Samsung’s S Voice is the closest and best replica of Apple’s Siri, it does still need some tweaking and refining but it is a great start. S Voice was announced at Samsung’s press conference on the Samsung Galaxy S III on May 3rd 2012. It has been leaked to users who have Ice Cream Sandwich installed on their Android phones. S Voice works on my Cyanogen Mod port for my Droid Bionic but not all of the features work for me, and this could be due to the fact it was created for a Samsung device running Samsung’s Ice Cream Sandwich rom, it still works for 95% of the features which is fine for me.
