Analysis of the Transitional Acoustic Features of Unaspirated Plosivess in Wuming Mandarin Based on Linear Regression Model
Hongli Deng, Gaochao Huang, Na Chen, Xianying Wang · 2023
This paper utilizes a linear regression model to construct acoustic locus equations for the F2 onset values and target values of unaspirated plosive consonants in Wuming Mandarin. The analysis focuses on the role of acoustic trajectories and coarticulation in speech production. The results indicate that the calculated acoustic trajectories based on the locus equations can effectively distinguish between bilabial and alveolar plosives consonants, while the locus of velar plosives consonants varies depending on the following vowel. The coarticulation effect is minimal for alveolar plosives, maximal for velar plosives, and intermediate for bilabial plosives.
