15th International Congress of Phonetic Sciences (ICPhS-15)
Understanding prosodic voice quality variations in English requires
both taking into account the various linguistic sources for changes
in voice quality and adequately tracking and measuring the range of
naturally occurring voice qualities in English. In this study, voice
quality variations were tracked using both quantitative measurements
and qualitative assessments. Samples were taken from 3 speakers producing
variants of a single sentence. Results show there are consistent effects
of prominence and phrase boundaries on voice quality. Both prominent
words and phrase-initial words display a "tenser" voice quality than
their non-prominent and phrase-final counterparts. Phonetic pitch
and phonological tone do not have an effect on modal voice quality.
There is, however, an increase in non-modal phonation associated with Low boundary tones, but not with low phonetic pitch.
