Compass for blind people

I have to develop a compass for blind people.
A compass to speak, saying the angle from the north.
I have already found the sensor to the sensor (the CMPS09 - Tilt
Compensated Compass Module) that I can connect via the serial port to
BeagleBoard. Now I have to convert the information coming from the
serial to voice messages. Does anyone have an idea or knows a
software / library / documentation to facilitate the work?
Thanks

hi,

speech maybe is overdone for a single value. check the auditory
thermometer. this way, you could even get away with a simple piezo
beeper on a gpio for audio output (well, you can get away without the
beagleboard but hey ..). i'm sure the cyclical nature of the values to
be represented makes for some interesting challenge.

this is nice for example, using 4 different kind of continous signatures
for each of the compass points and just crossfade.
