One more interview from CES. I sat down with BlueAnt to hear about their True hands-free bluetooth device. To activate the S4, all you have to do is say the hands-free trigger phrase "BlueAnt Speak to Me" and the S4 will be ready for your voice commands.
To make a call, just say "Phone Commands" and the S4 will activate your phone's voice dialing feature. When the phone rings you won't need to take your eyes off the road to know who is calling because the S4 will read out the caller's name or number and ask you if you want to take the call. All you have to do is say "Answer" or "Ignore".
