Exemplar encoding of intonation in syllables, words and phrases
What is the phonological interval that defines the domain of cognitive encoding of intonational phonetic detail? This study investigates the question for American English by modeling f0 contour similarity between imitated sentences and their stimuli over domains of varying size and prosodic status, from the syllable to the prosodic phrase. Results show the greatest similarity between imitated and stimulus f0 contours in the prosodic phrase (ip) domain analysis. These findings contribute to previous studies showing speakers’ adaptation of intonational phonetic detail, and call for an extension of exemplar models to include phonetically detailed representations of f0 patterns in prosodic phrases.
