“…A survey focusing on reliability found that more experienced listeners tend to be more consistent in their assessments than untrained evaluators (20) . Another study also found good intra-and interevaluators voice specialists with clinical experience (28) . The research proposes that hearing can and should be trained clinically, to improve the scores obtained in the evaluation (29,30) .…”

“…It has been validated in different languages demonstrating high diagnostic accuracy and presenting variated threshold values to identify voices with and without vocal deviation. In addition, there is more than one AVQI version (first version, 02.01 and 03.01), and each of its versions also presents different thresholds [20-28].…”

“…Reading a standardized text is not appropriate in some clinical institutions, for example where the focus is on paediatric patients or where fluent reading is simply not possible for some of the population. These issues significantly limit the validity of recommending using such texts for acoustic analysis of continuous speech [9,10].…”
