Having reviewed the various notes the Paul Dilley in the mailbase
archive, one striking difference I have noted is the way in which
simultaneous input & output can be handled.
The majority of current sound cards are not proper 'full-duplex'
where the card has 2 sets of circuitry (including Creative's Sound
Blaster range even though they offer a 'full-duplex driver'), one
to handle audio in, the other to handle audio out simultaneously, and
this was reflected by the fact that Paul listed scenarios where input
was handled by a sound card and output was cared for by a synthesiser
or second item of hardware.
Full-duplex cards are much more common now however (indeed the
Keystone product is built around this gear I understand), and our own
recent experiments with the Turtle Beach Tropez Plus which was
available via mail order (£170) has proved that when combining Dragon
Naturally Speaking and TextHelp, it did read back what was
recognised by the voice package. I should stress that it worked,
but not very well and so served to prove only that it was possible,
but we have yet to allocate more time to improving this and also
trial with other voice input packages. I anticipate that we will have
greater success with the discrete speech packages, but for now I
can't say positively either way.
This probably only serves to make the issues less clear, but I
thought it was worth mentioning!
