Abstract
It is the purpose in this article to review and evaluate the existing research on delayed auditory feedback (DAF) with respect to: (1) the general effects of DAF on the speech of normal man, (2) DAF-effect on native and foreign languages, and verbal facility, (3) laterality differences, (cerebral dominance) in the auditory feedback control of speech, (4) age-linked changes of auditory feedback monitoring, (5) adaptation to DAF, (6) the speech behavior of stutterers under delayed condition, (7) hearing loss, sex differences and other physiological changes in reaction to DAF.From these studies the following conclusions were drawn. The main effects of DAF is prolongation of vowels. articulatory error and increase in vocal intensity. DAF has smaller effects onn speech when reading difficult than when reading easy passages. The experiment showed the differences between both ears in aural functon during anditory feedback control of speech. The delay time for maximal DAF-effects varies with age. While some degree of adaptation takes place to continued DAF, it is not complete. Under DAF the frequency of stuttering is reduced. It is possible to use DAF as a predictor of hearing threshold test. Sex differences in reaction to DAF are observed.
