Diphthong ei to Mid central vowel

The diphthong [eɪ] reduces to schwa [ə] in unstressed syllables, a stress-conditioned vowel reduction process common in Germanic languages. This reflects the phonetic economy of rapid speech, where full diphthongal articulation is replaced by the neutral schwa vowel in weak positions.
