I really haven’t played with conversation yet, but to the extent I have looked at the extensions, no, I don’t think there are any that try to collapse all the talk-y actions down to one thing handled in common.
(I’ve meant to gather my responses to @AmandaB 's question about a player who can’t communicate into an extension as a reference to overriding speech-related actions and responses, but that wouldn’t be of direct use unless one had the exact equivalent premise to What Heart Heard of, Ghost Guessed with a ghostly player who can’t speak or communicate or interact with others at all.)
