Speaking under Cover: The Effect of Face-concealing Garments on Spectral Properties of Fricatives.
Natalie Fecher, Dominic J. L. Watt · ICPhS · 2011
This paper firstly reports on the design of an audiovisual ‘face cover’ corpus. High-quality audio and video recordings were taken of 10 speakers reading phonetically-controlled stimuli under various face disguise conditions. Possible articulatory, acoustic and perceptual effects of the masks in a forensic context are introduced. Secondly, preliminary results of a spectral analysis of voiceless fricatives, taken from a subset of speakers, are presented.
