Table 1 Summary of disordered voice classification results. Summary of disordered voice classification task performance results, for several different combinations of the new measures, the derived irregularity (Irreg) and noise (Noise) components of Michaelis [4], and traditional perturbation measures, jitter (Jitt), shimmer (Shim) and noise-to-harmonics ratio (NHR). The RPDE parameters were the same as for figure 4. and the DFA parameters were the same as for figure 5.
