“…Black (1951) utilized sets of five-syllable phrases carefully matched for characteristics such as equivalence of natural intensity induced by reading them in normal conditions. Prose passages have been most commonly used, varying from relatively uncontrolled material of varying lengths (Fairbanks, 1955;Spilka, 1954b;Tiffany & Hanley, 1952) to passages which have been phonetically balanced (Spilka, 1954a), equated for difficulty level (Winchester, Gibbons, & Krebs, 1959), or chosen so as to contain all English speech sounds (Arens & Popplestone, 1959). At the other extreme, even the content has been indeterminate, as when 5 is asked to say nursery rhymes (Beaumont & Foss, 1957), or first say, and then explain the meaning of, simple proverbs (Korowbow, 1955).…”

“…Adaptation to DAF Atkinson (1953) found no adaptation of either sound pressure level or duration when 5 read a total of 60 standardized phrases. Winchester et al (1959), however, used 10 200syllable passages equated for difficulty and read under a delay of .16 sec. at 60 db.…”

“…On the whole, then, the results of these studies indicate that while some degree of adaptation does take place to continued DAF, the adaptation is not complete. Winchester et al (1959) have indicated that these adaptation effects may be prevented by increasing the feedback intensity or by changing the delay time, while Hanley et al (1958) prevented adaptation by presenting DAF intermittently.…”

When S hears his own voice with a small time delay his speech may be seriously affected. The effects produced by delayed auditory feedback (DAF) include prolongation of vowels, repetition of consonants, increased intensity of utterance, and other articulatory changes. The significance of individual differences in susceptibility to DAF is considered in relation to personality and physiological characteristics. The technique may prove useful in the detection of auditory malingering and has possible implications for the understanding of stammering. The discussion relates the findings to models of speech control. Methodological problems and future research needs are outlined. (74 ref.)

“…Chase and his co-workers (1961) reported that older children and adults are more affected than the younger ones but other recent research by MacKay (1968) does not substantiate this. Adaptation to DAF can be achieved, despite some of the earlier research (Atkinson, 1953 and Neelley, 1956)~ but usually only after prolonged exposure (Goldiamond, 1965;Winchester, Gibbons and Krebs, 1959). Some lingering effects in terms of disrupted speech has been reported by Black (1955) and others but these seem to be transient.The question has been posed as to whether or not the repetitions and prolongations shown under DAF are similar or identical with stuttering behaviors.…”

A BRIEF review of the research on delayed auditory feedback would appear tv be appropriate before proceeding to describe its utility in stuttering therapy. As now we know well, when a speaker's speech is'returned to his ears a fraction of a second after the time it normally would arrive, certain changes in his speech occur. His verbal output tends to be slowed down (Black, 1951); repetitions of syllables and prolongations of sounds are observed (Lee, 1951); the speech becomes slurred and certain sounds are distorted or omitted (Ham and Steer, 1967). The artificial stutter and the articulation errors were viewed by Fairbanks and Gunman (1958) as the primary behaviours produced by the delay. However, according to these authors, the other behaviors such as an increase in the pitch of the voice and an increase in vocal intensity together with pauses, palmar sweating and flushing were seen as reactions to the experience.It should be mentioned that there exists a wide individual variability in all these reactions, whether primary or secondary (Beaumont and FOSS, 1957). Some individuals indeed seem to be relatively unaffected by DAF : other persons show a proclivity toward repetitions while others prolong their vowels. Some react with marked pitch changes or increases in loudness; a few even demonstrate difficulty in word finding (Meyer-Epler and Luchsinger, 1965). Males seem more vulnerable than females (Bachrach, 1964). Chase and his co-workers (1961) reported that older children and adults are more affected than the younger ones but other recent research by MacKay (1968) does not substantiate this. Adaptation to DAF can be achieved, despite some of the earlier research (Atkinson, 1953 and Neelley, 1956)~ but usually only after prolonged exposure (Goldiamond, 1965;Winchester, Gibbons and Krebs, 1959). Some lingering effects in terms of disrupted speech has been reported by Black (1955) and others but these seem to be transient.The question has been posed as to whether or not the repetitions and prolongations shown under DAF are similar or identical with stuttering behaviors. Neelley's (1961) research seemed to indicate that they were not; however, Yates (1963) and others have criticized the design of his study and especially his conclusions.A rather surprising finding is that certain stutterers (Soderberg, 1969)~ especially the more severe ones, speak much better under DAF than under normal feedback conditions. Chase (1958) reported that children who showed more repetitions in their speech than normal improved in fluency under DAF. Nessel (1958) in Germany found that some stutterers spoke better under DAF; so also did Lotzman (1961) who studied 60 stutterers and used a variety of delay times. Adamzcyk (1963) in Poland, Bohr (1963) in South Africa, Zerneri (1965 in Italy, and a number of workers in the United States have demonstrated that certain stutterers speak much more fluently under DAF. A very interesting study was done by Cohen and Richards (1965). They attempted to interfere with the stutterer's presumed...
