Decreases in Stuttering Frequency as a Function of Continuous and Contingent Forms of Auditory Masking This experiment examined the effects of continuous and contingent white noise masking upon the speech of 10 stutterers. The methodology equated the frequency of masking opportunities during (1) noise onset made contingent upon phonation, and (2) noise cessation made contingent upon phonation. A continuous noise condition and a no-noise control ... Research Article

This experiment examined the effects of continuous and contingent white noise masking upon the speech of 10 stutterers. The methodology equated the frequency of masking opportunities during (1) noise onset made contingent upon phonation, and (2) noise cessation made contingent upon phonation. A continuous noise condition and a no-noise control condition were also included. All noise conditions produced significantly less stuttering than the no-noise control condition. The three masking conditions yielded approximately the same reductions in the frequency of stuttered responses. Fluency enhancement by the various masking conditions could possibly be explained by reflex functions of the middle ear muscles.
