Pollo AI's lip synchronization engine uses a bi-directional LSTM neural network to achieve accurate lip-synchronization at the 5ms level by analyzing the mapping relationship between audio spectral features and the 52 muscle movement points on the face. Tests show that for English content synchronization accuracy reaches 98%, Chinese and other tone languages synchronization accuracy 92%, far exceeding the industry level of 70% for traditional keyframe animation. Users only need to upload video and audio files, and the system can complete the generation of minute-level video lip movements in 23 seconds, supporting the intelligent switching of multilingual mixed content. The technology has been applied in the field of online education to help teachers quickly create multi-language teaching videos; in game NPC animation production, it can increase the efficiency of dubbing by 10 times.
