Table 5.3.: Median F3 values of the first five frames calculated from vowel onset in bilabial,<br />
alveolar and velar context, stressed position, sentence reading task.<br />
Since no normal distribution can be assumed for the data, a Median Test has been<br />
performed. Two speakers (sp126 and sp082) did not differentiate the alveolar and velar<br />
context for both F2 and F3, a further speaker (sp127) did not differentiate the alveolar<br />
and velar context for F2. The bilabial and velar context was not differentiated by four<br />
speakers (sp126, sp012, sp082, and sp129) for F2, but all speakers differentiated F3 for<br />
this context pair. With the exception of speaker sp126, who did not differentiate bilabial<br />
and velar context for F2, all speakers differentiated bilabial and velar context.<br />
Therefore, the bilabial context is differentiated by all speakers, at least with respect to<br />
F3. Differentiation of alveolar and velar context is less secure.<br />
For each subject, F2 106 and F3 are lower in bilabial context. These differences<br />
hold also for stressed positions in spontaneous speech. From an articulatory point of<br />
view, the lower values for F2 and F3 point out that in many instances, there is less<br />
contact between the tongue and the palate when /i/ is preceded by a bilabial plosive than<br />
when preceded by an alveolar or a velar plosive. Thus, alveolar and velar plosives<br />
increase contact area and are more subject to palatalization than a bilabial plosive.<br />
When, then, does palatalization start? Wood (1996) could observe for Bulgarian<br />
that palatalization of the alveolar consonant started already during the vowel preceding<br />
the plosive. In order to test whether palatalization starts that early in Standard Austrian<br />
German, C1V1C2V2 sequences were chosen where C1 is an alveolar plosive /d/, V1 has a<br />
106 Except for speaker sp126, who, however, exposes no statistically significant differences<br />
for any context, i. e. consonantal contexts are completely blurred.
