What do other computer users say about sapisvr?

I was hit by this at the same time as a dozen other malware (something took down my firewall). It kept attempting to connect to the internet and run a Microsoft installer, in addition to taking almost 20MB of RAM when it boots.
this syware activates when ever you open a n microsoft program
I know that it was using 98% of my space because I had accidentally clicked on the wrong item in the dropdown file menu. That turned on the voice recognition tool bar. My computer had slowed to a crawl but when I canceled the voice recognition the speed returned to normal.
i think it activates self writing program when trying to write in WORD, passwords in internet etc.
I've disabled the speech recognition features in "Services" and the sapisvr.exe continues to launch 6-8X per day. I'm convinced the sapisvr.exe is removed from my computer and some malware continues to disguise itself and rewrites in several different recycler directories and other directories, e.g. prefetch, my programs, my documents. I have relentlessly tried to get rid of this it a nusance and a resource hog! Microsoft needs to step up and remedy this very vulnerable feature of XP
