Interne Validität des Acoustic Voice Quality Index Version 03.01 und des Acoustic Breathiness Index

Abstract

The present results showed that AVQI version 03.01 und ABI had a high internal validity to assess voice changes after voice therapy. AVQI and ABI are two valid and robust voice measures to objectify hoarseness and breathiness.

Diagnostic Accuracy of Dysphonia Classification of DSI and AVQI

“…Further investigations about AVQI revealed consistent and acceptable diagnostic precision, 7,28-38 consistent and high concurrent validity, 7,28-39 robust interlanguage phonetic differences, [29][30][31][32][33][34][37][38][39] testretest variability about 0.54 for the second AVQI version, 40 independence of the influencing factors of age and gender, 25 and high sensitivity to voice changes across voice therapy. 28,32,41 The comparison and correlation between laryngeal imaging and other clinical methods are important to interpret the results of the techniques and increase their clinical relevance. [42][43][44] To what extent the comparison between a sign (e.g., abnormal value of the DSI and AVQI) and a voice pathology (e.g., abnormal results of laryngeal imaging, history, and complaints) addressed the research question might be valuable, for example, for a screening process that enables a quantification of abnormality and then pre-to posttreatment change.…”
