ITT (in this topic) A voice unlock app/substrate add-on. My friend had the idea to unlock your iphone based on the marauder's map in harry potter. Hah. He said he would like the phone to only unlock if you say "i solemnly swear that I'm up to no good" However, I would take it a step further by having it recognize a string command that you could change in settings. In the case where you would record your own message (say less than 10 seconds long) and if its repeated clearly than your iphone will unlock. The only fallback I could think of is failed voice recognition (which I heard is common with the new voice command feature) So a passcode should also be available for multiple failures. If anyone could develop this idea or even suggest more for it, that'd be great.
