Interaction between Articulatory Movements and Vocal Pitch Control in Japanese Word Accent

Abstract
In order to investigate the interaction between articulatory and vocal pitch controls, EMGs of the cricothyroid (CT) and sternohyoid (SH) muscles were recorded during utterances of two-mora Japanese words with rising and falling accent types in the Tokyo dialects. The test words consisted of combinations of open and closed vowels. It was revealed that the changes in CT activity were consistently observed in correspondence with the F₀ shift according to the accent types, while the SH muscle was observed to be active both for jaw opening and F₀ lowering, with some subject-to-subject difference. It was also observed that the time lag between the decrease in CT activity and the F₀ fall varied with a shift in the relative timing of SH activity in one subject, but not in the other. Articulatory jaw opening with SH activation was considered to positively contribute to F₀ lowering, but the use of this mechanism appeared to be optional at least in the Tokyo accent.
