“…The only partial score found to differentiate the two groups is vocal behaviour. Our data reinforce the influence of vocal behaviour on the development of dysphonia in children, corroborating the literature ( 5 , 6 , 7 , 8 , 25 ). Features such as speaking with effort, speaking without resting and imitating characters’ voices have previously been related to vocal alteration ( 26 ).…”

OBJECTIVES: The objective of the study was to establish a cut-off point for high dysphonia risk in children using the Child Dysphonia Risk Screening Protocol (DRSP-C). METHODS: Through a preliminary study, voice recordings of 59 children (4-12 years of age) were collected during an auditory-perceptual analysis using the Consensus Auditory-Perceptual Evaluation of Voice protocol. Thirty of the patients had voice disorders (patient group), and 29 did not (control group). A risk score for dysphonia was then calculated, and data were compared between groups. The relationship between overall degrees of deviation and questionnaire scores was analysed. The questionnaire’s validity was verified from the area under the Receiver Operating Characteristic (ROC) curve, and cut-off points were obtained based on diagnostic criteria for screening procedures. RESULTS: The DRSP-C score was found to be higher for the patient group, as was the partial score for vocal behaviour. No correlation was found between overall degrees of dysphonia and questionnaire scores. The area under the ROC curve was measured as 0.678, denoting limited diagnostic capacity. The cut-off point was set at 16.50. Thus, above this value, dysphonia risk is higher. CONCLUSION: A cut-off point for high dysphonia risk was calculated. The DRSP-C proved to be a promising tool for children’s clinical vocal and health promotion and should be used in conjunction with General Dysphonia Risk Screening.

“…In the groups of children and senior subjects, those without complaints and with a mild level of change were included in the NDG. A certain degree of vocal disorder can be considered normal in childhood due to disorders in the vocal tract in terms of position, size and tissue change, which affect phonatory agility and flexibility 16 , 17 . In seniors, slight vocal disorders, even without vocal complaints, may be related to physiological disorders, such as reduced vital respiratory capacity, maximum phonation time and muscle tone and atrophy of the intrinsic muscles, associated with a decreased muscular capacity to articulate speech sounds 18 .…”

OBJECTIVE:To propose and test the applicability of a dysphonia risk screening protocol with score calculation in individuals with and without dysphonia.METHOD:This descriptive cross-sectional study included 365 individuals (41 children, 142 adult women, 91 adult men and 91 seniors) divided into a dysphonic group and a non-dysphonic group. The protocol consisted of 18 questions and a score was calculated using a 10-cm visual analog scale. The measured value on the visual analog scale was added to the overall score, along with other partial scores. Speech samples allowed for analysis/assessment of the overall degree of vocal deviation and initial definition of the respective groups and after six months, the separation of the groups was confirmed using an acoustic analysis.RESULTS:The mean total scores were different between the groups in all samples. Values ranged between 37.0 and 57.85 in the dysphonic group and between 12.95 and 19.28 in the non-dysphonic group, with overall means of 46.09 and 15.55, respectively. High sensitivity and specificity were demonstrated when discriminating between the groups with the following cut-off points: 22.50 (children), 29.25 (adult women), 22.75 (adult men), and 27.10 (seniors).CONCLUSION:The protocol demonstrated high sensitivity and specificity in differentiating groups of individuals with and without dysphonia in different sample groups and is thus an effective instrument for use in voice clinics.

“…The very young, entering school for the first time, have vocal exuberance which ought to be taken in consideration by managers. Aside from speaking loudly, they tend to laugh, shout and cry a lot during their interactions 27 . In children's education, playing is the guiding force for the majority of their activities, the implications of which, is the natural rise of noise in a given environment.…”
