Nonlinear, biophysically-informed speech pathology detection

Abstract:

This paper reports a simple nonlinear approach to online acoustic speech pathology detection for automatic screening purposes. Straight-forward linear preprocessing followed by two nonlinear measures, based parsimoniously upon the biophysics of speech production, combined with subsequent linear classification, achieves an overall normal/pathological detection performance of 91.4%, and over 99% with rejection of 15% ambiguous cases. This compares favourably with more complex, computationally i...
