Abstract:
Speech communication commonly occurs in the presence of noise. Research on the perception of speech in noise has largely focused on the perceptual availability of target phonetic information in the presence of various noise maskers (e.g., white noise, speech-shaped noise, temporally modulated noise, and multi-talker babble). Previous work has shown that a glimpsing model and a modified Articular Index model closely approximate overall accuracy of noise-masked speech perception (Cooke, 2006, JASA; Allen, 2005; JASA). Some recent work has focused on variation in confusion patterns across listeners (Silbert, 2012, JASA, 2014, Lab. Phon.) and on difference in perceptual error rates across and within consonant categories (Toscano & Allen, forthcoming, JSLHR). The present work focuses on listener and stimulus-talker variation in the identification of consonants. Eleven listeners identified numerous tokens of each of four consonants (t, d, s, z) in CV syllables produced by 20 talkers (10 male, 10 female) masked by 10-talker babble. Data plots and multilevel logistic regression model fits indicate substantial variation in talker-specific influences on identification accuracy as well as substantial interactions between talker and stimulus category. Analysis of perceptual confusion patterns via a multilevel, multidimensional Gaussian signal detection model will also be presented.
