I'd like to use remaining time to trigger an action. I'd like to launch an audio file that announces "1 minute" when there's 1 minute remaining, then "30 seconds", "20 seconds" and then a 10 second countdown, "10, 9, 8, 7, 6, etc..."

Ideally, I'd like to even be able to tap into the timecode over OSC so I can have another app (Octopus) trigger these actions.
