Figure 5.13: Density plot of the mean values of F2 and F3 of the first five frames calculated
from vowel onset of all /i/ vowels in stressed position, speaker sp127, sentence
reading task. Red lines: C = bilabial, black lines: C = alveolar, blue lines: C =
velar.
From Figure 5.13 it can be read that:
� F2 exposes no statistically significant differences with respect to the
alveolar and velar context (p > 0.05) 105 ,
� F2 in bilabial and velar context as well as F3 in all contexts exposes two
peaks in the distribution,
105
As can be seen from Figure 5.13, no normal distribution can be assumed. Therefore, a
Median Test has been performed.
