I fixed the A'kin entry a while ago by copying the one with the variant apostrophe and adding to the regular A'kin's keywords.
I'm sure the problem was someone copying the word A'kin from Microsoft Word, which uses non-standard apostrophes and commas.
We can easily link to the appropriate sound file in each entry, assuming it won't eat up too much bandwidth.
I would have no idea how to do something like that
