The ratings were made using a multidimensional protocol with four-point equal-appearing interval scales. The stimuli consisted of text reading by authenticdysphonic patients. The consensus training for each perceptual voice parameter included (1) definition, (2) underlying physiology, (3) presentation of carefully selected sound examples representing the parameter in three different gradesfollowed by group discussions of perceived characteristics, and (4) practical exercises including imitation to make use of the listeners’ proprioception.Results: Intrarater reliability and agreement showed a marked improvement for intermittent aphonia but not for vocal fry.
