Abstract

Background and Objectives: Smoking has been identified as one of the main determinants of negative changes on the larynx histology. The purpose of this study is to investigate the voice characteristics and correlation between voice parameters of the smokers with vocal polyp or nodule or both of them. Materials and Method: MPT, $F_0$, jitter, shimmer, NHR of Korean /a/ vowel from 54 smokers and 50 nonsmokers diagnosed as vocal polyp or nodule were analyzed. A Computerized Speech Lab (4400) was for the analysis of each voice sample and statistical analysis was done by one-way ANOVA and Pearson correlation coefficient. Result and Conclusion: It showed that we can find difference between smokers and nonsmokers group in MPT, $F_0$, jitter, shimmer were different except NHR. each group shows difference in correlation coefficient between MPT, $F_0$, jitter, shimmer.
