Where is the face rendered?

Video avatar APIs (HeyGen LiveAvatar, Anam, Lemon Slice and others) render the face on their servers and stream it as video, usually billed per minute. In-browser SDKs (Talking Avatar, Mascot Bot, TalkingHead) animate on the user's device, with no video stream.

2D or 3D?

Rive and Live2D suit flat, cartoon mascots. three.js libraries like Talking Avatar and TalkingHead animate 3D .glb models. Video APIs produce photoreal faces.

What does lip sync need?

Text-driven lip sync needs word or phoneme timings from your TTS. Audio-only lip sync works with any voice, including live voice agents that only give you an audio stream.
