From: Exploiting Nonlinear Recurrence and Fractal Scaling Properties for Voice Disorder Detection

Selected normal and disordered speech signal examples. Discrete-time signals from (a) one normal (JMC1NAL) and (b) one disordered (JXS01AN) speech signal from the Kay Elernetrics database. For clarity only a small section is shown (1500 samples).
