It's not just death and taxes that are inevitable. If you're writing realtime, bloopers will happen. You can't prevent them, but you can plan ahead and lessen their impact.
Conflicts often involve a common word and a very uncommon word.
Many court reporters deal with such conflicts by simply leaving out the uncommon word. In captioning or CART, though, anything can come up. You never know what bizarre words will be used in a newscast or a college class. Putting them all in often interferes with briefs, but it's better to be safe than sorry. Better to write it out and get it right than brief it and end up with an embarrassing blooper.
