Abstract:
An observational study of acoustic voice parameters was made in non-dysphonic adult smokers and non-smokers. The sustained vocal /a/ of 79 smokers and 169 non-smokers was recorded with Mini-Disk equipment. Acoustic analysis was performed with the Dr. Speech Science 3.0 program. Some acoustic parameters differed between smokers and non-smokers: the fundamental frequency (FQ) was lower in smokers. Average jitter (PPQ) and shimmer (APQ) were higher in smokers (Ji:0.27%, Shi: 2.56%) than in non-smokers (Ji: 0.23%, Shi: 2.02%). HNR and NNE values did not differ significantly.
