Probably applies to the Doubletalk PC as well. I might also suggest putting in the params to change punctuation level (none/some/most/all in punc_level (0-3)); keyboard echo on/off (key_echo, 0 or 1); keyboard interrupt (where the keyboard will interrupt speech or not)... Also say_control (0 or 1)... Those are settings that work regardless of the synthesizer. Anyway, here's what i've found for the doubletalk LT (probably PC as well)--I'm sure Kirk will correct any errors: ffreq: 0-9 Voice: 0-7 pitch: 0-99 Rate: 0-9 Volume: 0-9 Tone: 0-2 -- Buddy Brannan, KB5ELV | From the pines down to the projects, Email: davros at ycardz.com | Life pushes up through the cracks.
