Does that number refer to all, most, or some ? By experiment, I've made some progress on this: SPEAKUP PARAMETERS The parameters key_echo and no_interrupt are boolean: 0 or 1. The important silent parameter is a bitmap, but its bits are not well documented; it is known that 7 means silent and 4 restores speech. The punc_some, punc_most and punc_all parameters are strings containing lists of punctuation characters. The reading_punc parameter can then be set to 0, 1, 2 or 3 in order to select which punctuation characters are pronounced when reading (for example with Keypad-8), and the punc_level parameter can be set likewise to select which punctuation characters are pronounced when the computer writes them to the screen. 1 selects punc_some, 2 selects punc_most, 3 selects punc_all, and 0 supresses pronounciation of any punctuation. For reading prose, you'll probably prefer 1, and for a programming languange probably 3. The speakup parameter synth is a string, which must exist as a subdirectory of the speakup parameter directory. The parameter synth_direct is not a parameter, it is a direct input to the synthesiser; use this if your application needs to say something. The synth_direct input bypasses speakup, and works even if the silent parameter is set to 7. It seems to use punc_some, regardless of the settings of punc_level or reading_punc. SYNTH PARAMETERS The punct and tone parameters may be set to 0, 1 or 2. freq seems to control the expressiveness of the voice (the amount by which its frequency varies during speech), whereas pitch seems to adjust between a low voice and a high voice. The important vol, pitch, freq and rate parameters are 0 to 9, default 5. See: http://search.cpan.org/perldoc?Speech::Speakup I haven't discovered any effect that the synth parameter "punct" might have. For example, it doesn't seem to change the punctuation level when using synth_direct, nor when reading_punc and punc_level are both set to zero.
