The Effect of Cigarette Smoking on Vocal Parameters

LKA-NRW, Düsseldorf, Germany

This contribution addresses the effect of smoking from an acoustic phonetic point of view. 40 speakers served as subjects (20 smokers and 20 non-smokers). The parameters investigated are mean F0, jitter, shimmer, and HNR. Generally, a large overlap was observed between the two groups. No statistically significant differences were observed between group means for average F0 and jitter; shimmer and HNR were found to be marginally significant for all smokers and highly significant for a subgroup of long-term smokers as compared to the controls. A subgroup of heavy smokers on the other hand, was best distinguished from the non-smokers by F0 results.
