LiteAvatar's Real-Time Audio Driver Technology
LiteAvatar is an innovative open-source tool developed by Ali's HumanAIGC team that focuses on generating facial animations of 2D avatars in real-time through audio input. The core of the tool's technology is the perfect combination of speech recognition (ASR) and mouth prediction technology, which can accurately capture audio features and translate them into natural and smooth facial expressions and mouth movements. As a CPU-friendly solution, it breaks through the traditional limitation of needing GPU support and realizes high frame rate animation output of 30fps by CPU alone, which makes it especially suitable for real-time applications in low-power environments.
- For audio analysis: it uses advanced ASR model to extract speech feature parameters
- For animation generation: accurate mouth synchronization prediction by lightweight neural network models
- Performance optimization: specially designed algorithms ensure high performance on resource-constrained devices
