The computer that always listens for voice commands used to be the stuff of science fiction. Google has already initiated Ok Google as a code word to listen for further commands on Android devices, and now iPhone users have the jailbreak tweak OkSiri. Normally, Siri requires a long press of the home button to start listening. With OkSiri installed, an Activator gesture tells Siri to be ready for a custom code word.
Once installed, the first step is to define the code word that will invoke the main Siri screen. By default, this word is set to Ok Siri under Settings -> OkSiri. To change the work or phrase, enter the text and then activate and deactivate Siri the traditional way. With the code word configured, the next procedure requires assigning an Activator gesture to OkSiri. This makes it possible to switch the listening mode on or off.
