For instance, she'll separate out conversations:

>> Can you move the mic closer to your mouth? >> Yes. Is this better? Is this better? Okay. I will talk like this, then. >> You can move the mic. >> Like... >> Take it off the stand and hold it up to your face.

She can also figure out when something is an acronym (like LARP), make sure everything is capitalized correctly (Python, Ruby), separate out what's being said into paragraphs when the speaker starts talking about something new, and a ton of other things.
