Msec Delay

Two experiments were conducted to determine whether the auditory feedback monitoring system for speech is operative in children between two and three years of age. The procedure involved a 200 msec delay in the auditory feedback of the subject’s speech. Bilateral signal presentation was used for the synchronous (SAF) and delay (DAF) conditions. Phonation time scores under DAF and SAF conditions were compared. In Experiment I, 10 subjects, ages 2 years, 4 months to 2 years, 11 months, followed a standard object naming task. Speech samples obtained from a younger group of 5 subjects in Experiment II, ages 1 year, 9 months to 2 years, 2 months, consisted of all verbal responses which occurred under both DAF and SAF conditions. The results of Experiment I provide evidence that the auditory feedback monitoring system for speech is operative in this age group. The speech of the younger subjects in Experiment II was not strongly affected by the time delay in auditory feedback. The results of the present experiments, together with findings obtained in an earlier study with four- to nine-year-old subjects, suggest that older children show greater DAF effects than younger children.

Delay Times

Binaurally asynchronous delayed auditory feedback (DAF) was compared with synchronous DAF in 80 normal subjects. Asynchronous DAF (0.10 sec difference) did not yield results different from those obtained under synchronous DAF with a 0.20 sec delay interval, an interval characteristically resulting in maximum disruptions in speech.

Clinical Program

Operant speech fluency techniques are being used in a clinical program in a rehabilitation center to treat people who stutter. Establishment, transfer, and maintenance programs are used. Delayed auditory feedback is commonly employed to produce the initial fluent speech. From more than 200 clients seen over the past four years, 50 recent clients were selected for a detailed analysis. The results indicate that the programs are effective in helping people of varying ages and stuttering severity to speak fluently. This was accomplished in relatively short periods (approximately 20 hours of therapy). The fluent speech of the clients has transferred to their environment and checks indicate that it has been maintained.

Experimental Treatments

Twenty adult stutterers were exposed to each of five experimental treatments: time-out, noise, delayed auditory feedback (DAF), “wrong” and metronome. In each session a subject spoke for 20 minutes without treatment (baserate) followed by 30 minutes in one of the five experimental conditions. Before the five treatment sessions, subjects accomplished three pre-experimental tasks: expectancy, changeability, and adaptation tasks. Percent stuttering decreased significantly in all conditions, and stuttering duration reduced significantly in all but the noise condition. The amount of reduction in percent stuttering from baserate to treatment (change score) in time-out was positively related to the change scores in DAF and metronome. Change scores in metronome were positively related to change scores in time-out and “wrong.” Percent stuttering change scores in noise, DAF, and “wrong” were essentially unrelated. Stuttering duration change scores were related only for the time-out and DAF, and metronome and DAF conditions. In general, the pre-experimental expectancy, changeability, and adaptation scores were unrelated to change scores in any of the experimental conditions. Words spoken per minute did not change significantly from baserate to treatment for any experimental condition except time-out.
