About this model

Eleven Flash v2.5 is ElevenLabs' ultra-low-latency multilingual text-to-speech model designed for real-time voice agents, conversational AI, interactive applications, telephony, and large-scale speech generation. It generates high-quality natural speech with approximately 75 ms model inference latency while supporting 32 languages and up to 40,000 characters per request. The model balances speech quality, speed, and cost for latency-sensitive production workloads and supports streaming generation, voice cloning, multilingual voice consistency, and multiple audio output formats. It is particularly suited for AI calling agents, customer support systems, chatbots, games, IVR applications, and other real-time experiences where fast time-to-speech is critical.
