Let me guess, You're using Office XP or later.

This is part of speech and handwriting recog software.  It is also a toolbar option (Language) for the main tool bar at the bottom of your monitor. 

If you don't use this feature. just remove it.

Open Control Panel, go to ‘Add/Remove Programs’
Find Microsoft Office and click on the ‘Change/Remove’ button
Under ‘Features to install’ click on ‘Office Shared Features’
Click on ‘Alternative User Input’
Click Speech and select ‘Not available’ from the drop-down box.
Click Handwriting Recognition and select ‘Not available’ from the drop-down box.

Hope this helps.
