Results: Eight articles have included the proposed criteria in the last 15 years. It was found seven cross-sectional studies and a literature review, which were categorized by the authors as follow: dysphonia and language comprehension, dysphonia and language comprehension in noisy environments; perception of dysphonic voice, vocal quality and speech rate.
