The S Voice™ Drive feature of the Samsung Galaxy S4 is designed to be used whilst in the car. Open up the app and a new homepage appears with larger icons that are much easier to hit. There are fantastic voice control features that allow you to listen to texts read out loud, then reply by voice, access the navigation, find a destination just by asking and of course make calls.
For use while driving of course! When you're at the wheel you don't want to have to touch your smartphone or take your eyes off the road... but you do of course want to use your phone, read texts and so on. S Voice™ on the Samsung Galaxy S4 lets you check your messages without having to look at the phone's screen as the text can be read out loud. Replying is as easy as talking back to the S4. Receiving a call? Just answer and get talking. How about if you get lost? No more fiddling with the touchscreen on your smartphone, the S4 lets you tell it where you want to go and it'll get you on your way.
The S Voice™ Drive app is activated as soon as you attach the Samsung Galaxy S4 to a car Bluetooth. Once it's connected and the app's fired up, learn the easy commands and you're good to go.
