The same picture emerges for stressed positions in spontaneous speech (see Table 4.38):<br />
Spont. i – ç y – Y e – E ë – ê u – ï o – O<br />
Sp012 108–104 x –122* 90–95 97–87* 106–99* 91–92<br />
Sp180 190–202 185–196 162–139 149*–x 198–181 166–162<br />
Sp082 170–203 234–290* 189–178 197*–x 209–177* 186–178<br />
Sp129 186–178 188–201* 154–153 157–192* 182–181 154–155<br />
Sp126 121–118 x –114* 109–117 x –114* 120–116 110–115<br />
Sp127 123–120 110–131 114–111 113*– x 123–128 119–114<br />
Table 4.37: Mean F0 values of all vowels in stressed positions in spontaneous speech. Vowels<br />
are grouped in pairs. Within each pair, the value to the left represents the<br />
[+constricted] vowel and the value to the right the [–constricted] vowel.<br />
Statistically significant differences within each pair (p < 0.05) are marked in bold.<br />
Where the t-value is negative, the pair is additionally in italics. The asterisk<br />
indicates that no t-tests could been performed.<br />
Tables 4.36 and 4.37 show that statistically significant differences occur only<br />
sporadically, if at all. In unstressed positions, the discriminative power of F0 with<br />
respect to constriction degree is not any better. Therefore, in Standard Austrian German,<br />
F0 does not depend on tongue height.<br />
However, another grouping can be filtered out from these results, and this<br />
grouping has to do rather with constriction location rather than with constriction degree.<br />
In the front region, the pre-palatal vowels are kept apart from the mid-palatal vowels. In<br />
the back region, the pharyngeal vowels are kept apart from the velar vowels. The<br />
pharyngeal vowels might be further differentiated, insofar as the /A/ – vowels might<br />
show up lower F0 values than the /o/ – vowels.<br />
A statistically significant difference between the upper and the lower pharyngeal<br />
vowels (in the sense that the lower pharyngeal vowels expose a lower F0 than the upper<br />
pharyngeal vowels) is found in the task of reading logatomes by both speakers, in<br />
stressed positions in the task of reading sentences by speakers sp012, sp180, sp127, and<br />
in unstressed positions in the task of reading sentences by all speakers. In spontaneous<br />
speech, this distinction is displayed in both stressed and unstressed positions by all<br />
speakers.<br />
