What is it about?
High variability among raters remains a central issue for auditory-perceptual judgments, and auditory training is one way to improve rater reliability and rating validity. This is the first study to explore the effects of a stimulus-response-feedback training paradigm on rater reliability, criterion validity, and the magnitude of visual analog scaling of dysarthric features.

Why is it important?
The verdict is that auditory training can produce meaningful improvements in inter-rater reliability. The validity of non-expert ratings is high even without training, except for the feature, monotony. The magnitude of scaled scores remains unaltered with training, which is considered a positive effect since lowering of scores post-training when validity is high could be interpreted as exposure-related desensitization to disordered speech samples.
Perspectives
The current study drew from the extensive voice and auditory training literature and brought together scientists and clinicians working with motor speech disorders. There remains much to be done in this area, and it felt rewarding to pave the way for future work.
