Diphthong au to Mid central vowel

The diphthong [aʊ] reduces to schwa [ə] in unstressed syllables, a phonetically natural process where the complex articulation of the diphthong simplifies to the neutral schwa vowel. This is a stress-conditioned reduction pattern documented across Germanic languages.
