This study focusses on effects of VCV coarticulation on the production of /r/ sounds in German. The two main variants of /r/ in contemporary New High German, apical and uvular /r/, were investigated in different vowel contexts. Acoustic and articulatory analyses were carried out separately for both variants of/r/. By means of the acoustic analysis different forms of realization (trills, taps, fricatives or approximants) were identified. The realizations within the same class of /r/-variant did not show any significant durational differences. In the articulatory analysis the coarticulation was examined. Whereas the anticipatory effects were rather weak, strong carry-over effects could be observed.
