How it works

Control Center configures and launches the runtime. Everything else is automatic.

NPSC architecture: Control Center to Player Runtime to ElevenLabs and your game engine

Everything in one app

No pipeline to assemble. One installer, fully local, no coding required.

Voice input

Push-to-talk or hands-free with echo cancellation. External audio input over UDP for engine-managed mics.

Neural lipsync

GPU-accelerated model generates ARKit blendshapes locally. CPU fallback included. No cloud round trips.

LiveLink at 60 fps

ARKit blendshapes streamed over LiveLink to MetaHuman or any compatible rig in Unreal Engine or Unity.

Multilingual

Multiple languages out of the box. Runtime switching, auto-detect, and timeout phrases per language.

Game integration

Two-way UDP messaging. Topic routing, event triggers, animation states sent to your engine in real time.

Control Center

Full GUI for API keys, voice settings, face tuning, network config, and live session logs.
