Like a stubborn family member or insubordinate employee, Xbox One owners might need to tell their fancy new console what to do more than once.

In flashy commercials that began airing last week to promote Microsoft's upcoming video game system, an array of users verbally command their Xbox Ones to do stuff like answer a Skype call, fire up a "Titanfall" match or play the latest "Star Trek" film. The ads leave out one detail: They probably had to repeat themselves a couple of times for it to work.

At a demonstration of the Xbox One this week organized by Microsoft, the new version of the company's voice-and-motion-detecting Kinect sensor didn't work nearly as flawlessly in real life. The Xbox 360 successor, which is scheduled for release Nov. 22, required several commands to be repeated for the response to pop up on screen.

During a private 45-minute presentation showcasing the console's media and entertainment capabilities, about 10 of 45 voice commands issued had to be repeated by a Microsoft spokesman -- some as many as four times. Kinect didn't immediately detect such orders as "Xbox, watch ESPN" and "Xbox, Bing movies with Sandra Bullock" during the demo.
