Real-Time Lip Sync for Live 2D Animation presents a distinctive deep learning system designed for live broadcasts and streaming platforms, which generates lip sync for 2D animations in real time. The system utilizes a Long Short Term Memory (LSTM) model and provides low-latency processing, vital for live interaction.

• Addresses the need for quick and reliable lip sync to enable 2D characters to interact with live audiences.
• Leverages a deep learning LSTM model to produce accurate lip sync with minimal delay.
• Introduces design methods that provide a predictive edge to improve synchronization accuracy.
• Implements data augmentation to enhance model performance with limited hand-animated training samples.
• Results are favored over other methods, including non-live, through extensive human judgment tests.

The technology showcased in this paper is imperative for the evolving landscape of virtual entertainment and interactive media. As it facilitates more realistic and immediate interactions between 2D characters and viewers, the potential applications for this system extend to educational content, virtual meetings, and interactive storytelling.
