If you would like to experience voice recognition like Siri on your Samsung's Android smartphones, In CES, Samsung opened its dedicated voice recognition App, 'Dragon Go' by Nuance (www.nuance.com) who is a provider of Siri to Apple. In my experience, this 'Dragon Go' could be installed only in Samsung Galaxy.
