The BlueAnt S4 allows drivers to make and receive calls on the road using only their voice. To activate the S4, drivers just need to 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, 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".
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 AndroidTM 2.x smartphone, your incoming messages will be read out automatically as they come in.
The S4 also features integrated A2DP streaming audio functionality, for listening to music or podcasts and hearing turn-by-turn direction information from a GPS application on the phone.
Users with Android devices can further enhance their BlueAnt S4 by installing the BlueAnt S4 Android application. The application provides text message readout directly into the headset and includes help and support for your S4.
The S4 also features embedded audio help that talks you through the setup and pairing process, and if you can't remember the voice commands you can ask the S4 "What Can I Say?" and it will tell you the available options.
