I'll start it first
cook, even the voice from the google translate can't make it.. Instead, it recognizes it as call, sounds like Japanese accents, walk -> wok (not trying to be racist, I'm asian)
Siri doesn't like how fast I talk. I get a lot of jumbled up words sometimes, but they surprisingly are spelled just how I pronounce them. I actually think it's helping me slow down some when talking to people.
I couldn't get her to recognize the word "stew". It kept writing "do", or if I emphasized the "s", she would write "s' do". Really frustrating. After about 10 tries, I gave up and said "soup".
