Table 6.1: Mean F2 vowel midpoint values of the vowel /O/ according to the place of
articulation of the preceding plosive. Data broken down according to speakers,
vowel in stressed position, sentence reading task.
The observed differences are independent of vowel duration, i.e. F2 at vowel midpoint
does not raise as duration decreases. No statistically significant relationship between
duration (expressed in NoP) and F2 at vowel midpoint was observable for any of the
speakers (see Figure 6.1 and Table 6.2).
Figure 6.1: Regression lines and scatter plot of duration (number of periods) vs. F2 at vowel
midpoint of CV – sequences, where C is an alveolar plosive and V a back, stressed
vowel /O/. Reddish lines: female speakers, bluish lines: male speakers, sentence
reading task.
Table 6.2. gives the correlation coefficient r for all speakers:
Speaker p082 p129 p180 p012 p126 p127
r 0.723 0.005 0.386 0.574 0.252 0.011
Table 6.2.: r for duration (number of periods)/F2 at vowel midpoint, broken for all speakers,
stressed vowel /O/ with preceding alveolar plosive, sentence reading task, p > 0.05.
