Researchers have developed a new method called Phoneme-Driven Gaussian Splatting (PD-GS) to improve the accuracy of lip articulation in audio-driven talking head generation. Traditional methods often result in over-smoothed mouth movements and fail to capture crucial articulatory events like lip closures. PD-GS addresses this by integrating time-aligned phoneme tokens, derived from an automatic speech recognition and forced-alignment pipeline, with continuous audio embeddings. This approach allows for smoother dynamics while ensuring precise guidance on phoneme sequences, leading to more linguistically faithful neural avatars. AI
