Sylvia Moosmüller It becomes apparent from Tables 4.12 – 4.14 that the opposition between the pair /i/ – /ç/ in stressed positions is fully maintained in the logatome reading task. It is also fully maintained in stressed positions in the task of reading sentences by five of the speakers. However, the opposition in stressed positions starts to be neutralized in spontaneous speech for all speakers except speaker 129. Figure 4.11 summarizes the results of the statistical analysis: Figure 4.11: Results of the one-tailed t-tests for the vowel pair /i/ – /ç/. For each formant and each speaking task, statistically significant differences (p < 0.05) are indicated by crossbeams. Where no differences occur for a given formant, the space is left blank. Legend as in Table 4.12. Figure 4.11 shows that only two speakers distinguish the vowel pair in the stressed position in spontaneous speech; speaker sp129 distinguishes them by all three formants and speaker sp126 only by F1. In the unstressed positions, the vowel pair is, if at all, only discerned by F1. The cluster analysis presented for speaker sp012 illustrates the 90
91 Vowels in Standard Austrian German differences between the speaking tasks. Figure 4.12 presents a cluster analysis for all /i/ and /ç/ vowels in stressed positions in the task of reading sentences: Height 0 2000 4000 6000 8000 10000 12000 14000 ic12 ic15 ic13 ic14 ic16 ic17 ic03 ic01 ic02 ic05 ic08 ic19 ic04 ic20 ic21 ic07 ic06 ic18 ic09 ic10 ic11 Iuc13 Iuc14 dist(tF) hclust (*, "average") Figure 4.12: Cluster analysis of F1, F2, and F3 of all /i/ and /ç/ vowels in stressed positions. Sentence reading task. Speaker sp012. “ic” = /i/ [+constricted], “Iuc” = /ç/ [–constricted]. In Figure 4.12, the /i/ vowels are clearly kept apart from the /ç/ vowels. In unstressed positions in spontaneous speech, however, the opposition becomes totally blurred (Figure 4.13). Iuc04 Iuc16 Iuc05 Iuc02 Iuc07 Iuc10 Iuc03 Iuc09 Iuc08 Iuc12 Iuc06 Iuc11 Iuc01 Iuc15
