Abstract
Jitter and shimmer are measures of the fundamental frequency and amplitude cycle-to-cycle variations,
respectively. Both features have been largely used for the description of pathological voices, and since they
characterise some aspects concerning particular voices, they are expected to have a certain degree of speaker
specificity. In the current work, jitter and shimmer are successfully used in a speaker verification experiment.
Moreover, both measures are combined with spectral and prosodic features using several types of
normalisation and fusion techniques in order to obtain better verification results. The overall speaker
verification system is also improved by using histogram equalisation as a normalisation technique previous to
fusing the features by support vector machines.
