What may come across as bad news for those who have little need for the Kinect, but enjoy using Cortana on their Windows Phone, it has been hinted in a Microsoft video that the accessory will be required for Cortana speech recognition on Xbox One.
The video can be watched by heading to the E3 featured area on the Xbox One. The video shows off the new dashboard features coming to Microsoft's console, and near the end of the video it clearly states Kinect is required for Cortana speech recognition:
"Coming Holiday 2015. Some features require Xbox Live Gold (sold separately). Kinect required for Cortana speech recognition. Cortana available in select jurisdiction only."
You can check out this video by visiting the E3 area on your Xbox One.
