About this model

Eleven Flash v2 is ElevenLabs' ultra-low-latency English text-to-speech model designed for real-time conversational applications, voice agents, interactive assistants, telephony, and other latency-sensitive speech workloads. It generates natural speech with under approximately 75 ms model inference latency and supports up to 30,000 characters of text per API request. The model prioritizes speed and responsiveness while maintaining natural vocal performance, making it particularly suitable for AI calling agents, customer-support systems, IVR applications, conversational AI, games, and other real-time voice experiences.
