- Only act when speaking, with semantic coordination.
- It can switch videos seamlessly without any flickering.
- Commercial algorithms can achieve a similarity of over 96% between teeth and mouth shapes.
- It can provide an extremely fast response within 500 milliseconds, compared to the average response time of around 1.5 seconds.
- Support the integration of various intelligent agents.
- Supports 2D, 2.5D, and 3D.
- Supports super concurrency. The 3060, priced at over 1000 yuan RMB, supports 4 to 6 concurrent paths.
- Support cloud deployment, local deployment, and information technology innovation transformation.
- Support performances such as singing, dancing, and changing clothes.
- Supports RAG, workflow, and agent orchestration.
- Low latency and high synchronization, ensuring high synchronization between audio and video lip shape, action, and voice.
- Supports multiple languages and switching between multiple models.
- Highly robust automatic speech recognition (ASR) + text-to-speech (TTS).
