What are the chime and audio feedback settings?

Two opt-in confirmations under Command feedback — a short chime when a spoken command matches, and an operating-system notification when the tab is in the background.

Both are off by default and both answer the same question: did that command land, when I was not looking at the screen?

Audio chime on command match plays a brief tone the moment a command is recognised. It is synthesised by the browser — there is no sound file to install and nothing is downloaded. A Test button appears beside it once it is on, so you can hear it without saying anything.

OS notification when tab is backgrounded posts a normal desktop notification instead. This one needs your browser's notification permission; if you decline the prompt the setting switches itself back off rather than pretending to be on.

Useful when you are working in your trading platform with the app behind it — which is most of the time voice is worth using.
