLM scores evaluate reasoning quality, and human scores measure perceived contextual appropriateness, emotion, and audio quality.
