[Evaluation of dysphonia--a multiparametric approach].

Voice evaluation is based on perceptive analysis of voice quality and on instrumental assessments, which comprise acoustic and aerodynamic sound measures. Even though perceptive evaluation is considered the gold standard for voice evaluation, it is biased by its subjective nature. Despite the fact that instrumental analysis is considered objective, it has limited reliability. This is why the integration of these two methods into a multiparametric analysis allows a more broad range diagnostic approach for dysphonia.
