| Sumario: | A commentary on an article by N. Roy, B. Weinrich, S.D. Gray, K. Tanner, S.W. Toledo, H. Dove, et al. that appeared in the Journal of Speech, Language, and Hearing Research, vol. 45, pp. 625–638. In the article, Roy et al. examined whether public school teachers with complaints of voice difficulties perceived improvements in their voice abilities following either a program of vocal hygiene suggestions or use of a portable voice amplification (VA) device and concluded that the results of their investigation clearly support the clinical utility of VA treatment for dysphonic school teachers. The writers question this interpretation and outline five principal points of contention that call into question both the validity and reliability of the results. A response from Roy et al. is provided.
