Possible speech recognition problems

If no sound is detected after testing the system (see Troubleshooting Speech Systems), consider the following:
  1. The microphone is muted. Some microphones have an external control for muting. Make sure the mute is turned off.
  2. The microphone input level is set too low. On the Speech Recognition tab, select Configure Microphone. Follow the directions in the subsequent Microphone Wizard to set the input level.
  3. The microphone may not be selected as the current input device. On the Speech Recognition tab, click Audio Input to make sure that the microphone is selected.
  4. It is possible that the microphone connections are not properly secured. Make sure the microphone wires are intact and unbroken. The connections to the computer may be loose; unplug the wires and reconnect them making sure they fit snugly. See Set Up a Microphone for additional connection information.
  5. Check the documentation for the microphone's hardware for information specific to the manufacturer. This may include making certain the sound card for the computer is also properly seated, installed and that the correct drivers are available.
  6. The SR engine may be corrupted. To test for corruption, switch to another engine if you have one. See Changing the SR engine. If the other 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.
