At a certain point in a macro I have to determine whether shifting the final consonant(s) of one syllable to the next syllable results in a valid onset. Can anyone point me to a complete list of initial clusters for a given dialect, preferably standard southern UK English? I have looked but am only finding examples (and they're examples of orthographic clusters, when I want IPA). I can make my own list of course but would like to check I haven't missed anything.
