Audio-Visual Speech Representation Expert for Enhanced Talking Face Video Generation and Evaluation
arxiv(2024)
摘要
In the task of talking face generation, the objective is to generate a face
video with lips synchronized to the corresponding audio while preserving visual
details and identity information. Current methods face the challenge of
learning accurate lip synchronization while avoiding detrimental effects on
visual quality, as well as robustly evaluating such synchronization. To tackle
these problems, we propose utilizing an audio-visual speech representation
expert (AV-HuBERT) for calculating lip synchronization loss during training.
Moreover, leveraging AV-HuBERT's features, we introduce three novel lip
synchronization evaluation metrics, aiming to provide a comprehensive
assessment of lip synchronization performance. Experimental results, along with
a detailed ablation study, demonstrate the effectiveness of our approach and
the utility of the proposed evaluation metrics.
