Decktalk hardware is analog. software Speech is not.
For me personally the frequency ranges used for software speech output,
along with many devices like some cell phones can do me physical harm.
recently I was helping someone try to find a dectalk USB, and one of my
associates builds a sort of USB box that uses the most current dectalk
software speech in modules form.
what they told me was that the dettalk 5, which is this software edition
sounds nothing like hardware dectalk, and is quite difficult to
understand.
I asked on list once why dectalk hardware like my reading edge does not
work in the graphical Linux environment, and was told because no one has
bothered.
If no one bothers to write graphical options for hardware speech, not
because it cannot be done, but because they choose the free stuff instead,
that says allot about Linux creativity speaking personally.

DECTalk hardware is by definition text-to speech technology, as it takes
marked up text, but can also take text without any markup, and it converts it
to audible speech. It in fact does exactly what a software speech synthesizer
does, but it does it over a cable instead of via a virtual cable, pipe or
library of functions. In fact, DECTalk once was a software speech synthesizer
that sounded almost exactly like the hardware, as it was most likely the same
software internal code of the hardware adapted to be able to use the hardware
found in a PC. In fact, if you can still find this old DECTalk software, as I
recall, it was able to take your text and create .wav files in much the same
way that newer software speech synthesizers can do now. I know that people
were making it sing, not by recording their hardware, but by making and
mixing .wav files produced by the software. And any .wav file can be
converted to mp3 using lame, which is one possible answer to the thread
starter's question.
