RP

ʊə

Lower case upsilon + schwa

Falling, narrow, back centring/opening diphthong.

RP /ʊə/ glides from a tongue position similar to that used for /ʊ/ towards the more open type of /ə/ when occurring wordfinally, and to a closer variety of /ə/ word medially. The lips change from weakly rounded to neutrally spread as the glide progresses. As noted about /ɪə/, in unaccented syllables with the schwa element usually representing a suffix with morphemic status, the starting point may be pronounced as a closer and more tense vowel [ju:ə] or [uə] (e.g. influence valuable, vacuum, enventual), which seems to indicate a hiatus of the vowels in sequence. Nowadays, this glide is disappearing from RP and many other varieties of British English. It is being replaced by the long monophthong /ɔ:/.In Spanish the closest equivalent to RP /ʊə/ is the rising diphthong occurring in such words as e.g. suave 'soft', guante 'glove', in which the first element is less prominent, and second element, more prominent, more open and fronted, than in English.

Pronunciation

The tongue moves downwards from just above a half-close centralised back postion to a central half open position or even lower. The lips change from weakly rounded to neutrally spread. The soft palate is raised (unless followed by a nasal).
