At the time of writing, speaking has 21 questions, and spoken-language has 17 questions. Looking through those questions, I can't seem to tell why one would choose one of the tags over the other (besides typing "speak" versus "spoke" into the tag-selection box). The tag wikis don't seem to help me disambiguate these, either.
Should there be a difference between these two tags (and if so, what?), or should one be synonymized to the other?
Looking at the tag wiki descriptions, there doesn't seem to be any difference. I suggest we keep spoken-language.
However, not everything tagged speaking should be merged into spoken-language, as it seems some would be better under something like pronunciation, pitch-accent or similar.
In most cases questions under speaking appear to have have other appropriate tags already attached, so perhaps the best thing to do would be to remove speaking from those questions, then make speaking a synonym of spoken-language.
As there aren't that many questions, I'm happy to run through the list and do some retag edits if the rest of the community agree to this plan.
