The Voice Tracker™ has no audio output.

  1. Check that there is power to the unit. The green LEDs should be lit, and track the talker as he moves around. If the LEDs track, the Voice Tracker™ is probably OK
  2. Check that your PC has selected the Voice Tracker™ as the recording device. In most cases, this is the problem. You can select the recording microphone as follows:
    For Windows 7, right click on the speaker icon in the lower right corner of the screen. Select recording devices. Highlight the correct Voice Tracker. Click “set default”

    1. For the Voice Tracker™ I, select the sound card.
    2. For the Voice Tracker™ I USB, select VXI USB 7.02.
    3. For the Voice Tracker™ II USB, select “Headset Mic Voice Tracker™ II”
    4. For the Voice Tracker™ II analog, select the sound card.
  3. For Windows XP, go to Control Panel (category view). Click on Sounds Speech and Audio Devices. Click on Sounds and Audio Devices. Select the audio tab. In the Sound Recording box select the appropriate Voice Tracker™ (as above)
  4. For the Voice Tracker™ I USB and the Voice Tracker™ II USB, be sure that the sound card is selected for sound playback.

The Voice Tracker™ I or II analog audio output is too low.

For Voice Tracker™ I:

Increase the “boost” in the PC or Mac.
In Windows 7:

  1. Right click on the speaker ICON on the lower right of the screen.
  2. Click the Recording Devices tab, highlight the Soundcard, and then click Properties.
  3. Select the “levels” tab
  4. Two “sliders” should appear. Set the “boost slider to ~40db and the other slider in the middle of the range. Adjust as necessary if the sound is too loud or too low.

Apply the settings

For Voice Tracker™ II (USB audio output):
Be sure the switch in the back is in the “line” position. Repower the Voice Tracker is you change switch positions.

If output level still too low, use the analog audio output connected to the soundcard and add boost as described above for the Voice Tracker I.

For Voice Tracker™ II analog output:
See instructions for Voice Tracker I.

The Voice Tracker™ II USB audio is too high

Set the output level switch to the mic level position. Repower the mic if you change switch positions

Warbling noise in audio output

Computers sometimes have a feature that tries to enhance low level audio. This “feature” can cause a warbling sound and noise when the audio recorded from Voice Tracker microphones is played back. It’s best to turn that feature off. For example, in Windows 10, go to “sound control panel” then go to the playback tab. Highlight the speaker output that has been defaulted. Go to properties. Go to “advanced” and make sure the box next to “Enable audio enhancements” is unchecked.

There is an “underwater sound superimposed” on the audio.

In addition to the spatial filtering provided by the beamforming of the microphone array, the Voice Trackers have a background noise subtraction algorithm, which filters out stationary noise (like fan noise and air ducts). If that noise is too loud, the background noise subtraction algorithm can cause artifact (the underwater sound). If you are experiencing this, move the Voice Tracker™ away from the source of the stationary noise. You should be able to do this and still pick up the talker because of the Voice Tracker’s long-range.

There is a Hum in the audio.

A hum might be caused by a ground loop through the wall power connection. This can be tested by running the PC on battery if you can. If there is a ground loop hum, isolate the power connection. You can do this with a product like the Hum-X

There is feedback through the PCs speakers.

If Windows is not set up correctly, the output from the microphone will play through the PC speakers. This is sometimes confused with acoustic echo.

To eliminate this:

For Windows XP.
See: here

For Windows 7

  1. Right click on the speaker ICON on the lower right of the screen.
  2. Click the Recording Devices tab, highlight the Voice Tracker™ Microphone, and then click Properties.
  3. On the Listen tab uncheck the option “Listen to this device”.
  4. Apply the settings.

The Voice Tracker™ II has insufficient acoustic echo cancellation.

Check to be sure that the sound playback level is set around the middle of the range. Control the output of the loudspeaker through its volume control, not the PC volume control. If you are using a preamp, be sure it is not nonlinear.

Also, check to be sure the Voice Tracker™ II is selected as the computer’s recording device. Some computers have built-in microphones, and if it is selected instead of the Voice Tracker™ II, there will be no AEC capability.

Can two Voice Tracker™s be used together to provide increased group coverage?

Two Voice Tracker™ Is can be combined using a simple 3.5mm Y or a mixer.

Two Voice Tracker™ IIs can also be combined, but if you are using the acoustic echo cancellation feature, you must provide loud speaker reference samples to both units.

Noise in the analog audio output of the Voice Tracker™ II

The Voice Tracker™ II should be powered by an external USB wall power supply (like our part 202) when used in the analog mode. PC provided USB power sometimes adds noise.

Voice Tracker II USB audio output not recognized by PC or Mac

Most often, this occurs when a USB extender is used. Try a different extender, or use the analog output of the Voice Tracker II connected into the soundcard or to a USB adapter like part 102A.

The other possibility is that the USB cable that came with the Voice Tracker II is defective. Try another USB cable.

Dragon NaturallySpeaking reports volume too low when Voice Tracker II is attached

When you add the Voice Tracker™ II as your dictation source for Dragon NaturallySpeaking, you must inform Dragon that you have a new microphone. You do this in the profile tab on the upper right-hand corner of the Dragon bar. Click on the profile tab. Select “mange dictation sources”. Choose the Voice Tracker II. You may need to do some training.
