Front, closing and wide.
The glide of RP/ɔɪ/ begins at a central position, between half-open and half-close, and moves in the direction of RP /ɪ/ nearer to a centralised half-close position [ё˕]. There is a slight closing movement of the lower jaw, and the lips are neutral for the first element but have a tendency to round on the second segment. The starting point may have a tongue position similar to RP /ɒ/. Before [ɫ], the second segment tends to be absorbed into [ə] or [ʊ] glide (e.g. boil [bɔ:əɫ]). On the other hand, RP/ɔɪ/ has an equivalent glide in Spanish as in e.g. voy (Span. 'I go'), although as usual, in English the first element is more open and the second more relaxed.
