Dragon NaturallyClear USB—User’s Guide Supplement

T

he Dragon NaturallyClear™ USB is the best way to ensure high-

quality sound input for speech-recognition applications, even on
laptop and other computers with inherently noisy internal
environments.

Accurate speech recognition depends on high-quality audio input. The
USB System includes built-in sound card elements for converting
speech into digital form and accepts all high-quality headset
microphones compatible with Dragon NaturallySpeaking®. Digitized
speech is fed directly into the speech-recognition program through a
Universal Serial Bus (USB) connection. This solution guarantees high­quality audio input, regardless of the quality of the computer's sound
card or built-in sound system.

System Requirements

The USB System works with any USB-compliant Windows® 98, Windows
2000, or Windows Millennium computer with an av ailable USB port. It
will work with any continuous speech-recognition program from Dragon
Systems

For system requirements of a specific speech-recognition program, see
the documentation for that program.

, including Dragon NaturallySpeaking 5.

Installing the Microphone

device.

jack on the USB pod.

2 Insert the black plug on the headset micr ophone into the headset jack on the

USB pod.

3 Plug the USB connector for the pod into an available USB port on your

After you complete the Add New Hardware Wizard, you may receive an
error message stating that Windows has not installed a driver for the device.
Despite this message, the installation has been successful.

You can use the USB System with multiple USB ports, but the first time
you plug the microphone into a new USB port you must repeat steps 3
and 4 above to install the appropriate device drivers.

O

Attention

While the USB protocol allows the “hot-swapping” of USB devices, we
recommend that you shut down Windows before unplugging the
device to avoid potential problems.

Testing the Microphone and Establishing User files

When you install the USB System for use with Dragon
NaturallySpeaking or another Dragon Systems speech product, you
need to establish new user files and recalibrate the product’s audio
settings.

1 Start Dragon NaturallySpeaking.
2 Create a new user with the New User Wizard.
3 Select “USB Microphone” as your Dictation Source in the New User

Wizard.

4 Select “USB Audio Device” on the Choose your sound system dialog box.

If “USB Audio Device” is not listed as a selection, if you receive an
error message, or if the sound quality is evaluated as unacceptable for
speech recognition, see the following troubleshooting section.

5 Continue through the New User Wizard and then complete General

Tr a i n i n g .

Note After creating user files for the USB Audio Device, user files

created for other audio devices may not work. To correct the
problem, run the Audio Setup Wizard again for those user files.

Troubleshooting

System locks up when you plug in the USB connector

On a computer system that does not follow proper USB conventions,
there is a chance that the system may lock up when you plug in the
device. If this occurs on your system, contact Dragon Systems
Technical Support.

USB Audio Device is not listed as a selection in the Audio Setup Wizard

1 Open the Windows Device Manager (From the Start menu, click on

Settings, then click Control Panel. Double-click the System icon and
click on the Device Manager tab.) In Windows 2000, click the
Hardware tab, and then click Device Manager.

2 Verify that the USB Audio Device is listed and enabled (not marked by a

yellow circle with exclamation mark) in the Sound, video and game
controllers section.

3 Verify that the USB Composite device is listed and enabled (not marked by

a yellow circle with exclamation mark) in the Universal serial bus
controller section.

4 Close the Device Manager and Open Multimedia/Audio properties (In the

Control Panel, double-click the Multimedia icon and click on the Audio
tab.) In Windows 2000, double-click the Sounds and Multimedia icon.

5 Verify that the USB Audio Device is listed in the Sound Recording

drop-down menu.

If the devices are not listed and enabled as stated above, you may need
to enable USB configuration in your system BIOS. (Some
configurations disable the USB ports by default.) If necessary, remove
the USB Audio Device and/or USB Composite Device and then try to
reinstall the microphone. If installation fails again, contact Dragon
Systems Technical Support.

Microphone does not appear to be picking up sound

Check that the microphone is properly connected to the USB pod and that
the USB pod is properly connected to the USB port on your computer.
