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.

Internal Division

Jacques Derrida’s early critique of Husserlian phenomenology discusses the production of the ‘phenomenological voice’ as the consummate model of human consciousness. Challenging Husserl’s conviction that consciousness is produced from the self-enclosed act of ‘hearing-oneself-speak’, Derrida points to vocality as the complex site of the self’s relationship to presence and exteriority. The internal division between hearing and speaking, he argues, introduces difference into the generation of conscious life. The use of delayed auditory feedback (DAF) as a prosthetic for stuttering provides an opportunity to engage Derrida’s insights on the connection between consciousness and voice with an ear to the speech of people who stutter. DAF, which may reduce or increase dysfluency depending on the speech of the user, introduces a series of delays, alterations and supplements to speech that underwrite the heterogeneous experience of conscious life. What can the philosophy of deconstruction add to conversations about the function of DAF, and what can theory about and experiences with DAF teach us about the self’s presence to itself and the role of alterity in shaping speech? What does stuttering teach us about the necessity of dysfluency for all speech? This article examines the relation between the voice and the phenomenological voice, and between stuttering and prosthetics. Concluding with an analysis of Richard Serra’s experimental recording, Boomerang (1974), it argues that voice is always already prostheticized with alterity, and that in hearing-oneself-speak we exist with voice in an expansive and unfinished conversation with our own mystery.
