Thanks.
(As regards Trudgill, I'd never considered any other possibility. But then I'm not a native speaker ...)
 
Urban
 
Labov (American) [l@'bAv]
Ladefoged (British, though UCLA-based) ['ladI,f@UgId]
 
IPA:
US [lə'bαv], UK [lə'bɒv]
UK ['lædɪˌfəʊgɪd], US ['læɾəˌfoʊgəd]
 
BTW, there is a famous British dialectologist and phonetician called Peter Trudgill ['tɹʌdgɪl]. I've met native speakers of English who didn't know how to pronounce his surname (a dialectal version of "treadle").
