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)
The Scottish Vowel Length Rule (SVLR) – formerly ‘Aitken’s Law’ [1, 5, 6] – is a contextconditioned vowel length alternation that in Scottish and Northern Irish varieties of English coexists with the so-called Voicing Effect (VE, or ‘pre-fortis clipping’) [3]. It is known that SVLRlike alternations occur in varieties of English spoken in northern England(More)
Our social evaluation of other people is influenced by their faces and their voices. However, rather little is known about how these channels combine in forming "first impressions." Over 5 experiments, we investigate the relative contributions of facial and vocal information for social judgments: dominance and trustworthiness. The experiments manipulate(More)
We evaluate a vowel formant normalisation technique that allows direct visual and statistical comparison of vowel triangles for multiple speakers of different sexes, by calculating for each speaker a 'centre of gravity' S in the F 1 ~ F 2 plane. S is calculated on the basis of formant frequency measurements taken for the so-called 'point' vowel [i], the(More)
This paper presents part of an ongoing research program which aims to apply mathematical and geometrical analytic methods to vowel formant data to enable the quantification of parameters of variation of interest to sociophoneticians. We open with an overview of recent research working towards a set of desiderata for choice of normalization algorithm(s)(More)
