| Abstract | Recent phonological approaches incorporate phonetic principles in the motivation of phonological regularities, e.g. vowel reduction and neurtralization in unstressed position by target undershoot. So far, evidence for this hypothesis is based on impressionistic and acoustic data but noon articulatory data. The major goal of this study is to compare formant spaces and lingual positions during the production of German vowels for combined effects of stress, accent and corrective contrast. In order to identify strategies for vowel reduction independent of speaker-specific vocal-tract anatomies and individual biomechanical properties and approach similar to the Generalized Procrustes Analysis was applied to formant spaces and lingual vowel target positions. The data basis consists of the German stressed and unstressed full vowels /iːɪːyːʏ eːɛ ɛː øːœ aːa oː ɔ uː ʊ/ from seven speakers recorded by means of electromagnetic midsagittal articulography (EMMA)> Speaker normalized articulatory and formant spaces gave evidence for a greater degree of coarticulation with the consonant context for unstressed vowels as compared to stressed vowels. However, only for tense vowels could spatial reduction patterns be attributed to vowel shortening, whereas lax vowels were reduced without shortening. The results are discussed in the light of current theories of vowel reduction, i.e. target undershoot, Adaptive Dispersion Theory and Prominence Alignment. |
