User experience isn't confined to the layout of a webpage or the interface of a smartphone. In fact, one up-and-coming UX development is snaking its way into flying, driving, video games and much more. Voice commands have become the hot new feature in the tech world, allowing users to operate hands-free and with more ease than ever. Here are just a few examples of voice commands making waves in the UX industry.

Rockwell Collins' Advanced Technology Center has developed a high-tech flight simulation program that puts users into a replica plane cockpit. The only difference: Users have the ability to steer the digital aircraft using just their voice. According to CNN, would-be pilots hold onto a plane control stick, similar to other aircrafts. Once they say a voice command, a mechanical voice will repeat the request and the pilot hits a button to confirm. Similar speech recognition systems are already being used in some of the most advanced fighter jets, including the F-35. The news source claims voice commands may reach commercial airliners sometime in the near future.

Back on the ground in the leisure context, broader voice commands are being integrated into Sony's Playstation 4, according to CNET. In an update, the video game company claimed it addressed some of the community's most-requested features, including a wider array of voice commands. Now, gamers can say "all commands" to their headsets or directly to the console to get a comprehensive list of what the device can do with just a few orders.

Meanwhile, Google Glass applications are created on a regular basis that broaden and expand what users can do with voice commands. VentureBeat described how a recently developed application called Glass Master allows wearers to toggle audio volume, brightness, WiFi and Bluetooth with a growing amount of voice commands.
