Hands-Free Control provides a continuous listening service on your device to activate voice functions, even while asleep. When you speak the keyword “Siri”, Siri will be activated without pressing any buttons and then wait for further voice input.
Normally you have to press and hold the home button for several seconds to activate these voice functions, but now with this app these features are completely hands-free! Just speak the keyword! The service also works with headphones and bluetooth headsets.
Selecting your keyword, sensitivity adjustment to the keyword, settings regarding battery efficiency, and more are provided in the Settings app inside “Hands-Free Control.” An SBSettings toggle is also provided for quickly and easily switching the service on or off.
Because Hands-Free Control runs continuously in the background noticeable battery usage is to be expected while enabled
