Speech Generation

About this leaderboard

Benchmarks TTS models for intelligibility, natural prosody, speaker similarity, noise robustness, latency, and hallucination-free rendering across multiple voices and languages.

We stress-test models with curated simulations that blend structured benchmarks and open-ended prompts. Each table captures a distinct slice of the use case, and models are compared consistently across shared metrics to surface leaders, trade-offs, and surprising strengths.
