I'm English, but I've lived in the US since I was 14, which means often I have an American accent. Apparently the American Siri (she) can't understand a damned word I say, regardless of which accent I use. Probably a 4/10.

The UK Siri (he) understands me on an 8/10 I guess. There's still some things that just don't make sense.
 
For some reason the UK guy doesn't understand anything I say in texts at all.
 
hmm I'd have to say 5 only because I speak way too fast, and sometimes have to remind myself to slow it down LOL
