Fundamental Frequency and Jitter Percent in MDVP and PRAAT

xlomafota13 shared this article with you from Inoreader Message: Summary Purpose This study initially investigated the relationship between Fundamental Frequency and Jitter Percent across and within MDVP and PRAAT. Subsequently, it explored if the measured acoustic signal's Length or the analysis temporal segment selection impacts potential correlation across the tools' measures. Methods We collected forty-two Maximum Phonation Time acoustic signals from 10 participants with Healthy Voices in a standardized setting. We excluded from enrollment any potential participants having a history of voice disorders or showing an abnormality in a pre-study assessment. Results There is no correlation between Jitter percent's values and Fundamental Frequency within either Tool in our healthy voice samples. The Length of the acoustic signal and temporal analysis selection impact the correlation between Jitter Percent measurements across the two tools; The correlation between Fundamental Frequency measurements across the devices was not affected. Means of Fundamental Frequency did not differ across the two devices but show a persistent pattern of greater values in MDVP. Jitter Percent measurements were significantly higher in MDVP Conclusions There is a potential for clinicians using PRAAT assessments in the clinic to make inferences from research using MDVP as an analysis tool. Further work is needed in patients with Voice disorders to explore that possibility.
