LemonSlice

ChatGPT plugin

Video avatar for voice agents

View in ChatGPT directory

LemonSlice turns any single image into a real-time, lip-synced video avatar that joins your LiveKit room as a participant. This plugin teaches ChatGPT and Codex to attach the avatar to an existing LiveKit agent in Python or Node.js, or to scaffold a complete app from the LemonSlice starter: API keys, the voice cascade, the ringing UI, and optionally CWM-1 so the character reacts and emotes during the call.

    Add a LemonSlice video avatar to a LiveKit Agents app, or build one from scratch. LemonSlice turns any single image into a real-time, lip-synced talking avatar that joins the LiveKit room as a participant. Use when: (1) the user wants a talking avatar, a face on a voice agent, a lip-synced character, or a video agent on LiveKit — even if they do not name LemonSlice; (2) they mention lemonslice.AvatarSession, livekit-agents[lemonslice], @livekit/agents-plugin-lemonslice, or the lemonslice-examples repo; (3) they want the avatar to move and emote on its own or on cue (CWM-1, Character World Model, emotion engine, waving, smiling, laughing, leaning in), or to change its image or demeanor mid-call (update-image); (4) they are moving from another LiveKit avatar plugin (Tavus, HeyGen, Hedra, Beyond Presence, Anam, Synthesia); (5) the avatar never shows up, shows a black frame, drops after a fixed number of minutes, or the audio doubles. Works for Python and Node.js agents.
