Auditory-perceptual evaluation of rough and breathy voices: correspondence between analogical visual and numerical scale.

Purpose: To determine the cut-off values of different degrees of vocal roughness and breathiness in an analogical visual scale, from a numerical scale.

Methods: We selected 150 voices from both genders, with quality ranging from neutrality to intense deviations, and predominance of breathiness or roughness. The auditory-perceptual assessment through two scales: 100-mm analogical visual scales and 4-point numerical scale.

Comparative analysis of vocal fold vibration using high-speed videoendoscopy and digital kymography.

Objectives: To compare high-speed videoendoscopy (HSV) and digital kymography (DKG) in the vocal fold vibration analysis of normophonic women with no vocal fold abnormalities.

Study Design: Prospective study comparing quantitative parameters extracted by HSV and DKG.

Methods: Eighteen normophonic women whose age ranged from 18 to 45 years participated in the study.
