[DECtalk] Question About Formant vs Natural Speech

[Karen Lewellen]

Personally, I would add that the screen reading program can also 
influence how a synthesizer voice sounds.
I have used the dectalk synthesizer of my reading edge for years, finding 
it sounds different, though be it slightly,  when the program in question 
is say vocal eyes, as   opposed to say business vision, or tiny talk.
  might say the same between use of say a dectalk express or internal card, 
and the edge as well.
Only speaking personally of course,   but I dare say a bit of human 
interpretation  might be factored in too.  comparative to those who can 
hear the difference between an mp3, and actual  quality musical playback.
