MuseTalk

MuseTalk is the higher-quality video-avatar lip-sync path in OpenTalking. Compared with Wav2Lip, it has heavier dependencies and preprocessing; compared with QuickTalk, it is more quality-oriented and useful when you already have a MuseTalk runtime. This page explains when to choose MuseTalk and which deployment mode to use.

Support Status

Item Value
Model ID musetalk
Backend local / omnirt / direct_ws
Evidence level Local adapter is wired; local mode runs official MuseTalk preprocessing before session initialization
Best for Higher-quality lip sync, video avatars, existing MuseTalk runtimes

Benchmark Reference

The numbers below are summarized from Benchmark. Steady FPS is model-generation throughput, not full user-perceived latency; STT, LLM, TTS, queueing, and WebRTC still affect the complete experience.

Hardware Backend Output Steady FPS First-turn total/ms TTFV/ms Peak inference VRAM/GB
RTX 3090 OmniRT 512×512 / 25fps 28.868 3235.518 1769.484 5.078

When to Choose Another Model

  • Need the lightest real lip-sync validation: see Wav2Lip.
  • Need lower-latency realtime speaking: see QuickTalk.
  • Need a high-quality heavyweight service path: see FlashTalk.
