Developer API platform for production-ready speech, transcription, music, agents, and audio generation.
ElevenLabs API exposes nine distinct audio AI models through a unified REST interface: text-to-speech with sub-500ms streaming latency, speech-to-text at 20–50x real time, voice cloning from a library of over 10,000 voices, music generation, sound effect synthesis, dubbing with multi-language translation, conversational voice agents with phone integration, audio isolation, and forced alignment returning word-level timestamps. Official SDKs cover Python, TypeScript/JavaScript, Flutter, Swift, and Kotlin, and every endpoint supports streaming output.
Billing is usage-based: text-to-speech is charged per character, speech-to-text per audio minute, and music and sound effects per generation; all API-generated content carries a commercial license, with music requiring separate licensing for advertising, film, and enterprise distribution. Customers including Meta, Stripe, Perplexity, Chess.com, and Twilio use the platform at scale. Enterprise tiers add dedicated SLAs, SOC 2 compliance, single sign-on, and deployment assistance.
