speakup and vim problem with key echo

[Rynhardt Kruger]

Hi list,

When using vim on my archlinux system with speakup, I get a strange problem with key echo when I type text in insert 
mode. Instead of reading every character as I type, it sounds like it's reading the previous typed character two times 
before reading the current one. For instance, when I type hello, instead of speakup saying "h e l l o" I here "h hhe eel 
lll llo". 
Has any of you encountered this problem before? Is there an option in vim I can set to eliminate this problem? I guess 
it's because of highlighting or redrawing that vim does which is confusing speakup.

Take care,

Rynhardt
