text: The close back rounded vowel is almost identical featurally to the labio-velar approximant [w]. [u] alternates with [w] in certain languages, such as French, and in the diphthongs of some languages, [u̯] with the non-syllabic diacritic and [w] are used in different transcription systems to represent the same sound.
