Diphthong ei to Close front rounded vowel

The diphthong /ei/, typically pronounced as a glide from a mid-front unrounded vowel to a close-front unrounded vowel, can undergo a transformation into the close front rounded vowel /y/. This shift involves two primary phonetic changes: monophthongization, where the diphthong simplifies into a single vowel, followed by rounding of that vowel.
