Abstract:
Examined are factors affecting vibration type in voiced sounds. Several properties of glottal flow waveforms that could be distinctive for phonation types such as "breathy" voice are examined in the study of Hmong, which shows a contrast between 5 tones produced with normal voice & 2 produced with breathy voice. Three M Hmong speakers produced tokens of real or nonsense words in 3 normal voice & 1 breathy voice tone. Combined oral & nasal airflow were recorded & analyzed. Spectral differences in glottal flow were sought. It was found that breathy & normal vowels show a contrast in spectral shape & pulse shape of the glottal waveform. Flow pulse symmetry & spectral tilt were not found to be significant distinguishing factors. Implications of the findings for cross-linguistic phonetic investigations are discussed. Figures. B.
