This study aimed to verify the effectiveness of voice rehabilitation exercises in rehabilitating voice quality in two cases suffering from hoarseness resulting from complications of infection with the Corona virus. In collecting the data, we relied on a GRBAS scale, the PRAAT software to identify the maximum phonation time (MPT), and finally, the voice handicap index. The study concluded that vocal rehabilitation has a positive effect on improving sound quality based on the indicators adopted by the study in the evaluation.
