The mp3 converter function in Natural Reader is very handy. It allows you to be free from the computer, and an internet connection. You simply highlight the text you want to save as an mp3 file and click on the mp3 converter button. Next you designate where you want to save the file. That's it! You're done. :) Now you can listen to the text you selected anywhere you want... on a walk, in the car, while you make dinner.
