Open front unrounded vowel to Diphthong ai

The vowel [a] diphthongizes to [ai] through the insertion of a glide [i], typically as a conditioned change before specific consonant clusters or as part of larger vowel system shifts. This process occurs in both historical sound changes and modern allophonic variation, particularly before high front consonants.
