ElevenLabs is an American software company that specializes in AI-assisted voice generation, including text-to-speech (TTS) and speech-to-speech (STS) synthesis. ElevenLabs’ software uses advanced machine learning models to generate realistic-sounding audio from written text or from one voice to another.
