Stanford Converter into Braille & E-Text Project
From: Stanford University

The Stanford Converter into Braille & E-Text (SCRIBE) is an online document
conversion system supporting the transformation of text and image-based file
types into different formats. Individuals upload files through a Web
interface and select from a variety of ouput options, including audio,
Braille, or e-text formats. The SCRIBE platform will convert text files into
alternate text file types as well as convert image-based files into text
formatted files. MP3 audio versions are created using the high-quality
NeoSpeech text-to-speech voices.
