Learning to Hear a Language: Perceptual Reorganization for Speech Sounds in Infancy
Wednesdays@NICO Seminar, Noon, November 29 2006, Chambers Hall, Lower Level
Prof. Jessica Maye, Northwestern University
Different languages utilize different sets of speech sounds and speech sound contrasts; for example, English distinguishes the sounds /l/ and /r/, as in the words 'rice' vs. 'lice', but Japanese does not. In this talk I will discuss how properties of the native language sound system affect listeners' perception of speech, such that speakers of different languages actually hear speech differently (an effect that may be thought of as foreign accented perception). Native language effects on perception begin during an infant's first year of life, before the acquisition of meaningful words. I will present evidence that infants' perception of speech sounds is shaped by statistical regularities in the speech that they hear during the first few months of life.
