Some spectral transition features are introduced and tested in samples from dysarthric patients. The goal is to explore their potential as descriptors of articulatory deviations. This preliminary analysis includes only stop consonants extracted from the diadochokinetic task. Results and discussion are detailed for each one of the dysarthric groups included in the experiment.
Index Terms. Articulation, dysarthria, spectral transitions
