Is it safe to talk over bluetooth?

Troubleshooting audio and recognition accuracy

No audio signal

If Dragon cannot hear you speak, try these steps to solve the problem.

Check the microphone mode

Make sure the microphone is turned on. The microphone button in the status window should be green ().

  • If the button is red (), the microphone is switched off. Click the button to turn on the microphone. If the microphone button doesn't turn green, your microphone may not be connected properly. Please read the section "Checking the microphone connection".
  • When the button is blue (), the microphone is in sleep mode. Say Wake Up to turn it on.

See the Microphone Modes topic for more information.

Check microphone connection

Make sure the microphone is properly connected to your computer. If you're not sure which microphone is selected, click the -Sign in the menu bar and select Manage Profiles. You should see your selected profile on the left and your selected microphone on the right under Audio Sources. Missing microphones come with one -Sign marked.

If your microphone is missing, do one of the following:

  • Select a different microphone from the Audio Sources list and click Load; if you haven't listed an alternative audio source, click the Characters in the Audio Sources section to add one to your profile. For more information, see Profiles and Audio Sources.
  • Unplug the microphone, then plug it back in. If you are using a USB microphone, make sure it is connected directly to the computer and not to a USB hub.
  • For bluetooth microphones go to System Preferences> bluetooth and make sure bluetooth is turned on for your computer and your mic is plugged in.

Check microphone settings

If your microphone doesn't show up as missing, look for problems with the microphone itself.

Go to System Preferences> Audio and click the Input tab. Speak into the microphone. The input volume bar should respond to your voice. If it doesn't respond, there is a problem with your microphone.

  • Check if your microphone has a mute switch. If so, make sure it is turned off.
  • If you're using a bluetooth microphone, make sure it's turned on and charged.
  • If your microphone can be turned off, try restarting it.
  • Try your microphone on a different computer or device.

Important: If you change the input volume slider while in System Preferences, perform the microphone setup again the next time you start Dragon.

Restart

Restart Dragon.

  1. Click on that -Sign in the menu bar and select Exit Dragon.
  2. Go to the Applications folder and double-click Dragon.

You can also try restarting your computer.

Bad audio quality

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

While dictating, watch the input volume control in the status window. If it seems either too high or too low, try the following steps to resolve the problem.

Check the microphone orientation

Check that the microphone is oriented correctly and has not moved from the original position that you set in the Check Microphone utility. For more information on this topic, see Positioning the microphone.

Recalibrate the microphone

To make sure the microphone is properly calibrated for your voice and environment, have to Perform the Microphone Setup procedure for each profile and audio source.

If your input volume is too high or too low, you can always go through the "Microphone setup" process again by clicking on the -Click the symbol in the menu bar and select Improve detection> Microphone setting.

Reduce background noise

You should always try to reduce background noise for the best detection accuracy. Many microphones have noise-canceling capabilities that filter out background noise, but it's still good to keep background noise constant.

Listen to your audio

If the above steps didn't solve the problem, dictate some text into a document. Highlight the text and say Play Selection. If you hear gaps in the audio or frequency interference such as crackling noises, the microphone may be the source of the interference.

  • If your microphone needs to be connected to the computer, check the connection. Unplug the microphone, then plug it back in. If you are using a USB microphone, make sure it is connected directly to the computer and not to a USB hub.
  • If you're using a bluetooth microphone, make sure it's turned on and charged.
  • Try your microphone on a different computer or device if possible.
  • Try a different microphone. Perform the "Microphone Setup" procedure when connecting a new microphone.

Bad recognition accuracy

If your audio quality is good but Dragon doesn't understand your language, try these steps.

Check profile

If you have multiple profiles on the computer, make sure the correct profile is open.

  • Click on that -Sign in the menu bar and make sure that your profile has a check mark next to the name.
  • If another profile is highlighted, select your profile from the Recently used profiles list. If you don't see your profile, click Manage Profiles and select the profile in the Profiles section.

Language training

The more Dragon hears you speak, the better it will understand you. Speech training helps Dragon learn your speech patterns, intonations, and accents.

  • To start your language training, click on the Sign in the menu bar and select Improve Recognition> Speech Training.

For more information, see Language Training.

Train vocabulary

You can practice your vocabulary to teach Dragon how to use language. Dragon reads one or more text files of your choice to analyze which words you use and when and how often you use them.

  • To start practicing the vocabulary, click the Character in the menu bar and select Improve Recognition> Vocabulary Training.

See the topic Training vocabulary for more information.

If you have trouble recognizing a particular word, use Vocabulary Edit to train Dragon how to pronounce specific words.
