  • For a Bluetooth microphone, go toSystem Preferences>Bluetoothand make sure that Bluetooth is turned on for your computer and that your microphone is connected.

    2. ClickSound.
    3. The Sound Preference Pane appears.
    4. Click theInputtab.
    5. Make sure the microphone appears in the listed devices.

    1. Make sure the microphone you configured with Dragon is selected, then speak into the microphone.

You should see theInput levelindicator respond to the sound of your voice. If it does not respond, there is a problem with your microphone.

    • If your microphone can be turned off, try restarting it.

Poor audio quality

If Dragon is able to hear your voice, but the recognition seems poor, you may have a problem with the quality of your audio input.

While dictating, watch the sound input bar in the Status Window. If it seems very high or low, try these steps to solve the problem.

Check your microphone placement

Ensure the microphone is positioned properly and has not moved away from where you originally positioned it when you ran Microphone Setup. For more information, seeMicrophone placement.

Recalibrate your microphone

To make sure your microphone is properly calibrated for your voice and environment, youmustgo throughMicrophone Setupfor every profile and every audio source you use.

If your audio input level is too high or low, you can go through Microphone Setup again at any time by clicking theDragon menuicon in the menu bar and selectingImprove Recognition>Microphone Setup…

Reduce background noise

For best recognition, you should always try to minimize background noise. Many microphones have noise canceling capabilities, which filter out background noise, but it’s still a good idea to keep background noise consistent.

Listen to your audio

If the above steps do not solve the problem, try dictating some text into a document, thenselect the textand sayPlay the selection.If you hear gaps in the audio, or interference such as crackling sounds, your microphone may be the source of the problem.

  • If your microphone needs to be plugged into your computer, check the connection. Try unplugging the microphone and plugging it in again. If you are using a USB microphone, make sure it is plugged directly into your computer and not a USB hub.
  • If you are using a Bluetooth microphone, make sure it is adequately charged.

  • If a different profile is checked, select your profile from theRecent Profileslist. If you don’t see your profile, clickManage Profiles…and select from the Profiles pane.
