This paper reports on the correlation between word confusion matrices from Word-Error-Rate (WER) experiments and different phonetic distance measures. The investigated phonetic distance measures are based on the minimum-edit-distances between phonetic transcriptions and the distances between Hidden-Markov-Models (HMM). We show that phonetic distance(More)
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(More)
The Audio-Visual Face Cover Corpus consists of high-quality audio and video recordings of 10 native British English speakers wearing different types of ‘facewear’. Speakers read aloud a set of 64 /C1VC2/ syllables embedded in a carrier phrase. 18 English consonants occurred twice each in onset and coda positions. Speakers recited the list 1+8 times, i.e.(More)
The study presented in this paper investigates auditory-only and auditory-visual (AV) consonant recognition where the talker's face is obscured by various types of face-concealing garments and headgear. Observers' consonant identification performance across the various 'facewear' conditions was tested both in quiet listening conditions (Experiment 1), and(More)
Compounds with the capacity to induce antigen-specific unresponsiveness in CD4(+) T cells can in some clinical situations be more beneficial than general immune suppressants. Newly synthesized ester, ester/amide, and amide derivatives of butyrate with the capacity to induce antigen-specific T cell unresponsiveness in vivo and in vitro were tested here. The(More)
Sensitivity to noncontrastive subphonemic detail plays an important role in adult speech processing, but little is known about children's use of this information during online word recognition. In two eye-tracking experiments, we investigate 2-year-olds' sensitivity to a specific type of subphonemic detail: coarticulatory mismatch. In Experiment 1, toddlers(More)
