Control Your Android Phone with Google Now and Voice Access

Google has released an app into Beta that allows you to control almost every aspect of your phone with just your voice. The app is called Voice Access. Once started, either by Voice or by tapping the icon in the notification tray, your screen will display numbers next to icons or buttons that you want to Press with your Voice. See screenshot:

Surprised as I was by this great feature, I was even more surprised that even the button on Widgets are also accessible by Voice. Navigation by voice is not limited to Number. You can also say things like Go Back, Go Home,Next, Swipe Left, Swipe Right, Scroll Down, or say Show All Commands to learn how to turn your volume up or down, turn on or off WIFI or Bluetooth. 

To use you must sign up for the beta here: https://g.co/voiceaccess and you will be linked to download the app.
