Nuance already has some solutions for speech recognition -- it's got a voice control app for both iOS and Android called Dragon Go! Now it's taking that a step further with Dragon ID, an even smarter tool that actually can decipher the sound of your voice.
You can talk to Dragon in a similar way you would with Siri on the iPhone, though Dragon is arguably more intelligent. The difference with Nuance's tool is that it actually understands you are you by identifying your specific voice. If you were to call your mother and your father picked up, you would be able to tell it was your dad without asking. Dragon has the same kind of know-how.
On top of that, it does a lot of the things you'd expect, like help you schedule meetings, make phone calls and send emails. It works in English, French, German, Italian, Spanish, Chinese, Japanese and Korean. All you have to do is say "Hello Dragon" in the language you want to use, and it understands you automatically and unlocks the phone.
The only thing is we can't actually test these cool features yet. Nuance isn't selling it through the iTunes App Store or Google Play, rather it's marketing it to OEMs who would presumably have it preloaded into future devices. So while Nuance is making the official announcement today, we don't actually know when Dragon ID will be implemented.
