About this model

Eleven v4 is ElevenLabs' flagship text-to-speech model designed for highly expressive, emotionally rich, and natural speech generation. Built on a new speech synthesis architecture, it interprets tone, pacing, emotion, speaker identity, and conversational context to produce voice performances with greater realism and control. The model supports more than 90 languages, high-fidelity professional voice cloning, natural multi-speaker dialogue, and inline Audio Tags for controlling emotions, delivery styles, non-verbal expressions, and sound effects. It is optimized for premium content creation, character voiceovers, audiobooks, dubbing, narration, multilingual productions, and other applications where voice quality, expressiveness, and speaker consistency are prioritized.
