Abstract

In this work, the amplitude-frequency graphs provided by Hilbert's marginal spectrum are used to characterize both healthy voice signals as those with vocal deviations: roughness, breathiness and strain. The results demonstrate that the obtained patterns seem to be appropriate to differentiate the analyzed signals.
