[Computer use in voice analysis: clinical applications].
Computers play an important role in voice analysis both in research and in the clinic. We have revised some basic concepts in signal digitization and some of the options present in the different voice analysis systems as: intensity and fundamental frequency measurement, perturbation calculation (jitter and shimmer) and spectrographic analysis. Clinical applications are outlined in conclusion.
