This paper provides a short introduction to the various methods available for the analysis of the voice of dysphonic patients suffering from neurological disorders. Both auditory-perceptual ratings as well as conventional acoustic perturbation measures are of limited relevance to the specific characterization of patient groups. However, the addition of further techniques such as electroglottography (EGG) as well as new methods of signal processing such as fractal dimension analysis allows to delineate characteristic profiles of performance to some degree.
