Okay, this is under the category 'linguists I have known'.
Apparently we've had 50 years of relaxing forced articulation, 'get off' now become 'gedd off' and little difference between 'illumination' and 'elimination'. A couple of things have gone the other way. 1. The glottal stop/ glottal reinforcement had become stronger for 't', so 'a bid of bedda buda' has returned to ' a bit of better butter'. 2. Announciation for comic effect. 3. The'schwa' 'Wembley' is becoming 'Wem ba lee', 'ugly' is moving to 'ug a lee'.
So Fortean Times, 'yure nod ga wan mad, yure ex aggerly right.'
