Abstract
|
|
|
|
Aerodynamic analysis study was performed on 14 normal subjects (2 males, 12 females) with nonsense syllables composed of Korean bilabial stops (/p, /´, /^h) and their preceding and/or following vowels, /i, a, u/. That is, [pi, p´i, p^hi, pa, p´a, p^ha, pu, p´u, p^hu, ipi, apa, upu, ip^hi, ap^ha, up^hu, ip´i, ap´a, up´u]. All measures were taken and analysed using Aeriphone Ⅱ voice function analyzer and included peak air pressure, mean air pressure, maximum flow rate, volume, mean SPL and phonatory SPL. A t-test and one-way ANOVA were employed for analysis A post-hoc analysis was performed with Scheffe and Bonferroni. The results were as follows: First, MSPL and MAP of /p, ;´, ;^h/ were significantly different in different positions *initial and medial position). In addition, different vowel dnvironment also produced significantly different aerodynamic characteristics those consonants. Especially the lax consonant /p/ was significantly different /i, a, u/ vowel environments. The rense consonant /p´/ was significantly different only /i/ vowel environment.
