## 3 Results  
The three raters' measurements for the first and last oscillation, also the first and last contact were within the limits of +/ - 18 frames based on the Wald 99% confidence interval. The following is based on what the raters and evaluators concluded as the reasons for their agreement/disagreement with the measurements. More agreement was observed in the measurement of the contact frame number than in the oscillation frame number. More \begin{table}

Table 2: Study inclusion criteria. discrepancies in the measurement of the oscillation frame number were found at the offsets of vocalization than at the onsets. The raters were found to be more in agreement when they went further in the analysis of one participant's data. Generally, more agreement was observed for the measurements of normophonic voices. One of the challenges in the measurement of the disordered voices was determining whether an onset belonged to a new phonation or that there was a delayed onset due to a phonatory break during the same phonation. In the measurements by Rater 1, in several instances, a continuation of phonation after an obstruction of the vocal folds was considered as a new phonation by mistake, which was more apparent for the disordered participants. The partial obstructions of the view of the vocal folds during phonation were found to be the main source of missing measurements by some raters. Both Rater 1 and 2 found Rater 3's measurements more accurate for the four participants. Rater 3 adjusted her measurements further during the consensus meeting with the other raters. Rater 3 completed the analysis of the remaining participants considering what she had learned during the consensus meeting. The average GAT in the normophonic group varied from 13.5 to 15.4 ms, and from 11.2 to 22.3 ms for the AdSD group (Figures 1 and 2). The AdSD group showed much greater variability for the GAT compared to the normophonic group: the average coefficient of variability (CV = std/mean \(\times\) 100) for the AdSD group was 73% compared to 45% for the normophonic group. Greater variability in the AdSD group in comparison with the normophonic group was also observed for the GOTs with an average CV of 70% for the AdSD group vs. 44% for the normophonic group. The AdSD group had higher average GAT values (16.8 ms) than the normophonic group (14.7 ms), but there was no statistically significant difference. The GOT values ranged between 23.7 and 31.5 ms for the normophonic group and between 17.4 and 30.5 ms for the AdSD group. Although the average GOT was slightly higher in the normophonic group (26.4 ms) than in the AdSD group (25.4 ms), no statistically significant difference was observed.
