ElevenLabs offers an AI text-to-speech platform that converts written text into natural-sounding spoken audio across 70+ languages using deep learning voice models. Users can generate speech using pre-built voices, cloned voices, or custom-designed voices via a web platform or API.

The platform's core text-to-speech system takes written text as input and produces audio files with realistic intonation, emotion, and pacing as output. ElevenLabs' models are trained to interpret contextual aspects of text, detecting emotional cues such as anger, sadness, or happiness, to adjust delivery accordingly. The Eleven v3 model, which reached general availability in March 2026, added inline audio tags and a Text to Dialogue API for multi-speaker generation, enabling voices that sigh, whisper, laugh, and react within a single output.
