This issue occurs if the version of Windows Vista is not one of the following:

• The U.S. English version
• The United Kingdom English version
• The French version
• The German version
• The Spanish version
• The Japanese version
• The Chinese Traditional version
• The Chinese Simplified version

Speech Recognition is available only in these versions of Windows Vista. However, because of the way in which the Speech Recognition feature is built into Windows Vista, this feature cannot be removed from versions of Windows Vista for which Speech Recognition is unavailable.
