한국어 마찰음, 파찰음, 치조 파열음의 음향학적 및 공기역학적 특성에 관한 여구

Abstract

Background and Objectives : 10 normal Korean native speakers participated subjects to investigate the acoustic and aerodynamic study of Korean fricatives, affricates, and plosives and to make good use of the results for the patients with articulation problems.

Materials and Method : Their productions of [asa], [as’’a], [aca], $[ac^ha]$, (ac’’a), (ata) , $[at^ha]$, and [at’’a] were analyzed with Lx Speech Studio Program (Laryngogrtaph Ltd, UK) for acoustic analysis and Phonatory Function Analyze. (Nagashima Ltd. Model PS 77H, Tokyo, Japan) for aerodynamic analysis.

Results : The results are as follows : 1) Plosives showed higher Qx1 in vocal folds closure ratio than fricatives and affricates. 2) Tense fricatives, affricates, and plosives showed higher Qx2 in vocal folds closure ratio than asperated and 1ax. 3) Asperated showed higher Qx1 in vocal folds closure ratio than tense and 1ax. 4) Asperated showed higer peak flow rate than tense and 1ax.

Conclusion : This results may be helpful for treatment in articulation disorders.
