Nasalized open front unrounded vowel to Diphthong ou
The nasalized low vowel [ã] diphthongizes to [ou] through backing and rounding, developing a labial off-glide. This outcome is less common than [aw̃] but occurs in Romance dialects when nasalized vowels undergo diphthongization combined with denasalization. The shift represents vowel movement from low central position toward high back rounded position with glide formation.
