- Use Your Voice to Make and Receive Calls - 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 Hear Your Messages on the Go - The S4 integrates with Vlingo SafeReader so that you can hear incoming text messages read aloud. Once the Vlingo SafeReader application is installed on your BlackBerry or Android 2.x smartphone, your incoming messages will be read out automatically as they come in. Voice Access to the World - The S4 integrates with Microsoft BING-411 to provide a handsfree gateway to a world of information. Just by saying the words you can hear stock quotes, movie times, directions, weather forecasts, sports results, news and traffic updates. A2DP Streaming - The S4 features integrated A2DP streaming audio functionality, so you can listen to music or podcasts and hear turn-by-turn direction information from a GPS application on your phone.
