Possible Speech Recognition Problems

If no sound is entered after testing the system (see Troubleshooting Speech Systems), try the following suggestions.

The SR engine may be bad. Try switching to another engine. See Changing the SR engine. If another engine is working properly, reinstall the specific engine from the original source. If no engine is working properly, reinstall the SAPI component from the original source or CD.
The microphone level is too low. On the Speech Recognition tab, select Configure Microphone. Follow the directions in the subsequent Microphone Wizard to set the input level.
The microphone is muted. Some microphone have an external control for muting. Make sure the mute is turned off.
Microphones are also controlled through software. Look in either Sounds and Multimedia or Multimedia properties item in the Control Panel, under the Audio tab and Sound Recording section. Additional information is available through the associated Help files.
It is possible the microphone connections are not properly made. Check the documentation for the Microphones hardware for additional information. This may also include making certain the sound card for the computer is also properly seated, installed and the correct drivers are available.
