Consonant effects on tonal registers in Jiashan Wu

Abstract

Breathy phonation is known as the primary cue of the “voiced” stops in Wu dialects, and is associated with the lower tonal register. This study discusses the phonetic realization of the tonal register of Wu dialects by measuring relative prominence of the first harmonic to some higher-frequency components in the spectrum, F0 and periodicity (CPP) of Jiashan Wu monosyllabic words. We find that in Jiashan Wu, the phonetic targets for tonal register contrasts are a steeper spectral-slope and a lower F0, which is consistent cross all consonant manners, while the articulatory realization varies among different types of consonants.
