Is it a spoken word, or is it spoken punctuation? Voice recognition software must discern which, and often gets it wrong. A recent example while using Dragon NaturallySpeaking:
What I actually said to my computer: amazing camaraderie
How my voice software translated it: amazing, Rotary
As you can see, it assumed that the “cama” part of the word camaraderie that I spoke was actually “comma” and inserted one, guessing the rest of the word to be Rotary. Nice try, but FAIL. Dragon has failed on the word camaraderie for me in the past, humorously so.
