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

This is part of Windows XP's voice recognition software. It's not malware and not a security risk. Just make a habit of noticing if the microphone icon on your toolbar is on or not.
   
Sometimes my computer slows to a crawl. Task Manager reports sapisvr.exe hogging 99% of my resources. Have never used speech recognition so logical conclusion is that it's malware

I activated my voice recognition and this thing keeps opening up and will not go away. I can still use the system but it keeps acking for a disk to be put in the drive \device\harddisk6\dr8

System file that's part of speech. Don't delete. It's no spyware: it's digitally signed

I opened a pdf file that I had saved to a microsoft docx. When I tried to move it to another folder (keeping organized) it would not move and a pop-up window said it was open in sapisvr. The original pdf moved with no problem. I had just moved another file and it was then that I looked it up to find this webpage. I turned off my voice recognition and was able to move it. Definitely related to docx files.

I started using Speech Recognition and the problem started. I just exited from Speech Recognition and the problem has gone

Best practices for resolving sapisvr issues

A clean and tidy computer is the key requirement for avoiding problems with sapisvr. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
