“…Some of these include the presence of dysarthria [6][7][8], perception of intelligibility [9][10][11][12], and various aspects of vocal quality [13][14][15][16][17]. However, none of these reliability data were gathered within the context of a clinical/bedside swallowing examination; and, to our knowledge, no other reliability data for clinical/bedside measures exist.…”

This study investigates inter- and intrajudge reliability of a clinical examination of swallowing in adults. Several investigations have sought correlations between clinical indicators of dysphagia and the actual presence of dysphagia as determined by videofluoroscopy. Whereas some investigations have reported interjudge reliability for the videofluoroscopic measures employed, none have reported reliability for clinical measures. Without established reliability for rating clinical measures, conclusions drawn regarding the utility of a measure for detecting aspiration can be called into question. Results of the present study indicate that fewer than 50% of the measures clinicians typically employ are rated with sufficient inter- and intrajudge reliability. Measures of vocal quality and oral motor function were rated more reliably than were history measures or measures taken during trial swallows. There is a need to define more clearly the measures employed in clinical examinations and to be consistent in reporting reliability for clinical measures of swallowing function in future research.

“…The efficacy of its results depends heavily on the evaluator's experience 1,[4][5][6] . Although it is considered as a gold standard for vocal evaluation, there is constant mention of possible interferences arising from the subjectivity of evaluators, lack of reliability of judgments, variety of evaluation methods, inconsistencies of instruments and lack of standardization of the terminology used 1,4,[7][8][9][10] . The search for overcoming such limitations is based on different strategies, such as presentation of anchor stimuli, training and calibration of evaluators, repetition of stimuli, application of scripts to randomize the order of presentation of speech samples (programming applicable to open source software), and a statistical approach of perceptual judgments 6,[11][12][13] .…”

Vocal quality assessment: methodological approach for a perceptive data analysis

Purpose: to present a methodological approach for interpreting perceptual judgments of vocal quality by a group of evaluators who used the script Vocal Profile Analysis Scheme. Methods: cross-sectional study based on 90 speech samples from 25 female teachers with voice disorders and/or laryngeal changes. Prior to the perceptual judgment, we performed three perceptual tasks to select samples which were then presented to five evaluators using the Experiment script MFC 3.2 (software PRAAT). Next, we applied a sequence of tests based on successive approaches to inter-and intra-evaluator behavior. Data were treated by statistical analysis (Cochran and Selenor tests).Results: with respect to the analysis of the evaluators' performance, it was possible to define those that presented the best results, in terms of reliability and proximity of analyses, compared to the most experienced evaluator, excluding one. The results of the cluster analysis also allowed designing a voice quality profile of the group of speakers studied. Conclusions: the proposal of a methodological approach allowed defining evaluators whose judgments were based on phonetic knowledge, and drawing a vocal quality profile of the group of samples analyzed.
