Hang on a minute - both you Americans and Canadians have accents!
I realised why I couldn't find the features in my version - on the UK App Store, there is no mention of the voice features and it is turned off by default. This, presumably, is Google recognising that it just simply doesn't work for UK accents!
I tried one - the obligatory "where's the nearest Starbucks?"
Search results came back for "Williams House"
Never mind, no voice recgonition app has ever worked in the UK because of the system requirements: "requires North American accent"
Still, stop the slating. It's obviously going to get better with time, and - don't forget - it's a new feature for a
free app. So it's not like you've wasted anything for it not working...
I find it interesting that Google shows so much interest in iPhone to get this out before Android. Unless they've got a perfect Android version waiting in the wings...
