My hunch (and it isn't really more than that) is that a discrete system
would probably work better in these circumstances.
However, if neither is successful perhaps a more restricted vocabulary set
would be helpful. In the very worse case perhaps she could use the system as
a voice operated keyboard. This would require a vocabulary of only 60 or so
'words' (obviously using alpha, bravo etc for letter names) which would
hugely improve the chances of correct recognition. It wouldn't be quick
(maybe 8-10 wpm) but may compare favourably with her typing speed (obviously
I don't know this student but many keyguard users struggle down in the 2-3
wpm zone). Using a cut-down copy the dictation vocabulary may not yield much
improvement since the common words (that you need to boost your overall
speed) tend to be short and monosyllabic and thereby hard to recognise
accurately. The efficiency of the system could be improved by using a
Prediction system to speed up getting longer words (check compatibility
though, a keystroke pushed from a VI system may not be 'seen' by the
Prediction package.)
I think you and student may have to experiment for some time to arrive at an
optimal solution for her.
Hope this helps.
