An acoustic voice analysis (fundamental frequency (F0), jitter, shimmer, noise to harmonic ratio (NHR), harmonic to noise ratio (HNR)) and an aerodynamic analysis (maximal phonation time (MPT)) were performed by an experienced otolaryngologist specialized in voice disorders for evaluation of objective voice quality and function. These analyses were performed on all the volunteers from both groups, and the results obtained were compared between the groups.
