Modeling age of exposure in L2 learning of vowel categories

Clayards, M. & Toscano, J. C. (2010, August). Poster presented at the 32nd Annual Conference of the Cognitive Science Society. Portland, OR.

Abstract: Age of exposure is known to be an important indicator of second language proficiency. Native-like phonological proficiency is attained only by learners exposed at the earliest ages. This paper examines one account of age-of-exposure effects... Read more →

Statistical learning of phonetic categories: Insights from a computational approach

McMurray, B., Aslin, R. N., & Toscano, J. C. (2009). Developmental Science, 12, 369-378.

Abstract: Recent evidence (Maye, Werker & Gerken, 2002) suggests that statistical learning may be an important mechanism for the acquisition of phonetic categories in the infant’s native language. We examined the sufficiency of this hypothesis and its implications for development by implementing a statistical learning mechanism in a computational model based on a mixture of Gaussians (MOG) architecture...

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 →
