Conditioning factors in external sandhi : an EPG study of English /l/ vocalisation.

By James M Scobbie, Marianne Pouplier and Alan A Wrench


English l-sandhi involves an allophonic alternation\ud in alveolar contact for word-final /l/ in connected\ud speech [4]. EPG data for five Scottish Standard\ud English and five Southern Standard British English\ud speakers shows that there is individual and\ud dialectal variation in contact patterns. We analysed\ud vocalisation rate (% of tokens with no alveolar\ud contact) and the area of any residual alveolar\ud contact. Word-final /l/ contact is, to some extent,\ud onset-like before vowel-initial words and coda-like\ud before words with a labial onset C. If the vowel\ud has a glottal attack, however, or the onset C is /h/,\ud sandhi is less predictable, suggesting that\ud resyllabification is insufficient as a mechanism for\ud conditioning tongue tip behaviour of word final /l/
