EFFECT OF ACOUSTICAL, VISUAL AND TACTILE REVERBERATION ON SPEECH FLUENCY OF STUTTERERS

The study presents the comparison of the effects of reverberation tran smitted 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 tr ansmission channels the stuttering intensities and the speech velociti es decreased with the increase in reverberation time. The results were analyzed statistically by means of the ANOVA method. It was proven th at the corrective effects of visual reverberation and tactile reverber ation were comparable. Reverberation transmitted via the auditory chan nel was more effective than when transmitted via the visual or tactile channels. Connecting the visual and tactile channels with the auditor y channel has no influence on the effectiveness of reverberation.
