Supported microphones

Audio works for all microphones listed. Support for button controls is listed below:

* To enable Nuance PowerMic controls, install the Nuance PowerMic Citrix Extension/PowerMic RDS Extension/PowerMic VMware Client Extension.

** To enable button controls for third-party devices, install the corresponding redistributable packages.

*** To enable button controls for these devices, configure USB device splitting.

Remarks

• Important: Olympus DirectRec devices are no longer supported; the available Olympus drivers are end-of-life.
• For more information on virtualized environments, see the Docs & Guidelines folder of the Nuance virtual extensions package on the Nuance Healthcare Development Platform.
• Nuance Citrix/RDS/VMware Audio Extension and Nuance PowerMic Citrix/RDS/VMware Extension:

The extensions do not need to be installed on the server/virtual desktop; the required server binaries are already included in the application folder.

Make sure you uninstall the corresponding server/virtual desktop component setup if it is no longer used by other products.

• Nuance RDS Audio Extension and Nuance PowerMic RDS Client Extension: UDP transport must be disabled on Remote Desktop Protocol (RDP) 8.1 clients and on RDP 10 clients. RDP 8.1 is preinstalled on Windows 8.1 and installed by Microsoft Update on Windows 7 and 8. RDP 10 is preinstalled on Windows 10.

To disable UDP transport, add the following registry keys and value to the Remote Desktop Client, then restart the PC:

Keys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Terminal Server Client

DWORD Value:

DisableUDPTransport = 1

• The 64-bit version of the Nuance Citrix Client Audio Extension for Linux is now available.
• VMware Horizon View 7.3: RTAV with device splitting is recommended if Nuance audio channels cannot be used.
• To enable microphone button support for Philips and Grundig devices, contact your device vendor for drivers that support your virtualized environment; deploy them on the server/virtual desktop where your application is hosted and on the client PC.
• Microsoft RDS: When the Grundig drivers are not installed on both RDS server and client endpoint, the application using a Grundig device might become unresponsive when reconnecting to a session.
• Philips SpeechMike on Linux thin clients in a Citrix environment: Session reconnect might not work. Solution: Make sure SpeechMike firmware version 2.54 or higher is installed.

System requirements - edit controls*

*End-of-life: 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.

Dragon Medical SpeechKit product life cycle

Nuance provides support throughout the life cycle of one version and point release. Please note that Nuance will not perform problem analysis after the scheduled start of restricted maintenance. Dragon Medical Server versions released over three months after the dates stated here will not work with these client editions.
