Fricative Vowels in Changzhou Wu: An Acoustic and Articulatory Study
… vowels based on formants, spectrograms, zero-crossing rate (ZCR), and harmonics-to-noise ratio (HNR). The results reveal that the two types of fricative vowels exhibit different frication patterns and that tone influences not only the frication noise of coronal fricative vowels but also …
