Voice is the primary means of communication and also plays a significant role in individuals’ daily life. It expresses their personal information like social status, personal qualities, and the emotional state. A wide range of factors such as quality, strength, accuracy, flexibility of sound affects the physiology of healthy voice production (Boone, 2013) . People can either smoke, chew or sniff tobacco. Smoking is the inhalation of smoke by burning tobacco which is wrapped in cigarettes, pipes and beedis. It causes irritation of the larynx which has a chance for developing damage and ailment in future. The foremost aim of the study is to analyze the acoustic voice characteristics using PRAAT software version 6.0.32, aerodynamic measures using Maximum Phonation Duration (MPD), perceptual voice characteristics using Grade, Roughness, Breathiness, Asthenia and Strain (GRBAS) rating scale and self-perception of voice using Voice Handicap Index 10 (VHI-10) among filtered and un-filtered cigarette smokers. Thirty men aged 25 to 50 years were recruited for the study. They were grouped as Group A: 15 filtered cigarette smokers and Group B: 15 un-filtered cigarette smokers based on their smoking products. The test outcomes were analyzed using descriptive analysis and Paired sample‘t’ test in SPSS version 25. A significant difference in acoustical voice characteristics was noted among both the groups. The results highlighted that the smoking product had a significant impact on the voice characteristics. Therefore, it should be considered as an important factor during the assessment and management of voice.
