Speech-driven Facial Animations Improve Speech-in-Noise Comprehension of Humans
[article]
2021
bioRxiv
pre-print
Here we consider facial animations produced by a recently introduced generative adversarial network (GAN), and show that humans cannot distinguish between the synthesized and the natural videos. ...
Importantly, we then show that the end-to-end synthesized videos significantly aid humans in understanding speech in noise, although the natural facial motions yield a yet higher audiovisual benefit. ...
We note, however, that the standardized nature of the sentences in the GRID corpus might have hindered the differentiation between the natural and synthetic videos. ...
