Summary: If you have speech recognition always enabled it can cause your computer to "go nuts" because of the different sounds it interprets as actual words.
It's a really weird thing to watch - it's almost like your computer has suddenly become possessed. But the question holds a clue: sapisvr.exe. Chances are, though, the computer is really only doing what you're telling it. Literally. • Sapisvr.exe is Microsoft's Speech Recognition engine. When enabled, it listens to what's coming in on the microphone and attempts to interpret what it hears as words, then enters keystrokes to "type in" those words it heard. That's nice, in principle, but if it's always enabled it can cause exactly the odd behavior you describe. You make a noise (just about any noise can cause it to think it's heard a word), and keystrokes get entered. Or ambient noise is enough to cause it to try to recognize speech. Normally this feature should be disabled, but apparently some PC manufacturers or others enable it by default. "... it listens to what's coming in on the microphone,
and attempts to interpret what it hears as words, and then enters keystrokes to
'type in' those words ..."
To disable:
And if you're wondering why this could be happening if you don't have a microphone, look again. Many laptops in particular have built-in microphones, and I'm lead to believe that some other computers may as well. Related:

Your article came up on Google and I wanted to thank you for having the directions for removing that microphone thing. Mine was running every time I started up Outlook and made everything run slow. Just wanted to say THANKS again for having this posted online. :))
Posted by: TheTess at July 23, 2006 2:34 PMMy PC sometimes always reboot for no reason, for an example, i was using Window Media Player while checking mail, it went reboot for no reason and restarted like it was nothing serious error happen. Then there's a time when i watch movie by using Window Media Player, it went reboot like just now,then i tried using the cyberlink software to watch again but it happened again when i was watching the movie(the pc reboot after sometime,not right after the movie played).There is another example,i opened too much IEXPLORER windows and it went reboot again.i can't play game even some game that require low performance like yahoo's ZUMA.Another problem is after i play some high requirement game for sometimes my pc went reboot for sure.Is this because of memory things and graphic card.I'm using Windows XP service pack 2 and i don't have a graphic card, my RAM is a single 512MB DDR II RAM.

Posted by: Apostolos at February 15, 2007 2:57 PMYou helped me so much.

Leo,
Thank you. What a strange experience it is to watch one's computer start spitting out text in whatever textbox is active.
Leave it to Microsoft to install a friendly feature like this, and bury the disable way down inside a control applet. Come to think of it, there's no disable button--just a remove.
And even after Removing, according to Task Manager, sapisvr.exe is still running, soaking up 44K of RAM and another 28K of swap disk. I'll reboot to see if the bugger dissapears.
Another tidbit: according to TaskMan, sapisvr.exe has passed over 27 million bytes since boot, 4 days ago, and written over 19Mbytes. What can it be doing all that data?
Thanks again.
Posted by: Kurt W.G. Matthies at April 30, 2007 11:43 AMMy comp first used to suddenly reboot for no reason...whether i am playing a game or i am watching a movie or working....but now, it most of the times does not even starts...there are options shown such as
1) start in SAFE MODE.
2) Last known configeration.

Posted by: Neel at February 4, 2008 7:06 AMWhen I am in Mozilla or IE all of a sudden the text in the browser window will start jumping all around. I have to shut my computer down for it to stop. When I open any document everything is also jumping around. You can hear a noise coming from the computer when this happens as well. I use a wireless mouse. If you grab the slider on the right of the window it will flicker also and return you to the top of the page automaticaly. Very frustrating
