This article provides information on the compatibility between Citrix XenApp server and Dragon NaturallySpeaking dictation software of Nuance.
Nuance, the maker of Dragon NaturallySpeaking software stopped supporting XenApp because the program neighborhood client piece was removed from the Citrix ICA client (see Additional Resources section in this article for further details). Dragon NaturallySpeaking is not supported with versions later than 11.x client.
Nuance has officially stopped supporting the product in a Citrix environment because of the changes in the Citrix Online Plug-in 12.x and later versions. Nuance recommends to install Dragon NaturallySpeaking software directly on the client system instead of running it as a published application from a XenApp server (some users have reported success using the 12.3 Citrix Online Plug-in but it is not supported by Nuance).
Nuance released a newer product called Dragon Medical 360 Network Edition that can support the higher Citrix Receiver version 3.x. To continue using a Nuance product for digital dictation, call Nuance to discuss about pricing and features.
