Combining cues to recognize speech

Acoustic measurements of phonetic cues to word-medial voicing

Toscano, J. C., & McMurray, B. (2012, November). Poster presented at the 53rd Annual Meeting of the Psychonomic Society, Minneapolis, MN.

Abstract: A great deal of work in speech has argued that invariant acoustic cues do not exist, leading many researchers to conclude that listeners use specialized representations, such as talkers’ inferred gestures, instead... Read more →

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 →

The consequences of lexical sensitivity to fine grained detail

Solving the problems of integrating cues and processing speech in time

McMurray, B., & Toscano, J. C. (2012, October). Paper presented at the 164th Meeting of the Acoustical Society of America, Kansas City, MO.

AbstractWork on language comprehension is classically divided into two fields. Speech perception asks how listeners cope with variability from factors like talker and coarticulation to compute some phoneme-like unit; and word recognition assumed these units to ask how listeners cope with time and match the input to the lexicon...

Voicing in English revisited

Measurement of acoustic features signaling word-medial voicing in trochees

Toscano, J. C., & McMurray, B. (2012, October). Poster presented at the 164th Meeting of the Acoustical Society of America, Kansas City, MO.

Abstract: A great deal of work in speech has argued that invariant acoustic cues do not exist, leading many researchers to conclude that listeners use specialized representations, such as talkers’ inferred gestures, instead... Read more →

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 →

The role of time in spoken word recognition

Evidence against temporal order in lexical representations

Toscano, J. C., Anderson, N. D., & McMurray, B. (2011, November). Poster presented at the 52nd Annual Meeting of the Psychonomic Society, Seattle, WA.

Abstract:  A challenging problem in spoken word recognition is time: speech unfolds over time, and  temporal order appears crucial for distinguishing words (cat vs... Read more →
