Vowels in Standard Austrian German<br />

monophthongized, realized in this case as /E/ 34 . Especially in the weak prosodic<br />

position, Standard Austrian German shows a strong tendency towards monophthonizing<br />

both phonological diphthongs and diphthongs derived from phonological processes (for<br />

an analysis of Austrian German diphthongs, see Moosmüller 1997b, c, Vollmann &<br />

Moosmüller 1999, Moosmüller & Vollmann 2000, 2002).<br />

The sequence lateral – vowel might cause some problems as well (see Figure 2.3).<br />

Usually, the segment border between lateral and vowel is detectable by a higher<br />

amplitude for the vowel and, for some speakers, by a plosion at the point where the<br />

tongue is adjusted for the vowel. However, sometimes, the transition is quite<br />

monotonous; in these cases, an inaccuracy of ± one period is accepted. Figure 2.3 gives<br />

34 There are many possibilities for realizing the phonetic output of the monophthongization<br />

process, even within one speaker’s output (see Moosmüller 1997a).
