WD2002: Speech Recognition Inserts Text, Responds to Commands Without Microphone (279797)
The information in this article applies to:
This article was previously published under Q279797 SYMPTOMS
Even though you do not have a microphone physically installed on your computer, speech recognition may insert text into documents or respond to commands.
CAUSE
The microphone is on and speech recognition is enabled. When the Microphone button on the Language bar is enabled, speech is enabled. Any sound coming through the sound card via a Microsoft Office Assistant (for example, the Office Assistant is speaking), a compact disc, an external input device, or an internet radio, may be interpreted as speech. This behavior occurs even if a microphone is not physically installed on your computer.
RESOLUTION
To resolve this problem, turn off the microphone by clicking the Microphone on the Language bar or by pressing the Windows logo key+V shortcut keys.
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION
Any sound played through the sound card can be picked up and recognized by the Speech Application Programming Interface (SAPI) as information for speech to recognize. Therefore, Microsoft recommends that you turn off the microphone feature, not just the physical microphone, when you are not using speech recognition. And, you should not play music or run Microsoft Agents that make sounds when using speech recognition, or you may encounter erratic results, degraded system performance, and lower quality of speech recognition.
