# ElevenLabs

> AI text-to-speech platform producing natural-sounding voice audio with voice cloning, multilingual support, and emotional expression control.

AI text-to-speech platform producing natural-sounding voice audio with voice cloning, multilingual support, and emotional expression control. Best for workflows needing high-quality voice synthesis — narration, accessibility features, and voice-enabled applications. The leading TTS provider for naturalness — unlike Soniox (speech-to-text), ElevenLabs converts text to speech with human-like intonation.

7 endpoints available through Lava's AI Gateway. See the [ElevenLabs API docs](https://elevenlabs.io/docs/api-reference) for full documentation.

<Info>Supports both **managed** (Lava's API keys) and **unmanaged** (bring your own credentials) mode.</Info>
