Accurate Audio Analysis and Mouth Prediction Technology
The key to LiteAvatar's outstanding mouth synchronization is its deep integration of the ModelScope platform's advanced ASR technology. Technical highlights of the system include:
- Using hybrid neural network architecture to handle speech recognition and visual feature extraction simultaneously
- Constructed a complete articulatory visual library containing dozens of basic articulation patterns
- Realization of non-linear mapping of phonemes to mouthparts to handle complex co-articulation phenomena
- Incorporates a speed-adaptive mechanism to ensure natural performance at fast and slow speeds.
Actual tests show that the system's recognition accuracy for Chinese Mandarin exceeds 95%, and the English support also reaches a professional level. Together with the specially developed timing smoothing algorithm, the generated animation completely avoids the mouth jitter and delay problems commonly found in traditional solutions.
