About this guide
Who should read this guide
This guide is written for any administrator in an organization who manages either the Citrix
server or the supporting software on client computers that allows them to connect to the
server.
Dragon products included here
This guide is for customers who purchase either Dragon Professional Group or Dragon Legal
Group. Because deploying Dragon with Citrix is the same for both of these Dragon products,
for simplicity, this guide uses the terms "Dragon Group" and "Dragon" to reference any of the
Dragon group products.
Information covered in this guide
Inside this guide are details about hardware, software, and network requirements for deploying Dragon Group within a network made up of client computers that connect to a Citrix
server to access published applications or published desktops.
For those who need information on administering the features available in the Dragon software, please see the product's administrator guide.

Dragon Group Citrix Administrator Guide
Choosing a Citrix deployment solution for Dragon Group
You can deploy Dragon Group with Citrix in one of the following ways:
Option Usage Limitations
Install Dragon Group as a
published application on
Citrix XenApp server
Install Dragon Group on a
Citrix XenDesktop server
Publish Dragon and use it to dictate into other published applications that are located on the
same XenApp server.
Install Dragon on a virtual
desktop published with
XenDesktop and use it to dictate
into applications that are
installed on the same published
desktop.
NOTE: If you choose this deployment option, you will need to
install a software utility on each
of your client computers, so be
sure to coordinate with your
Desktop Administrator.
In this implementation, users
can't use Dragon to dictate into
applications installed on a published desktop or any installed
locally on the client machine.
In this implementation, users
can't use Dragon to dictate into
applications installed on a separate published desktop or published individually with XenApp.
They also can't dictate into any
applications installed locally on
the client machine.
Additional considerations when deploying Dragon Group on a Citrix server
Using Dragon Group in a Citrix environment has an impact on your network resources. Consider the following before proceeding with this type of deployment.
Higher loads on
your Citrix server
Higher bandwidth
use
8
Moving the dictation processing to your server will increase CPU usage
and processor demand.
Users with analog microphones need to transfer high-resolution audio
data to the server. In addition, anytime a user has an analog microphone turned on, they use 1.3 Mbps of network bandwidth. Bandwidth
limitations can make Dragon difficult to use.
(Note that USB microphones use less than 1.3 Mbps of network bandwidth.)
Overview of dictation flows with XenDesktop and XenApp
When Dragon is installed on a Citrix server, it appears to function as if it were installed on the
client machine, but behind the scenes, there's more happening.
A user initiates the process by launching Dragon remotely from a client computer, and then
launching a destination application, which is the application he or she wants to dictate into.
There are some important requirements for where both applications must be located:
When Dragon is published in XenApp, the destination application must be installed on the
same XenApp server.
When Dragon is installed on a published desktop in XenDesktop, the destination application
must be installed on the same published desktop.
Once both applications are running, the user dictates into a microphone connected to the client computer that has been pre-configured to route audio into Dragon on the Citrix server.
The steps for configuring the microphone depend on whether you're using XenApp or
XenDesktop, and are detailed later in this guide.
Dragon receives the audio and transcribes the dictation into text, which it transmits to the destination application.
The text displayed on the client machine reflects all changes.
