Abstract
The purpose of this study was to explore vocal responses to pitch perturbation on the flat, rising, and falling contour made of sequences of level tones in Taiwanese Southern Min. Twenty-two native speakers produced nine disyllabic words (flat: high-high, mid-mid, and low-low tone sequences; rising: mid-high, low-high, and low-mid tone sequences; falling: high-mid, high-low, and mid-low tone sequences). Pitch-shift stimuli (200 ms) appeared at either 100 ms (the beginning of the first syllable) or 400 ms (the beginning of the second syllable) after vocal onset. The participants were asked to ignore the pitch perturbation that appeared via auditory feedback. We found their compensation decreased when both syllables had identical level tones (i.e., the flat contour) but was particularly large when the overall contour was falling. Furthermore, pitch compensation at 100 ms was smaller than at 400 ms for the falling contour, but not for the flat and rising contours. Our results suggest that less susceptibility to pitch perturbation in the initial speech planning process is conditioned by the velocity of overall pitch contour.
