I have uploaded a beta test version of brass - a Braille and speech server for Linux. Brass is a combination of a screen reader with speech output and a Braille terminal driver like brltty. You can use speech and Braille or just one of it.
Supported languages are English and German.
The code of brass is based on the brltty code. The idea of soft cursor routing by screen attributes is from sbl, the SuSE Braille driver.
