“…However, Conture and his colleagues (Colton and Conture, 1990;Conture et al, 1986) have noted that neither a hand-held procedure or neck-strap procedure for electrode positioning is inarguably better than the other for collecting EGG waveforms. 2 Rather than controlling for vocal sound-pressure level (SPL), each child was required to phonate at a comfortable loudness level.…”

“…The waveforms more accurately represented a modulation in vocal fundamental frequency (i.e., harmonic doubling), which can be found in the voices of both children and adults (Kelman, 1981; Robb and Saxman, 1988). More recently, Conture et al (1986) form• specific to both boys and girls before applying it to examine the vocal characteristics of disordered groups.…”

Vocal fold contact behavior was examined in separate groups of boys and girls through application of an electroglottograph(EGG). In general, a contact quotient (EGG duty cycle) showed minimal differences within and between boys and girls during sustained production of the vowels /i/, /u/, and /a/. The findings are discussed with respect to the laryngeal behavior of prepubescent children as well as the clinical utility and applicability of the EGG for examining phonatory behavior among young children.

“…Moreover, it has been reported that persons who stutter show disrupted motor activity in the articulatory, laryngeal, and respiratory systems during speech (Zimmerman, 1980; Conture et al, 1986; Peters and Boves, 1988; Zocchi et al, 1990; Denny and Smith, 1992; Smith et al, 1993; McClean and Runyan, 2000). There is evidence, however, that linguistic demands and changes in auditory inputs affect stuttering frequency.…”

Functional Lateralization of Speech Processing in Adults and Children Who Stutter

et al. 2011

Developmental stuttering is a speech disorder in fluency characterized by repetitions, prolongations, and silent blocks, especially in the initial parts of utterances. Although their symptoms are motor related, people who stutter show abnormal patterns of cerebral hemispheric dominance in both anterior and posterior language areas. It is unknown whether the abnormal functional lateralization in the posterior language area starts during childhood or emerges as a consequence of many years of stuttering. In order to address this issue, we measured the lateralization of hemodynamic responses in the auditory cortex during auditory speech processing in adults and children who stutter, including preschoolers, with near-infrared spectroscopy. We used the analysis–resynthesis technique to prepare two types of stimuli: (i) a phonemic contrast embedded in Japanese spoken words (/itta/ vs. /itte/) and (ii) a prosodic contrast (/itta/ vs. /itta?/). In the baseline blocks, only /itta/ tokens were presented. In phonemic contrast blocks, /itta/ and /itte/ tokens were presented pseudo-randomly, and /itta/ and /itta?/ tokens in prosodic contrast blocks. In adults and children who do not stutter, there was a clear left-hemispheric advantage for the phonemic contrast compared to the prosodic contrast. Adults and children who stutter, however, showed no significant difference between the two stimulus conditions. A subject-by-subject analysis revealed that not a single subject who stutters showed a left advantage in the phonemic contrast over the prosodic contrast condition. These results indicate that the functional lateralization for auditory speech processing is in disarray among those who stutter, even at preschool age. These results shed light on the neural pathophysiology of developmental stuttering.

“…Conture et al [4] corroborated the diffi culty in stabilizing and controlling laryngeal gestures in phonation. Stuttering individuals seem to have difficulties from the very phona tion start, which may be proved by the fre quently present irregularities of the vibratio brevis type, whose existence may be con nected with the incoordination of the respira tory muscles [5].…”

We studied the effect occurring in close proximity before the phonation start and give an account of the microdramas taking place upon the glottis immediately before the phonation start in a group of individuals suffering from balbuties (60 children and adolescents from 9 to 14 years of age) and an equally large control group suffering from no such speech defect. In the group of children and adolescents with balbuties only less than 4% of the cases showed undisturbed regular phonation starts, whereas in the control group it was almost as much as 90%.
