Voice quality in Australian English.

This study is an acoustic investigation of voice quality in Australian English. The speech of 33 Indigenous Australians (Aboriginal English speakers) is compared to that of 28 Anglo Australians [Mainstream Australian English (MAE) speakers] from two rural locations in Victoria. Analysis of F0 and H1*-H2* reveals that pitch and voice quality differ significantly for male speakers according to dialect and for female speakers according to location.

Duration and Voice Quality of Early Infant Vocalizations.

Purpose: Infant vocal durations have been studied from a variety of perspectives, including medical, social, and linguistic. The resultant developmental profile across the first 6 months of life, however, is still far from clear. The purpose of this study was to evaluate the durational properties of infant vocalizations from the unique perspective of voice quality.
