This study determine the influence of smoking habits to the voice handicap score by Voice Handicap Index score (VHI). The design was a retrospective cohort study from 96 adults that identified level of voice fatigue through VHI. From the history there were divided into 3 groups: a group of active smokers, passive smokers and nonsmokers. The statistical test used was Chi-square test and regression nominal test. Voice fatigue (VHI score > 20) in both active smokers (13.54%) and passive smokers (15.62%) compared with nonsmokers (6.25%), by Chi-square test results was p = 0047 (p <0.05). Nominal regression test between 3 groups of samples were (RR = 3.0, CI 95% = 0.95 to 9.21) between the group of active smokers and passive smokers (RR = 3.8, CI 95% = 1,23-11.80 ). Smoking habits influence the voice handicap score in both active smokers and passive smokers compared with nonsmokers. Active smokers have a risk of fatigue voice 3 times more often than nonsmokers and passive smokers have a risk 3.8 times more often than non-smokers.
