About this model

Eleven v4 Turbo is ElevenLabs' real-time text-to-speech model designed for conversational voice agents, AI assistants, interactive characters, and other latency-sensitive speech applications. It combines the expressive range and voice fidelity of the Eleven v4 family with approximately 100 ms median inference latency and around 150 ms median time to first speech. The model supports more than 90 languages and accents, high-fidelity voice cloning, expressive Audio Tags, pronunciation control, multilingual voice consistency, and streaming speech generation. It is optimized for natural long-running conversations where emotional expression, speaker consistency, responsiveness, and low latency are important.
