Diphthong ou to Mid central vowel

The diphthong [oʊ] reduces to schwa [ə] in unstressed syllables through stress-conditioned vowel reduction. This process is well-documented in English and other Germanic languages, where unstressed syllables favor the phonetically economical schwa over full vowel articulation.

Phonetic Effects

Centralization, Vowel Reduction

Language Examples

[boʊ]→[bə]— Words like 'bow' in unstressed contexts show reduction of [oʊ] to schwa in connected speech.
[goʊ]→[ɡə]— Reduction documented in rapid speech where unstressed syllables are centralized to schwa.
