The magic of Siri is that you don’t have to know what to say. You don’t have to say specific commands. You can say what is natural and Siri will understand – to a large extent. Here are some things I said to Siri and she understood.
Set an alarm for 8:30 AM.
Here’s her response to “Could you please reset the stopwatch?” BTW, I also got her to get the words right another time, but she still could not help with the stopwatch.
Like I said, Siri understand almost everything. For those who say she does not recognize your words – remember tihs: it works for me because I need it to work.
