A correlational study of the reliability of acoustic voice parameters was made of 148 healthy adults. Acoustic analysis was performed with MDVP-Multi-Dimensional Voice Program implemented in a CSL-Computerized Speech Lab of Kay Elemetrics. A set of 29 voice parameters were obtained from two samples of sustained vowel /a/ recorded from each subject. General results separated by sex are showed and the test-retest reliability in each pair of measures was calculated. Data show a high intra-subject stability of Frequency Fundamental parameters; acceptable stability in parameters of Frequency and Amplitude Perturbation, Noise, Subharmonics and Voice irregularities; and a very low consistency in Tremor parameters. Parameters related with shimmer were more reliable than parameters related with jitter. According to results several conclusions are reported.
