Use case
A first draft you can actually edit
The expensive part of a document is the blank page. Talking through what you mean produces a rough draft in the time it takes to think it, and editing beats starting.
Say it, then shape it
A spoken draft is longer and looser than a typed one, and that is the point — cutting is faster than composing. What arrives is your reasoning in your words, not a summary of it.
The vocabulary of your domain
Documents are full of client names, product names and internal jargon. The personal dictionary is where those go, and it is stored per language on your Mac.
