Applescript Good Morning abort feature

So I have this really long script and I'm using dragon dictate to trigger the script to activate and the script says good morning and tells me the weather, reads me any new emails, tells me my agenda for today, reads me news headlines from specific rss feeds, and tells me the current time. I'm using a revolabs usb mic to do it and was wondering if there was a way to say "abort" or some other trigger word to stop the computer from mid way through?

It'd be quite helpful.
