Voiced labio-velar approximant to Close front unrounded vowel

The voiced labio-velar approximant [w], particularly when functioning as the second element of a diphthong (e.g., /iw/, /uy/), can undergo vocalization and monophthongization. This process involves the absorption of the approximant into a preceding high front unrounded vowel [i], typically resulting in a lengthened [iː].
