Vocabulary
Teach the words it keeps getting wrong.
A term on its own only fixes capitals. The spoken form is what lets VV correct what it heard — “super base” becomes Supabase, on this Mac, without a team dictionary in the cloud.
Add the correct spelling, then how you say it. Several spoken forms are fine. Matching is a token sequence, not a fuzzy cloud embedding, so it does not “helpfully” rewrite words you did not teach.
Your vocabulary is stored locally and is never uploaded. Cloud post-processing, if you enable it, receives only the terms relevant to what you just said.
Pair it with snippets when you want a whole paragraph from a short phrase.
