To open Audio Confirmation Tone Settings use the menu Options -> Audio Confirmation Tones.

If you use Express Dictate when not watching the screen, it can be useful to have an audio confirmation when recording starts and when stopped. By default these settings are off.

Create tone when creating dictation - When a new dictation is created, a tone will sound.

Record tone when recording starts - A tone will sound when recording starts.

Stopped tone when recording stops - A tone will sound when recording is stopped.

Repeat stopped tone while not recording - This option is only available when the option above is also selected. A tone will sound as long as recording is not in progress, every few seconds.

Send tone when sending dictation - A tone will sound when a dictation is sent.

Error tone when sending and recording fails - A tone will sound if the sending of a dictation fails.
