Raul, The character file is just a list of 256 ascii characters, together with the pronunciation of each one in speakup. You can change the way your synth pronounces any one of these 256. I have done this, because I wanted my accent to say "dollar" instead of "dollars" for the dollar sign, and I wanted it to say "underscore" instead of "lkine" when it sees an underline. To make these changes in pronunciation requires a re-writing of the whole character file each boot up. What I did, for instance, was to copy the character file from the /proc/speakup/accent directory into my home directory. Thgen I edited the new file, made the changes I mentioned, and saved it. Finally, in my rc.local file, I put a line in that copies my home directory character file onto the one in /proc/speakup... You can't edit a file in the /proc tree, so this seems to be the only way. I probably told you more than you wanted to know. Best, Larry
