A quick look at the rather exotic Assembly dialect sources of PROVOX tells me that there is no obvious text to phoneme translation algorithm but just tables on how to pronounce special chars or to spell out things char by char when the user requests that. There are tables for a large number of special chars which seem to vary across hardware speech synth brands but PROVOX seems to expect that the speech synth indeed has local CPU power and firmware to convert English text to speech inself,
Yes, that's what I have found in the mean time as well. I also installed "JAWS" (another screen reader, not open-source but freeware) and with JAWS I am able to get actual human phrases being sent to my linux loopback from a VirtualBox-ed FreeDOS install. There is a lot of control codes as well, but that was to be expected of course. I guess that the trouble I have with PROVOX is simply my inability to use it. Whatever I try to do, it just "beeps" at me, probably holding text to be said in some buffer that I am unable to release because I miss some expected key combination or so.
Anyway, I will probably fiddle with this in the coming days - at least to understand how this all works under the hood.
