Abstract(s)
A synthesized speech signal was used to measure the accuracy of the Jitter and Shimmer parameters calculated by a previously
presented algorithm. The formant model of speech synthesis was used to produce speech signals with a controlled glottal periods
and magnitudes according to previously determined Jitter and Shimmer parameters values. The Jitter parameters (jitta, jitter, rap
and ppq5) and the Shimmer parameters (ShdB, Shim, apq3 and apq5) were calculated with a previously developed algorithm and
compared with the analytic determined values and also with measures made with Praat software. Experiments with different type
of jitter and shimmer perturbations and with different F0 values were conducted. Also the influence of F0 variations on Shimmer
and Jitter measures was experimented.
