Does the iPhone have talking GPS?

Is it possible to use a verbal code word or a button combination for activating a function in an iPhone App?

• We are currently talking to a security and health care company who asked for an app which allows to activate some functions inside an app with a verbal code word or a button combination. Like that you are in danger and just push a button combination 3 times or for an old person, who is alone at home and collapsed on the floor and just shout out a verbal code word. After that some functions are called inside the App (like a kind of status update, GPS data should be sent) and the security company should be called and the employee of the company should have the possibility to listen whats happening there. Would this be possible with a usual iPhone or do we have to use a jailbreaked one?

• Answer:

  Unfortunately, apps don't have those privileges in iOS. the microphone is not always listening and thus a verbal command won't be interpreted unless the device is told to listen (same for other phones). Even then there is no way to launch an application without first unlocking the phone as the default voice control is limited to phone calls and ipod functions mostly. The same goes for a button sequence. The only way to get an app to do things is to either open it or send it a push notification, which isn't feasible for your purposes.
