labialise การใช้

There may also be distinct labialised consonant phonemes.
The Survey of Scottish Gaelic Dialects occasionally reports labialised forms such as or outside the area they predominantly appear in, for example in Harris and Wester Ross.
The consonant inventory is rather simple, with a labialised nasal and plosive in addition to bilabial, apico-alveolar and dorso-velar stops and nasals.
A related process is coarticulation, where one segment influences another to produce an allophonic variation, such as vowels acquiring the feature velum opens prematurely or becoming labialised as in " boot ".
It seems that the vowel system derives from an earlier one with more phonemes, but after the development of labialised consonants in the vicinity of round vowels, the vowels lost their roundedness / backness distinction, merging into just two phonemes.
