Audio-Driven Emotion-Aware 3D Talking Face Generation from Single Image

Audio-driven talking face generation from a single source image is a popular research topic. There still exist many challenges for its practical applications, e.g., diverse motion generation, effective emotional control, and large view angle changes. In this work, we propose a novel one-shot emotion-controllable audio-driven 3D talking face generation framework, which creates free-view talking videos from one reference image. Firstly, to synchronize the motion with the input audio, we use a transformer-based motion generator to capture the context of the input audio and predict motion coefficient sequences, which are leveraged by a motion encoder to extract motion codes. Meanwhile, to reconstruct a 3D portrait from one reference image, an identity encoder is utilized to extract an identity code and generate emotion-dependent appearance with a specific emotion label. Finally, we introduce an emotion-controllable 3D portrait video generator to synthesize free-view talking videos using the disentangled motion and identity codes. Thanks to the audio-synchronized motion codes and emotion-aware identity code, we can render a talking face with realistic emotional expressions in novel views. Extensive experiments show that our method is capable of maintaining superior visual performance and motion accuracy in both front view and novel views.
