ESCA Workshop on Automatic Speaker Recognition, Identification, and Verification
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.
