AD-NeRF: Audio Driven Neural Radiance Fields for Talking Head Synthesis

AD-NeRF generates photorealistic talking-head video directly from audio using neural radiance fields, bypassing the 2D landmarks or 3D face model intermediaries used by prior methods. By conditioning an implicit neural function on audio features and rendering via volume rendering, it achieves both head and upper body generation with free-viewpoint control.
