[orca-list] setting speech rate higher than 100 percent

[Bill Dengler <billkd314159 gmail com>]

Hello,
I realize that this is more of a speech dispatcher thing, but how do I 
get espeak to talk faster than 100 percent without using the 
espeak_generic module and causing extra delay?
Running the following at a shell produces the desired rate :
espeak -s 500 "This is a test of espeak at the shell."
