Hugging Face's Open TTS Leaderboard now includes a "streaming" tab benchmarking real-world TTS inference deployments. On H200, kyutai/pocket-tts (audio.cpp) leads with 12.4ms TTFA p50 (17ms p95) and RTFx 16.79. Qwen3-TTS-1.7B-CustomVoice implementations (audio.cpp, photon, GGUF) follow closely; Microsoft VibeVoice-1.5B, Breeze-TTS-2 and fishaudio/s2-pro also rank. Metrics cover TTFA p50/p95, RTFx and model size — useful for production streaming voice deployments.
