Five groups of 10 males and 10 females each, aged 5, 7, 9, 11, and 13 yr., recited a nursery rhyme under normal delay and 113-, 226-, 306-, 403-, and 520-msec delayed auditory-feedback conditions. Speaking rate and disfluency count changes from normal delay to each delayed auditory feedback condition were calculated as indicators of reaction to delayed auditory feedback. Analyses of variance and post hoc comparisons indicated that 5-yr.-olds reacted with greater change in rate at 520-msec. delayed auditory feedback than did older subjects. Five- and 7-yr.-olds were more disfluent at 413- and 520-msec. delayed auditory feedback than were older subjects. Sex differences were found in the 7-, 11-, and 13-yr.-old groups, using speaking rate as a measure of delayed auditory-feedback reaction. No significant sex differences were noted when disfluencies were used as indicators of delayed auditory-feedback reaction.

Speaking Task

25 male stutterers and 25 male non-stutterers matched by age and speaking task, read or recited under normal and 113-, 226-, 306-, 413-, 520-msec. delayed auditory feedback conditions. Changes in speaking rate and disfluency count from normal to each delayed auditory feedback condition were calculated as indicators of reaction to delayed auditory feedback. Using an analysis of variance of difference scores for speaking rate, no significant differences were found between stutterers and non-stutterers or among the delays. An analysis of variance of disfluency difference scores showed no differences between stutterers and non-stutterers. Significant differences in disfluency reaction among delay times were found.

Delayed Auditory Feedback

This experiment was designed to test whether there are aftereffects on speech to delayed auditory feedback and whether the aftereffects, if any, are a function of the severity of disruption of speech under the feedback condition. Fifty-seven Ss, divided into three equal groups, were exposed to various combinations of delay time and intensity of feedback. Comparisons of pre- and post-sidetone responses revealed no evidence of aftereffects on speech. No relationship to induced severity of speech disruption was found.

Auditory Monitoring

The effects of interference with auditory feedback on two verbal learning tasks were studied. Twenty-seven adults without speech or hearing handicaps practiced two verbal tasks (reading comprehension and paired associate) under three auditory monitoring conditions. A synchronous auditory feedback condition provided amplified but almost simultaneous auditory feedback. To provide an irrelevant feedback condition, S’s heard their own previously recorded voices reading other material. Delayed auditory feedback provided a second experimental condition. Results confirmed that delayed auditory feedback interfered significantly with efficient verbal learning. A clear and direct relationship between the amount and relevance of verbal feedback and the efficiency of speech-based learning was demonstrated.

Female Subjects

Twenty female subjects were required to select, by the method of fractionation, the delay interval judged by them to be one-half the duration of the standard delay interval with which it was paired. The signals judged were the delay intervals between the subjects' own production of the syllable /da/ and its return via delayed auditory feedback. Ten ascending and ten descending one-half judgments were obtained for each subject at each of tie standard delay intervals of 100, 200, 400, and 800 msec. The curves for the ascending, descending, and combined ascending-descending judgments, when plotted against delay intervals in physical time, were all nearly linear with a slight positively accelerated slope. A tentative scale of subjective delay time is described and its implications for evaluating the speech response to DAF as a function of time are noted.

Significant Impairment

In an investigation into the role of auditory feedback guidance in musical performance, musically experienced subjects performed on an electronic keyboard under altered feedback conditions that included pitch and timing manipulations, as well as absence of auditory feedback. The results largely replicated the data reported by Gates and Bradshaw (1974): performance in the absence of auditory feedback showed no impairment, whereas performance under delayed auditory feedback showed significant impairment. In an extension of the Gates and Bradshaw study, however, it was found that altered pitch feedback caused little or no impairment and that altering the pitches in the delayed auditory feedback condition significantly reduced the amount of delayed auditory feedback impairment. These results show that different components of auditory feedback (pitch and timing) have separable effects on musical performance and pose a problem for theories of auditory feedback effects that do not explicitly distinguish these components.

Purpose This study explored the role of auditory feedback in the regulation of oral–nasal balance in speakers of Brazilian Portuguese. Method Twenty typical speakers of Brazilian Portuguese (10 male, 10 female) wore a Nasometer headset and headphones while continuously repeating stimuli with oral and nasal sounds. Oral–nasal balance was quantified with nasalance scores. The signals from 2 additional oral and nasal microphones were played back to the participants through the headphones. The relative loudness of the nasal channel in the mix was gradually changed, so that the speakers heard themselves as more or less nasal. Results A repeated-measures analysis of variance of the mean nasalance scores of the stimuli at baseline, minimum, and maximum nasal feedback conditions demonstrated significant effects of nasal feedback condition ( p < .0001) and stimuli ( p < .0001). Post hoc analyses demonstrated that the mean nasalance scores were lowest for the maximum nasal feedback condition. The scores of the minimum nasal feedback condition were significantly higher than 2 of 3 baseline feedback conditions. The speaking amplitude of the participants did not change between the nasal feedback conditions. Conclusions Increased nasal signal level feedback led to a compensatory adjustment in the opposite direction, confirming that oral–nasal balance is regulated by auditory feedback. However, reduced nasal signal level feedback resulted in a compensatory response that was lower in magnitude. This suggests that, even in Brazilian Portuguese, a language with phonetic and phonological vowel nasalization, decreased nasality was not perceived as critically as increased nasality by the speakers.

Rate Of Speech

The purpose of the experiment was to determine how language familiarity affects stuttering under delayed auditory feedback (DAF). In one condition we compared DAF interference in German-English bilinguals speaking their more and less familiar languages. A language familiarity effect was found: the bilinguals spoke faster and stuttered less under DAF when speaking their more familiar language. This effect was independent of both delay time and language spoken. Moreover, the slower rate in the less familiar language could not explain the language familiarity effect since instructing Ss to slow down their rate of speech decreased rather than increased their stuttering. A second condition showed that the language familiarity effect was not due to paying more attention to feedback in the less familiar language. Rather, practice or experience in producing the motor organization of speech seemed to underlie the effect of language familiarity.

Eight male and eight female Ss were required to read and speak extemporaneously under voice-masking (VM) and delayed auditory-feedback (DAF) conditions. All male Ss exhibited some degree of artificial stuttering under DAF. The speech behavior of the female Ss under DAF was much the same as under VM. Under considerable increase in side-tone intensity, the female Ss' speech behavior resembled that of the male Ss.
