To clarify I am only discussing usage of voice dictation when Emacs is run in GUI mode. The use case of using voice dictation through a terminal emulator would be the responsibility of the terminal emulator and _not_ Emacs.
Of course. If you can share any hints that would enable another Emacs macOS GUI user to try dictation (my key is bound to fn and I press it twice), I'm all ears. I guess I could check out 29.4 sources and build from scratch rather than use the nix-based repeatable build I've been using. But I'm not sure what that would accomplish. I'm willing to try.
