How it works

TalkBack makes it possible for you to use a finger to “explore” what’s on the screen.  Whenever you come across some element that can be acted on or a block of text that can be read for you, TalkBack springs into action. The screen reader service will read all text (including notifications and time). In the case of a web address, all the characters will be read out so that the user can get it right. For any elements that represent some form of action, TalkBack says out loud exactly what you’ve touched. If you want to follow through with the action, you can just easily double tap.The entire app is very well thought out. If you’re using it for the first time, you get a tutorial that covers the entire setup and lets you know how to set various options. You can activate TalkBack by navigating to Settings>accessibility on your handset. The setting galore contains things such as options for the speech volume, reading out caller ID, using different pitch, etc. You can turn vibrations on and off, as well as control the volume of any form of audio (including music) so that you can always hear TalkBack clearly when it’s got something to tell you.TalkBack is one of those outstanding assist technologies that Google is increasingly including in Android. It’s a great tool if you find that you need it. The audible feedback cues are very reliable. If you know someone who has trouble seeing very well, consider setting up this piece of technology and get them the help they need on their on their device.
