Apologies. Still getting the hang of things here. I used `M-x 
submit-emacs-patch`, which created new bug.

I looked at changes for v30 and narrowed the regression down to 
this change:

https://lists.gnu.org/archive/html/bug-gnu-emacs/2024-07/msg01310.html

To fix macOS dictation, we have two options:

1. Roll back the patch from msg01310 (migrating to 
NSTextInputClient) and re-introduce the warning.
2. Roll forward with a fix on top of the NSTextInputClient 
migration.

My patch is for 2.

Pressing a keyboard shortcut on macOS temporarily enables 
dictation for any app, so you can speak and transcribe text into 
an Emacs buffer. Attaching demo (speech is muted).
