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 →

Measuring cue encoding and categorization

A classic question in speech perception concerns whether listeners are sensitive to the continuous acoustic features in the speech signal independently of phonological information. Recent work has shown that listeners can perceive within-category acoustic differences at the level of lexical representations. However, these responses also show effects of phonological categories. Thus, it is unclear whether there is an earlier stage of processing that is not influenced by category information...
