Measuring perceptual encoding and categorization of speech sounds using an ERP approach

Toscano, J. C., & McMurray, B. (2012, January). Poster presented at the 6th Conference of the Auditory Cognitive Neuroscience Society, Tucson, AZ.

Abstract:

To recognize speech, listeners must map continuous acoustic features in the sound signal onto discrete units (e.g., phonemes, words). An important question is whether speech sounds are initially encoded in terms of continuous cues or whether listeners perceive them only in terms of categories... 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 →

Perceiving speech in context

Compensation for contextual variability at the level of acoustic cue encoding and categorization

Toscano, J. C. (2011). Doctoral dissertation, University of Iowa.

Abstract:

Several fundamental questions about speech perception concern how listeners understand spoken language despite considerable variability in speech sounds across different contexts (the problem of lack of invariance in speech)... 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 →
