There has been discussion about the dark L being heard as a vowel by L2 learners, though this view is often denied and corrected by L1 speakers, who point out that the dark L is indeed a consonant rather than a vowel. However, a study shows that the vocalization process is indeed completed in some areas in England (see page 13 on https://core.ac.uk/download/pdf/4187965.pdf).
Any why, in the circumstance of a vowel following the dark L, is the dark L vocalized as well (in the u-areas on the map)? For example, is "all over" pronounced as "o over" or "o-l'over". If the former, is there any other mechanism that indicates the existence of two o's rather than one, for example by a glottal stop? If the latter, can I say that English in these areas has developed liaison as in French?
In French, liaison occurs as well after a pause caused by hesitation or thinking while speaking, e.g. "les... [1 sec. pause] s'enfants" where they keep the s after the pause. Does the after-pause-liaison also happen in a sequence like "a personal... [1 sec. pause] and..." in some British English accent?
In British English, the r in the end of "worker" is not pronounced, while in the sequence "worker of", it is pronounced. So how about if there is a short pause between the two words? Is it become "worker... [pause] r'of"?
