The speech recognition software is terrible. If it wants to give you a score from 0 to 100, I'm fine with that but to have to keep on repeating myself and yelling only to see "I didn't catch that try again" is more than frustrating. So I'm just skipping trying to talk into the mic for now. And my Google Chrome is updated. My mic is a very good one.
