Smoking affects the voice quality and the previous studies presented higher Voice Handicap Index (VHI) scores, and abnormal acoustic data in smokers. However, there is no study revealing any voice parameter indicating incipient damage in voice functionality. The studies documented that the adverse effects of smoking on phonatory function were higher in females than males and further the prevalence of smoking among females tends to increase. The purpose of this study was to investigate the effect of smoking on the acoustic and auditory-perceptual analysis of the speaking voice in female smokers who scored the VHI-10 scale as grade 0 (absent), and thus to look for a criterion for incipient vocal damage of smoking.

The study group composed of 22 female smokers and 22 female nonsmokers between the ages of 18 and 55 years. The acoustic parameters (mean F0, jitter local [%], jitter local …
