iOS: ShutterVox is a unique take on the smartphone camera in that it has no shutter button at all. Instead, it listens for specific trigger words before it’ll take the photo. All you have to do is tell your subjects to say “cheese!” loudly and ShutterVox will know what to do.And loudly is key. Because ShutterVox doesn’t have sensitivity adjustments, you have to be pretty loud. I was next to the phone and had to yell “cheese!” for it to register. (Fortunately my neighbours already have reason to believe I’m crazy, so I’m guessing this didn’t change much.) This leads me to believe that ShutterVox will work better when you have a large group yelling the word and not just an individual. Even with that disadvantage, it was really good at distinguishing between cheese and other words. Yelling cake, for example, had no effect. If you don’t like cheese, ShutterVox also supports the recognition of popsicle, doodle and snap. While the concept is a little bit gimmicky, as pushing a button is probably easier, this can be a really good method of getting a very still shot when needed. ShutterVox probably won’t be your primary camera, but it could be good in a pinch.
