RoboBraille is an e-mail service which can convert digital text documents into either Braille or audio files. It is quick and easy to use RoboBraille. You simply send an e-mail with an attached text document to RoboBraille. Shortly after, you will receive the document back from RoboBraille in the specified format - an audio file, for example.
