The Chong language uses a combination of different acoustic correlates to distinguish among its four contrastive registers (phonation types). Electroglottographic (EGG) and acoustic data were examined from original fieldwork on the Takhian Thong dialect. EGG data shows high open quotient (OQ) values for the breathy register, low OQ values for the tense register, intermediate OQ values for the modal register, and rapidly changing high to low OQ values for the breathy-tense register. Acoustic correlates indicate that H1-A3 best distinguishes between breathy and non-breathy phonation, but measures like H1-H2 and pitch are necessary to discriminate between tense and non-tense phonation. A comparison of spectral tilt and OQ measures shows the greatest correlation between OQ and H1-H2, suggesting that changes in the relative amplitude of frequencies in the upper spectrum are not directly related to changes in the open period of the glottal cycle. OQ is best correlated with changes in the degree of glottal tension.
