Examining Pitch-Accent Variability from an Exemplar-Theoretic Perspective

This paper presents an exemplar-theoretic account of pitch-accent variability. Results from two experiments are reported. The first experiment examines variability / similarity across a range of pitch-accent contour types which vary in frequency of occurrence. The results report similar behaviour across the frequency bins and are indicative of pitch-accent immunity from frequency effects. The second experiment, in order to establish the impact of lexical frequency on pitch-accent production, examines the similarity of pitch-accent contours linked to high and low frequency syllables. The results indicate further autonomy on the part of pitch-accents and offer possible evidence for post-lexical pitch-accent generation.
