ElevenLabs Turbo v2.5 is a text-to-speech model positioned in the middle of ElevenLabs' speed-versus-quality lineup, aimed at interactive applications such as voice agents and conversational systems where responsiveness matters. The company describes typical latency around 250-300ms and support for 32 languages, with a per-request limit of 40,000 characters. It is API-only and proprietary.
