What's new in version 2026.3 (5.6 R1)
The
NUSA_OnlineHelpURLproperty is deprecated. Dragon Medical SpeechKit no longer supports opening partner-supplied help URLs in the personalization and help window. [1647396]You can now use Nuance PowerMic and other supported button devices with Microsoft Edge browser on Windows. To use the device, install Nuance PowerMic Web Extension from Chrome Web Store. To install the extension, set Edge to allow extensions from Chrome Web Store.
Solved issues in version 2026.3 (5.6 R1)
The LED on Nuance PowerMic devices now correctly turns on when recording starts and turns off when recording stops. [2891815]
The slide switch on Philips SpeechMike devices now starts and stops recording as expected. You no longer need to slide the switch in and out of the Record position to toggle recording. [2703603]
SpeechKit no longer throws a TypeError when there's an
SVGAnimatedEnumerationobject on the page. [2637230]SpeechKit no longer adds a line break when it encounters a
labelelement within acontenteditablecontainer. [2645756]
Important information
- This release is only available in the Nuance cloud.
- CKEditor edit controls are no longer supported.
- For the personalization and help window to work on Firefox browsers, users must disable the Enhanced Tracking Protection feature. See: https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop
- Web browsers on mobile operating systems aren't supported.
- Dragon Medical SpeechKit (Browser edition) requires HTTPS with an SSL/TLS certificate bound to the web server.
- Dragon Medical SpeechKit 2026.3 (Browser edition) is compatible with Dragon Medical Server 2024, 2025, and 2026.
- Dragon Medical Server 2026.3 is compatible with client versions 2024, 2025, and 2026.
- Filtering auto-texts (defining filters to deactivate auto-texts selectively) is deprecated and no longer works.
- Don't change or hide Browser edition GUI elements. Changing or hiding these elements risks the stability and compatibility of the product. Nuance can't provide support for such integrations.
- You can't use web browser debugging consoles or debugging proxies (for example, Fiddler) with speech recognition. The performance impact incurred by such infrastructure leads to unreliable speech recognition.
- Corrections made by transcriptionists aren't used for author profile adaptation.
Supported edit controls
- HTML
<input>and<textarea>controls. <div>elements that have the HTML5contenteditableattribute set totrue.
Cursor position in a content-editable div
When you place the focus in a content-editable div (for example, by pressing the tab key or saying navigation commands), Dragon Medical SpeechKit doesn't interfere with the browser's default handling of setting the selection. Exception: When the div is focused for the first time, the cursor is placed at the end of the text.
The browser default can vary but the cursor is often placed at the start of the control rather than the end. To override the browser's default handling and place the text cursor at the end of the text, do the following:
- In the
NUSA_configurefunction, setNUSA_contentEditableDefaultSelection = false;
Note
You can say a text selection voice command and immediately move the focus away from the content-editable div (before Dragon Medical SpeechKit processes the command and selects the text). When you move the focus back to the div, the text is selected; the text cursor isn't placed at the end of the div.
Known issues
- In Google Chrome and Mozilla Firefox the page must be refreshed if the microphone is unplugged and plugged in again. [DNB-4123, DNB-18532]
- Nuance PowerMic in Citrix and VMware environments (Nuance-hosted systems only): When opening a speech-enabled page, there can be a delay before microphone buttons are available, from a few seconds up to half a minute depending on the network connection. This only occurs in Citrix and VMware environments; it does not occur when the user opens the page in a local browser. [CAVE-6198]
- Transcriptionists' last used audio position for a document is not reset when authors modify the audio. [DNB-49647]
Infrastructure
Infrastructure no longer supported
- Dragon Medical SpeechKit and Dragon Medical Embedded 2026 applications don't work with version 2023.4 servers.
- Version 2023.4 client applications don't work with version 2026 servers.
Infrastructure changes planned for the next release
- Dragon Medical SpeechKit and Dragon Medical Embedded 2027 and higher won't work with version 2024 servers.

End of life: third party environments
Support for third party environments is only valid as long as the corresponding vendor supports them. Support might be subject to other restrictions. 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 stops, Nuance continues 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 support means that issues that are a combination of the vendor’s component and the Nuance solution can't be supported.
Release channels
Dragon Medical SpeechKit (Browser edition) is provided on the following release channels: Beta, Mainline, and Delayed. You can configure these three channels for your integration. Rather than changing your integration to test different versions, you only need to switch your test installations to Beta.
Beta channel
The Beta channel is the version in development. Use this channel to verify that your application works with the upcoming version of Dragon Medical SpeechKit (Browser edition).

Delayed channel
The Delayed channel is one version behind the Mainline channel. This channel updates when a new major version of the Browser SDK is available. Use this channel to downgrade one version from the Mainline channel. If critical issues that affect your integration occur on the Mainline channel, report them to Nuance technical support so they can resolve the issues for the next Mainline release.

Remarks
- Version-specific paths (for example,
/3.3) were deprecated with the introduction of the release channel concept and are no longer available. - For speech recognition, each localized Browser SDK instance connects to its respective localized Dragon Medical Server production environment.
- The release channels provide different versions of the Browser SDK scripts. All three release channels for a given region connect to the same Dragon Medical Server production environment for that region.
- Nuance decides which channel to use for Browser SDK deployment, including skipping the beta channel and deploying directly to mainline. Nuance reserves the right to evaluate on a case-by-case basis whether a beta channel deployment is necessary.
- Nuance provides the beta version on the Beta channel on an "as-is" basis and doesn't guarantee its functionality. Don't use the beta version in production. Nuance isn't liable for damages arising out of or in connection with the use of the beta version.
- Nuance has no obligation to perform fixes to the beta version and might immediately and without notice change or remove the beta version or any part of it for any reason. Nuance might change, fix bugs or vulnerabilities in, remove features from, add features to, or otherwise improve or modify the beta versions of SDKs before removing their beta designation.
