### Parametrical Analysis of Laryngeal Articulations Based on the EGG Signal  
Tables 3 and 4 show the mean (MEAN), standard error of mean (STD), minimum (MIN), and maximum (MAX) values of parameters LA1 dur, LA2 dur, LA1 LA2 dur, LA1 peak2 rms, and LA2 peak2 rms, and the number of annotated laryngeal articulations (N). The 250 annotated laryngeal articulations occurred in a short time for all participants (mean values of LA1 dur = 144 \(\pm\) 53 ms and LA2 dur = 160 \(\pm\) 64 ms), much less than the 10 s required for a Valsalva manoeuvre to occur [(4) (p. 139)]. The value of LA1 LA2 dur was 201 \(\pm\) 134 ms, the mean peak-magnitude-to-RMS ratio (crest factor) of the EGG signal was 1.856 \(\pm\) 0.292, calculated for the interval LA1 (LA1 peak2 rms), and was 1.961 \(\pm\) 0.366 for the interval LA2 (LA2 peak2 rms). Raw Supplementary Materials Files with all laryngeal articulations durations can be downloaded from the publisher's website. Figure 9: The EGG signals for the 11 laryngeal articulations produced by male participant DO. Further analysis, considering the six repetitions of each participant, revealed a Pearson's correlation of 0.079. The dispersion of these data, clearly shown in Figure 10, does not permit the drawing of a straight ascending or descending line through the marked points corresponding to each participant, leading us to conclude that there is no linear correlation between the answers of the two listeners. Correlations between all measurements (LA1 dur, LA2 dur, LA1 LA2 dur, LA1 peak2 rms, and LA2 peak2 rms) and the scores assigned by the listeners (total of 250 pairs of observations for each listener) were also calculated, as shown in Table 6. \begin{table}
