Kurt'The CyberGuy' Knutsson shows the best way to take voice control selfies. How cool would it be if you could just say "Cheese!" and voilà, your phone would capture the perfect selfie without you ever lifting a finger? Oh yes, you heard that right. Aside from selfies, there are several other benefits of setting up a voice-controlled camera. It can capture speech much faster than you can type.

Amazon's Echo smart speakers just went in an unusual (but potentially very helpful) new direction. Meet Echo Look, an Alexa-powered camera designed around taking your own fashion photos and videos. If you want to show off your daily wardrobe, you just have to ask the Look to take a snapshot -- you don't have to take a selfie in front of a mirror to get a full-length picture. And since it includes a depth-sensing camera, it can blur the background to make shots pop. The real party tricks come when you're not sure about your outfit, however.

One of the reasons we gave both of GoPro's new cameras -- the Hero5 Black and Hero Session -- good scores is that they both allow you to use voice control to do things like start and stop recording, take photo bursts, set a highlight tag, shoot pictures, change modes and switch the camera off. In our tests, we found that the feature works well, although on blustery days wind noise can prevent the camera's microphones from picking up the sound of your voice. In part to address that sort of problem, GoPro just unveiled the Remo, a voice-controlled remote meant to be used with its new voice-controlled cameras. Like the Hero5 Black itself, the clip-on remote is waterproof, albeit to 16 feet here instead of 33. It also responds to the same commands as the two cameras, in 10 languages. In addition to controlling for wind noise, you might clip it to pets or small children and start a recording from afar.
