Watch how Cortana stacks up to Google Voice and Siri in this 50-phrase demo video
After the 50 Google Now and 50 Siri questions, now comes the time for Microsoft's voice-activated virtual assistant Cortana to shine. Coming with Windows Phone 8.1 handsets in a limited beta availability (US, UK and China for now), Cortana proves to be a rather capable voice assistant, rivaling Google Now and Siri.
That's undoubtedly thanks to Microsoft's multi-year research in the field of voice recognition, artificial intelligence, and direct translation, but don't take our word for it, see for yourself in the video below. We've also included the 50-phrase Google Now and Siri videos for direct comparison.
