How sure the model has to be before a word counts. Raise this if background noise — typing is the usual culprit — is triggering commands; lower it if real words are getting missed. Saved in this browser only, not sent to the board.
Puts every setting back to its built-in default, including the key mapping and the startup mode, which returns to Parked. Nothing is written to the board until you save.
Unmutes the mic on page load instead of waiting for a click on the mic button. On by default. Turn this off if voice recognition causes problems in a particular browser before there is a chance to click anything — takes effect next time this page loads.
