How You Know It's Working
Once you start captions, look for these three indicators to confirm ADA Meetings is active during your meeting:
Green "Listening" Badge
A green label with a pulsing microphone icon appears in the caption status bar. If you see "Paused" instead, captions are off.
Live Captions Appearing
As people speak, captions appear in real time with timestamps. Interim text shows in italics; finalized text appears in bold.
Caption Counter & Timer
The status bar shows a running count of finalized captions. The Transcript Panel also shows a live session duration timer.

- 5Adjust the speech rate using the rate slider (0.5x to 2x speed).
