Perception of continuous acoustic cues in speech revealed by the auditory N1 and P3 ERP components

Toscano, J. C., & McMurray, B. (2012, October). Poster presented at the 2012 Neurobiology of Language Conference, San Sebastian, Spain.

Abstract: Many models of speech perception posit that listeners perceive speech sounds categorically (i.e., that the units of speech perception are phoneme categories), and behavioral and electrophysiological evidence has supported this... Read more →

Measuring acoustic cue encoding and categorization during speech processing using the auditory N1 and P3 ERP components

Toscano, J. C., & McMurray, B. (2011, November). Paper presented at the 10th Auditory Perception, Cognition, and Action Meeting, Seattle WA.

Abstract: An important question in speech perception is whether listeners encode speech sounds in terms of continuous acoustic cues at early stages of processing or whether they perceive them only in terms of categories... Read more →

Continuous perception and graded categorization: Electrophysiological evidence for a linear relationship between the acoustic signal and perceptual encoding of speech

Toscano, J. C., McMurray, B., Dennhardt, J., & Luck, S. J. (2010). Psychological Science, 21, 1532-1540.

Abstract: Speech sounds are highly variable, yet listeners readily extract information from them and transform continuous acoustic signals into meaningful categories during language comprehension. A central question is whether perceptual encoding captures acoustic detail in a one-to-one fashion or whether it is affected by phonological categories... Read more →

Perception of voicing is graded all the way down

Evidence from electrophysiology

Toscano, J. C. & McMurray, B. (2008, October). Talk presented at the 14th Midcontinental Workshop on Phonology, University of Minnesota, Minneapolis, MN.

Abstract:

Phonological distinctions, such as voicing, are manifested as variations in continuous acoustic cues in the speech signal. These cues are ultimately categorized into a small number of distinct phonological categories... Read more →
