The paper describes acoustic features of stressed vowel phonemes in prepared German speaking. Frequencies of both formants FI and FII of long and short stressed vowels are under consideration. The results of spectral analysis prove the tendency to centralization of all vowels. The formant areas of vowels [i:], [e:], [o:], [u:] can intersect, what can cause the vowels alternations [įe] = [ȩ:i], [ųo] = [ϙu].
