The battle for best smartphone rages on between Apple and Samsung with voice command features front-and-centre in both the iPhone 4S and the Galaxy SII.
One of the most distinguishing features of the iPhone 4S is Siri - a voice-operated 'personal assistant' that lets users speak to their phones to send messages, ask questions, place phone calls and more.
Samsung's Virtual Assistant - powered by Vlingo - works in much the same way. When users double-tap the home screen button they are greeted with an automated voice asking "What would you like to do?"
Vlingo said of its Virtual Assistant in a blog post: "Voice talk enables users to do social updates, messaging, email, hands-free communication via InCar, voice dialling and search and more.
"They will also be able to initiate commands simple by double-tapping the home screen button, making it easier than ever to get things done while on the go."
Samsung announced its 'major partnership' with Vlingo - the brains behind Virtual Assistant - just four weeks before the latest version of its flagship smartphone - the Galaxy SII - launched.
Vlingo's technology, built on the back of software from another partnership with Google, has been pre-installed in every Galaxy SII smartphone and, unlike Siri, gives users no opportunity to turn it off.
While since the launch of the iPhone 4S Siri has received a lot of attention and a largely positive reception, according to the Guardian, Galaxy users are growing irritated with their virtual assistant.
Apple users who've grown tired of Siri can silence the voice-command assistant with the touch of a button, but Galaxy users aren't so lucky, and users who accidentally activate the Virtual Assistant are left pounding their touchscreens in frustration.
