“Stability in perceptual assimilation: Talker and vowel context
effects.” Presented at the 148th Meeting of the Acoustical Society of The perceptual assimilation of non-native sounds (i.e.,
the manner in which non-native sounds are identified with native perceptual
categories and their internal structure) may predict the ease with which
these sounds can be discriminated and ultimately acquired in second language
acquisition ( Specifically,
the role of Talker Variability (single talker vs. multiple talker within
trials) and the Context in which identification judgments are elicited (same
context as the discrimination test; isolation) is being investigated for
target non-native sounds in isolated words and in words in a short frame
sentence. The relationship between cross-language consonant perceptual
assimilation and discrimination using stimuli produced and presented under
different phonetic and prosodic contexts is being examined in the remaining
two experiments using the optimal identification-discrimination test pair.
The results and interpretation of the proposed study will a) provide a more
precise understanding of how different phonetic and prosodic contexts affect
cross-language consonant perceptual assimilation, b) clarify important
methodological issues that obscure our interpretation of perceptual
assimilation experiments, and c) provide a theoretical and empirical
background for formal modeling of cross-language speech perception and
