Using Microsoft Edge WebView2 to display the content of the personalization and help window

Starting with the 2021.3 release, Dragon Medical One will use Microsoft Edge WebView2 to display richer content with improved usability in the Dragon Medical One personalization and help window. To support this improvement, you must deploy the Microsoft Edge WebView2 component to machines that host Dragon Medical One. Failing to do so will not impact the core functionality of Dragon Medical One but will potentially impact end users interacting with content displayed in the personalization and help window. To deploy Microsoft Edge WebView2 to machines hosting Dragon Medical One, install the Microsoft Edge WebView2 Evergreen Standalone component; for more information, see Webview2 - Microsoft Edge Developer.

Microsoft .NET Framework version

Starting with the 2021 release series, Dragon Medical One requires Microsoft .NET Framework 4.7.2 (or higher). Machines that do not have this version installed will not be able to start Dragon Medical One. The Dragon Medical One MSI installer will verify that .NET Framework 4.7.2 is installed on the machine prior to installation and abort if the correct version of the .NET Framework is not installed. Please make sure that your environment is updated.

Compatibility with applications based on the Java SDK

This release includes a change to the Java SDK that causes applications that integrate previous releases of the Java SDK to fail working with Dragon Medical One 2021.3 and higher. Previous releases of Dragon Medical One will not work with applications created with the new version of Java SDK. To deploy Dragon Medical One 2021.3 to your user base, you must integrate the Java SDK 2021.3 release into your application.


Improvements for end users

Section 508 compliance

Dragon Medical One is now Section 508 compliant: It introduces support for screen readers and allows end users to interact with the UI elements via keyboard only.

Keyboard navigation

End users are now able to navigate within the Options, Manage Step-by-step Commands and Manage Auto-texts dialog boxes via the keyboard only (without using the mouse); they can use Tab, Shift-Tab and the arrow keys to navigate between panes and UI elements within the panes.

Configuring hotkeys

End users are now able to configure hotkeys (for Dragon Medical One actions, step-by-step commands or microphone buttons) via the keyboard only by interacting with a button that allows them to enter the combination of keys they want to assign. After a user has assigned a hotkey, the focus is automatically moved back to the dialog box. For more information, see the end user help.

Screen readers

End users are now able to use screen readers to receive narrated feedback for the DragonBar and additional user interface elements in Dragon Medical One dialog boxes.

Windows voice commands

Dragon Medical One introduces new voice commands which enable users to simulate pressing keys and initiate actions without using the keyboard. The following commands are now available:

Solved issues


Application support


Known issues

Grundig device button support

When the Grundig virtual server device drivers are deployed to a virtual server environment and you encounter issues with device support, install the latest version of the Grundig device drivers.

Wake word

When deploying Dragon Medical One to virtual environments without installing the Nuance virtual extensions, the application will transition the recording state from standby mode to microphone off when a user reconnects to a previously used virtual server session. To resume with standby mode, start recording manually via the DragonBar, hotkeys or microphone buttons.

Hotkeys in virtual environments

As part of the accessibility compliance enhancements introduced in the 2021.2 release, Dragon Medical One enables end users to configure hotkeys and step-by-step commands via the keyboard by pressing an icon that allows them to enter the combination of keys they want to assign. However, in some cases, if another application is also listening for global hotkeys, Dragon Medical One might not receive the combination of keys correctly.

For example, the Citrix Workspace client (formerly known as Citrix Receiver) sometimes intercepts keyboard shortcuts and prevents Dragon Medical One from receiving them. The following list of keyboard shortcuts is not exhaustive:

Note: The existing hotkeys defined in Dragon Medical One are not affected and will work as expected. This problem only occurs when a hotkey is created or modified. This known issue will be addressed in a future release.


Use Dragon Medical One 2021.1.1 to modify or create hotkeys.

Best-effort support

If your environment does not meet the minimum requirements outlined, Nuance's ability to assist may be limited. This means that most functionality questions continue to be addressed, but if a bug is suspected or you are running into an issue that requires a technical investigation beyond known issues and fixes, we will recommend that you upgrade to the latest supported version. The following products fall into this best-effort support framework (this list is not comprehensive):

Third-party environments

Support for third-party environments is only valid as long as they are supported by the corresponding vendor and might be subject to other restrictions. Please contact Nuance Technical Support for details. For more information, see the documentation delivered with the third-party product and supporting Nuance documentation.

When standard support by the vendor has stopped, Nuance will continue support if an issue is specific to the Nuance solution, within the limitations of the vendor’s standard end-of-life and Nuance's policy. This means that issues that are a combination of the vendor’s component and the Nuance solution cannot be supported.
