초록

The purpose of this study is to analyze the EGG measures from Lx Speech Studio program (Laryngograph Ltd, UK) in patient with vocal nodule. Thirty female adults (15 patient with vocal nodule, 15 normal speaker) produced sustained vowel and read the passage. They were grouped into three groups based on Grade (GRBAS) : normal-G0, nodule-Gl, nodule-G2. Estimates of Fx (Hz), Qx(%), Jitter, Shimmer, and HNR were made from a 500msec midportion of vowel. In addition, DFx(Hz), DQx(%), CFx(%) and CAx(%) were obtained from reading the passage. These data were compared among groups. The results were as follow Jitter, Shimmer, HNR were significantly higher in nodule-G2 group than in normal-G0 & patient-Gl group. In nodule-G2 group, CFx and CAx from reading passage were significantly higher. For patients with nodule, asymmetry or irregularity were observed in graphs of QxFx ＆ CFx provided by Quantitative Analysis.
