Assessing the assessment

Toscano, J.C., Trevino, A., & Allen, J.B. (2013, October). Assessing the assessment: Measuring listeners’ speech recognition errors for specific consonants and tokens. Poster presented at the 2013 Aging and Speech Communication Conference, Indiana University, Bloomington, IN.

Abstract: A critical issue for understanding speech perception, as well as assessing the effects of age-related hearing loss, is identifying the factors that cause listeners to make speech recognition errors... Read more →

Computing the reliability of acoustic information in speech

Invited talk presented at the Dept. of Linguistics, Northwestern University, May 2013.

Abstract: Many researchers have observed that speech sounds vary considerably across different contexts, an issue known as the lack of invariance. Given this variability, how much information is conveyed by individual acoustic cues? That is, how reliably do specific cues distinguish phonological contrasts?.. Read more →

Acquiring and adapting phonetic categories in a computational model of speech perception

Toscano, J. C. (2013, April). Invited paper presented at the Workshop on Current Issues and Methods in Speaker Adaptation, Ohio State University, Columbus, OH.


Recent work on perceptual adaptation has demonstrated that listeners can learn novel distributions of acoustic cues in unsupervised learning tasks with only a small amount of experience (Clayards, Tanenhaus, Aslin, & Jacobs, 2008, Cognition; Munson, 2011, dissertation)... Read more →

A common mechanism for the acquisition of phonetic categories during development and perceptual learning in adulthood

Toscano, J. C. (2013, February). Invited paper presented at the Department of Linguistics, University of Illinois at Urbana-Champaign.

Abstract: During language acquisition, one of the first tasks encountered by infants is determining which sounds indicate phonological distinctions in their language and which do not. This is a particularly challenging problem, since it requires unsupervised learning (i.e.,.. Read more →

Task effects on prosodic prominence

Buxó-Lugo, A., Toscano, J. C., & Watson, D. G. (2013, March). Paper presented at the 26th Annual CUNY Conference on Human Sentence Processing.


Most prosody research is conducted on spoken corpora or on speech samples collected from laboratory studies. However, laboratory studies often use referential communication tasks in which speakers talk to a computer and the communicative “stakes” are low... Read more →

Examining talker context effects in speech perception

Toscano, J. C., & McMurray, B. (2012, November). Paper presented at the 11th Auditory Perception, Cognition, and Action Meeting, Minneapolis, MN.

Abstract:  A number of researchers have become interested in the effects of indexical information on speech perception. A commonly studied indexical cue is talker gender, which produces systematic changes in acoustic cues that are relevant for speech... Read more →
