How can the XO be made accessible to blind

Espeak works fine, the XO just did not have the correct sound system config 
installed because somebody forgot to enable OSS emulation in ALSA. 

I hope you did not waste a lot of time editing the code for Espeak to get 
around this bug, I hope you did not edit it to make it pipe out sound data to 
be plaved via another utility, as espeak does all that by itself much faster, 
direct to the sound card without pipes, once the OSS sound system it requires 
is fully emulated in ALSA and it can use the required /dev/dsp and related 
file devices that it requires.

I actualy files some bugs on this; Look for keyword 'espeak'.
