Introduction Lozenges are often taken as off the counter or based on the physician's instructions. It is usually taken to facilitate a soothing effect on the vocal tract due to irritation or discomfort caused at the level of the oropharynx during upper respiratory tract infections. Aim The purpose of this study was to investigate the effects of lozenges on vocal tract by assessing the voice related acoustic parameters. Material and Method A total of 60 patients were included in the study. The Acoustic parameters were obtained using Dr. Speech before consuming a lozenge and 30 minutes after consumption of a lozenge. The parameters assessed were Frequency (F0), Jitter, Shimmer, and Harmonics to Noise Ration (HNR). Results Significant differences were seen in HNR of the affected population.
