If you've got an Android 4.0 device or ROM and a burning desire to try out the latest Siri clone, you're in luck: an XDA Developers member got his or her hands on the APK for Samsung's S-Voice. This combination of Google's voice recognition engine and heuristic computing got the lion's share of the attention for the new version of TouchWiz, which debuted with the Galaxy S III earlier this month.
You'll need an Ice Cream Sandwich tablet or smartphone, but thankfully not a Samsung one, to try it out. Our quick experimentation shows that it works well enough. As far as utility goes, it's about as useful as Siri - which is to say that if you give it just the right command and you're speaking clearly in a low-volume area, it'll usually give you a vague version of the answer you're looking for. Currently it seems very inclined to give you the weather and not much else.
The post says that you'll need to copy the app into your System/App folder and alter the permissions, but I've had success with simply installing the app via the standard non-market way. At present it isn't much better than using Google's standard voice recognition with search - those of you who were hoping for a "Siri killer" will be disappointed. Here's hoping that Samsung can improve it before the Galaxy S III's European release in a couple of weeks.
