Figure 4.6: Cluster analysis for number of periods of long/tense and short/lax vowels in
stressed positions, speaker sp180, logatome reading task. All short/lax vowels are
grouped in the left box, all long/tense vowels in the right box.
It can be seen from the lengths of the vertical lines (indicating the distances to the other
cluster members 63 ) in Figure 4.6, that the distances among the long/tense vowels are
much higher than the distances among the short/lax vowels. Again, for speaker sp012;
vowels labeled “tense” have a higher amount of NoP than vowels labeled “lax” (18 vs.
9, n = 273, t = 36.18, p = 0.00), the vowel /a/ is differentiated for NoP as well (18 vs. 9,
n = 36, t = 17.24, p = 0.00). Figure 4.7 shows the cluster analysis for speaker sp012.
63 The distances, of course, contain no information about NoP.
