The app keeps mishearing a ticker or term — can I teach it?

Two ways. Type the term into Personal vocabulary so transcription expects it — and when you correct a value the app set, it remembers that correction on its own.

The learned part happens without you asking. When voice fills a structured field — a dropdown, a picker, any field with a fixed list of valid values — the app watches that one field. If you change it to something else within about forty-five seconds, it takes that as heard this, meant that and stores the pair. Next time the misheard form snaps straight to what you meant, and the corrected term is fed back into transcription so it is likelier to come out right in the first place.

It only does this for structured fields. Editing a sentence in a notes box is writing, not correcting, and is ignored.

One limitation to know: there is no screen that lists your learned corrections. You cannot review, edit or remove an individual one. They are kept per browser, up to a few hundred, with the oldest dropped, and clearing that browser's site data clears them. If something has been learned wrong, correct the field once more the right way — the newest correction for a form wins.

For anything you would rather state up front than correct into place, use personal vocabulary below — the one control you can actually set for this, since corrections have no screen.
