Fish Audio Releases Drama 3, a 35B Open-Weight MoE Text-to-Speech Model

Fish Audio has released Drama 3, a 35-billion-parameter open-weight Mixture-of-Experts text-to-speech model, making one of the largest openly available TTS models accessible to developers and researchers. Open-weight TTS at this scale is unusual — most high-quality speech synthesis models at this parameter count are proprietary or API-only, so this release meaningfully expands what developers can self-host or fine-tune. The MoE architecture keeps inference costs manageable relative to a dense 35B model, which is critical for real-time or near-real-time voice applications. Developers building voice agents, accessibility tools, or multilingual applications now have a high-capacity open alternative to commercial TTS APIs. The release should be evaluated against existing options like ElevenLabs and OpenAI TTS for quality, latency, and fine-tuning flexibility.
