7.1 Upgraded Wav2Lip

The network structure of Wav2Lip has been upgraded and optimized; audio features are replaced with HuBERT; LSTM networks are introduced to establish correlation between preceding and subsequent frames.
192px and 384px models as well as integration code for LiveTalking are provided.

7.2 Digital Human Features

  1. Voice interaction: Supports synchronized subtitles and event notifications for the start and end of digital human speech; wake word interruption for ongoing speech is available.
  2. Vue-based client with transparent background support, enabling dynamic background switching for digital humans.
  3. Real-time audio stream input: Suitable for feeding real-time audio streams from external sources (e.g., audio-output large language models) to the digital human for live voice broadcast.
  4. Action switching: You can assign a specific action via the human API when triggering digital human speech, so the avatar performs the designated action while talking. Demo Video

Additional Exclusive Features:

  1. Python Client
    Features an independent video display window and Python interaction APIs, ideal for integration into Python projects such as live streaming workflows. Demo Video
  2. Multi-Avatar Concurrent Display
    Multiple digital humans can converse simultaneously within a single viewport. Each avatar’s speech and corresponding voice timbre can be designated via API. Demo Video
  3. Camera-Driven Avatar Motions & Expressions
    Streamers can make facial expressions and body movements in front of a camera without speaking; the API synchronizes lip movements to match the streamer’s facial gestures.
  4. LiveKit Integration
    Seamlessly embed digital humans into LiveKit rooms. Demo Video

7.3 Other Offerings

  1. Digital Human Management System
