found temporary fix for 2.6.10 and 2.6.11 software speech problem

[Janina Sajka]

Thanks, David. How can I say it? Very, ahem, nice? <grin>

I shall probably need to muck around with the settings. Your minus five
and vie numbers do seem to have improved things, but there's still way
to much lag for me when typing chars.

Question: Do you notice more lag on capital letters than on lower case?
I get significantly more lag on caps, perhaps more than twice as long.

If Linux can't solve your computing problem, you need a different problem.
