Re: [orca-list] How are you increasing the eSpeak rate beyond what speech-dispatcher permits?

["B. Henry" <burt1iband gmail com>]

I may be wrong, but I think NVDA speeds things up by a factor of 4, although it seems more than that.
I'll have to test, but 20% with the boost sounds faster than 100%, or at least the same. I seem to remember 
using around 20% with boost anyway, and 100% 
with out it was just barely fast enough for me at the time.
That would imply a boost factor of 5 or even 6, but I think I heard it was four. 
This could be atributed to the different ranges in the bottom and top register. 
Let me think for  a sec..., (smell the smoke coming out my ears?),
OK, a factor of five might make more sense if my memories of my subjective comparison are correct, i.e. 20% 
is close to 20wpm, 18 actually in the bottom 
half of a default configuration with a   90word per min difference between 0 and 50%. 
Add 80 to 18 and 98 times the boost factor 5 gives you something like 490 wpm, notably faster than 390, and 
enough faster to make a difference to most 
folks  if top end is set to 450, and that would fit my impressions, or at least my memory of them.
Cheers for fears,
