How to use the "Text-to-Speech" feature on your kindle keyboard?

1. First make sure the Text-to-Speech is enabled ( you will see sth like " Text-to-Speech: Enabled " on the right side of the image of the book on AMAZON website)  for the book you want to read. If not, you cannot continue. 
2. Press the five-way controller to navigate the book, then press the center of the controller to open it.
3. Press the "Text" key (marked with the letters "Aa"), then press the five-way controller to select the "turn on" after "Text-to-Speech". The kindle should start reading the text. You may change the volume by pressing the button which is on the same side of the power switch.
4. If you want to have more options such as   "Turn off" "Pause" , change the speech rate to "slower" "default" " faster" or change the speaking voice to "female" or "male" , press key "Aa" again.
5. Press the "Shift" key ( with an arrow  ) and the "Sym" key simultaneously to stop the Text-to-Speech reading. Press again to resume.
