Abstract: The study presents the comparison of the effects of reverberation transmitted via single and combined channels (auditory, visual and tactile) on the speech of stutterers. The dependence of stuttering intensity and speech velocity upon reverberation time was determined. For all transmission channels the stuttering intensities and the speech velocities decreased with the increase in reverberation time. The results were analyzed statistically by means of the ANOVA method. It was proven that the corrective effects of visual reverberation and tactile reverberation were comparable. Reverberation transmitted via the auditory channel was more effective than when transmitted via the visual or tactile channels. Connecting the visual and tactile channels with the auditory channel has no influence on the effectiveness of reverberation.
