Every once in a while I try the voice recognition by trying to speak normally to it. Normally, as is saying things like: "please set a reminder for five... umm... no I mean 6 o'clock".

Normal humans do this all the time, and if I can't do it speaking to it becomes incredibly frustrating to the point that I never want to do it again. I don't want to plan ahead what to say before I say it.

Granted, it's been a couple of years since I last tried so maybe they're better now.
