From a little script I wrote to "say" code on a text-to-speech announcer. The symbol words are chosen to be single-syllable as much as possible. It can also restore text from the results. I may post the script sometime.

equate( " \t\r\n",
    qw(space tab return line) );

equate( '!@#$%^&*+:;',
    qw(bang at hash buck cent hat and star plus colon semi) );

equate( '<>()[]{}',
    qw(less more open close elbrack arbrack elbrace arbrace) );

equate( '-=_|',
    qw(dash is bar pipe) );

equate( '\\/~`\'",.?',
    qw(hack slash wave tick tock quote comma dot query) );

equate( '0123456789',
    qw(zero one two three four five six seven eight nine) );

equate( 'abcdefghijklmnopqrstuvwxyz',
    qw(ay bee see dee ee eff gee aitch eye
       jay kay ell em en oh pee cue ar
       ess tee yoo vee dub ecks why zed) );
