Summary Oral-motor exercises implemented by speech-language pathologists as a treatment method to improve speech production have caused heated debate in the communication disorders field. These treatment programs claim to increase muscle tone/strength and oral postures necessary for speech production through nonspeech motor exercises. One specific oral-motor treatment program implemented by Rosenfeld-Johnson in 1995 is the “Horn Blowing Hierarchy.” This program involves the use of 12 horns that are structured in ascending order according to increasing aerodynamic resistance. Although widely adopted by practicing speech-language pathologists, there is little empirical evidence behind the effectiveness and efficacy of the treatment. The purpose of the study was to examine the aerodynamic resistance required to generate sound from each horn. The data revealed differences in resistance between the horns, but no systematic increase in aerodynamic resistance along the horn hierarchy. The significance of this study lies in the impact of the results on evidence-based treatment: the resistances of the horns do not incrementally increase, suggesting that the treatment program may not be a valid approach to exercising the oral musculature.
