AI-generated Answer for ayush_38869

Short answer:

eleven_v3 is the flagship Text-to-Speech (TTS) model for generating speech audio from text (including Text-to-Dialogue). It supports audio tags, 70+ languages, and is selected as model_id=eleven_v3 on the TTS endpoints. (elevenlabs.io)
eleven_ttv_v3 is a Text-to-Voice (TTV) “voice design” model used to generate new voices from a text prompt (or remix an existing designed voice). It is used on the Text-to-Voice endpoints (e.g., /text-to-voice/design and /text-to-voice/:voice_id/remix), not for direct TTS playback. (elevenlabs.io)

Key differences

Purpose
- eleven_v3: synthesize speech from text; also powers Text-to-Dialogue. (elevenlabs.io)
- eleven_ttv_v3: design/generate voice identities from prompts; outputs a generated_voice_id you can later use with TTS. (elevenlabs.io)
Endpoints
- eleven_v3: /v1/text-to-speech/:voice_id (Create/Stream speech), /v1/text-to-dialogue (Create/Stream dialogue). (elevenlabs.io)
- eleven_ttv_v3: /v1/text-to-voice/design and /v1/text-to-voice/:voice_id/remix. Some features are only supported with eleven_ttv_v3. (elevenlabs.io)
Model descriptions (from Models page)
- eleven_v3: “Human-like and expressive speech generation,” 70+ languages. (elevenlabs.io)
- eleven_ttv_v3: “Human-like and expressive voice design model (Text to Voice),” 70+ languages. (elevenlabs.io)
Extras for v3
- Audio tags and Dialogue mode are explicitly documented for Eleven v3. It is expressive but not aimed at real-time use. (help.elevenlabs.io)

In practice: use eleven_v3 when you want to generate spoken audio; use eleven_ttv_v3 when you want to create or remix a voice to then use in TTS. (elevenlabs.io)
