Below I quote some words with unstressed e in their morphemic affixes:
- finden, with -en, an infinitival affix
- findet, with -et, a personal morpheme
- vermutete, with -ete, a (tense and personal) morpheme
My questions are as follows:
For 1., I am used to pronouncing the infinitival affix with a regular schwa but some dictionary (Oxford, really) marks this word with /ˈfɪndn̩/ as a pronunciation instruction, indicating that the unstressed sound of e in the infinitival affix be completely dropped. I am wondering is this schwa-drop a must for the pronunciation of such words?
For 2., I once heard some native speaker from München utter the unstressed e in the personal affix as a sound somewhere between [e] and [ɛ], which is definitely not a schwa, but I was taught in class to utter such e as the schwa [ə]. I am wondering whether both ways are perceived as standard pronunciation?
For 3., I was taught to pronounce both e in -ete as schwa [ə]; thus the final and the penultimate syllables get juxtaposed to form [tətə], which I feel awkward to utter because two continuous schwa-syllables make my mouth muscle too relaxed to maintain any rhythm of speech. I am wondering whether it is permissible to switch the sound of the penultimate e a bit to [e] or [ɛ], which demands more muscular effort than the schwa does, so as to keep my mouth muscle at least at a minor degree of tension, which, to me, is essential for a better sense of rhythm in speech?
