The hardware might be available but that doesn't mean it will work with
the linux kernel.

The RC systems where the litetalk comes from still sells litetalk
serial and I think usb synthesizers and the prices for these the last
time I checked was about $190.00 less than I paid for my original
synthesizer something like $350.00 many years ago. Hospitals use
hardware speech synthesizers to direct patients when certain
diagnostic tests and treatments get done.

Subject: Re: Help with serial synths in 4.X kernels
Well, first of all, I didn't mean to say you shouldn't use a serial
hardware synth. However,IMO, you would be wise to consider
contingency plans. If your livelihood depends on that serial synth,
you'd be wise to begin examining your alternatives.
Also, I can't promise to debug the kernel code. When I said check the
syslog, I meant for you to check the syslog. If I can find the time
to take a look at it, I certainly will but I can't promise that. I
suspect that what's happening is that when speakup tries to "steal"
the serial port, the return value is no longer just null. When I last
traced back the functions that speakup was calling to steal the
serial port, it was bullstuff. Speakup called a function that did
nothing -- which isn't the fault of the speakup developers. I suspect
that those functions now do something -- probably not what we want
but something.
It has probably been a year since I last posted a rant on this list
about the linux kernel developers. As I write this, I find myself
getting all worked up about it again. The one good thing about Trump
running for President is that now I have someone I find more arrogant
and irritating than the linux kernel development team.

time my ubuntu machines download a new kernel, generate a new
patched kernel
package. I never got around to it though. I was using a sed command to
comment out the line that caused serial synths to not work so that
automation was possible. Part of the problem here is that I have
kind of
given up on serial synths myself. I have been depending more and
more on the
combination of a braille display and software speech. It seems to
me that
using a hardware speech synth is going against the grain these days.
As Karen and others have pointed out, we all have our own personal
speech preferences. In my case, I have multiple reasons for wanting
serial speech to work. I find it easier to hear and understand for
one thing. There are some bugs in the DECtalk Express module which
might be easily fixed, but the last unpatched kernel I know of that
actually worked was 2.6.32 which is no longer supported. Anyway, as
requested, here is the dmesg output. I don't see anything helpful. I
did the following:
