Rethinking Voice-Face Correlation: A Geometry View
This provides a new perspective on voice-face correlation for anthropometry science, but is incremental as it builds on prior work by shifting to a geometry view.
The paper tackles the problem of reconstructing 3D facial shape from voice by focusing on geometry rather than semantic cues, finding significant correlations between voice and specific facial parts like the nasal cavity and cranium.
Previous works on voice-face matching and voice-guided face synthesis demonstrate strong correlations between voice and face, but mainly rely on coarse semantic cues such as gender, age, and emotion. In this paper, we aim to investigate the capability of reconstructing the 3D facial shape from voice from a geometry perspective without any semantic information. We propose a voice-anthropometric measurement (AM)-face paradigm, which identifies predictable facial AMs from the voice and uses them to guide 3D face reconstruction. By leveraging AMs as a proxy to link the voice and face geometry, we can eliminate the influence of unpredictable AMs and make the face geometry tractable. Our approach is evaluated on our proposed dataset with ground-truth 3D face scans and corresponding voice recordings, and we find significant correlations between voice and specific parts of the face geometry, such as the nasal cavity and cranium. Our work offers a new perspective on voice-face correlation and can serve as a good empirical study for anthropometry science.
