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.

Abstract:

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 →

Cue Integration With Categories: Weighting Acoustic Cues in Speech Using Unsupervised Learning and Distributional Statistics

Toscano, J. C., & McMurray, B. (2010). Cognitive Science, 34, 434-464.

Abstract: During speech perception, listeners make judgments about the phonological category of sounds by taking advantage of multiple acoustic cues for each phonological contrast. Perceptual experiments have shown that listeners weight these cues differently. How do listeners weight and combine acoustic cues to arrive at an overall estimate of the category for a speech sound?.. Read more →

Using the distributional statistics of speech sounds for weighting and integrating acoustic cues

Toscano, J. C. & McMurray, B. (2008). In B. C. Love, K. McRae, & V. M. Sloutsky (Eds.), Proceedings of the 30th Annual Conference of the Cognitive Science Society (pp. 433-438). Austin, TX: Cognitive Science Society.

Abstract: A great deal of behavioral evidence suggests that infants can use distributional statistics to learn speech sound categories. .. Read more →

Integrating acoustic cues to phonetic features

A computational approach to cue weighting

Toscano, J. C. and McMurray, B. (2007, October). Poster presented at Where Do Features Come From? Phonological Primitives in the Brain, the Mouth, and the Ear. Paris, France.

Abstract:

A central issue in phonology and speech perception is the relationship between acoustic cues in the speech signal and the features they correspond to... Read more →
