Summary: Hsiang-yu
This study examined the
acoustic patterns of syllables with/without a nasal coda in Standard Chinese (SC)
by applying syllable boundary detection based on calculation of nasal
correlates, namely A1−P0 and A1−P1 (amplitude difference between the first
formant and nasal peaks). Adopting tokens from 5 male and 5 female Standard
Chinese speakers, this study showed that a nasal-ended syllable followed by a
stop or vowel initial is distinguishable from an open syllable followed by a
stop or nasal initial when the previous vowel is a monophthong [a], [i], or [ǝ].
The presence of nasal codas in SC can be detected based on the vowel-nasal
consonant boundary if oral closure is formed for the nasal consonant. In some
cases of VN-V without nasal murmur due to the lack of closure, the maximum,
minimum and slope of A1-P0 and A1-P1 can be used to differentiate them from
sequences without nasals. The above variables are also acoustic cues for the nasal
place of articulation.
