Nuance has some solutions for speech recognition, and they've got voice control for both iOS and Android called Dragon Go! Now, with Dragon ID, they have 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, but Dragon is definitely more intelligent. The difference is Nuance's tool is that it actually understands you by identifying your specific voice. Dragon has that kind of know-how.
It'll also do a lot of things you'd expect it to do, like a Siri, like schedule meetings, making phone calls and sending emails. It works in not just English but also German, Italian, French, Spanish, Chinese, Japanese and Korean. Just say "Hello Dragon" in the language you want to use and it will automatically understand you.
Nuance isn't selling it through the App Store or Google Play, rather it's marketing it to OEMs who would presumably have it pre-loaded into future devices. So for now, we won't actually know when Dragon ID will be implemented.
