Release Notes for Dragon Medical SpeechKit 2020.3 (iOS edition)

New in version 2020.3

• The version numbering for Dragon Medical SpeechKit, Dragon Medical Embedded and Dragon Medical Server has changed to a <year.quarter> scheme. The current Dragon Medical SpeechKit version is 2020.3.
• Dragon Medical Virtual Assistant: The DMVA server now returns Natural Language Understanding (NLU) dialog results alongside DMVA dialog results. To enable your app to respond to NLU results, implement the nluResult method of the NUSAVirtualAssistantControllerDelegate. [FLOR-20555]
• Dragon Medical Virtual Assistant: You can now define which concepts DMVA will listen for during an intent. When you prompt the user for a dialog response, call [NUSAVirtualAssistantController sharedController] promptForConcepts: with an array of concepts in priority order. DMVA will listen for the concepts defined by the promptForConcepts call and ignore other concepts not in the array. [FLOR-14886]

Solved issues in version 2020.3

• Dragon Medical Virtual Assistant: When your integration calls promptForFreeText or promptForChoice followed by stopDialog, there is no longer a significant delay before the dialog is aborted. [FLOR-15165]
• Dragon Medical Virtual Assistant: When your integration calls promptForFreeText or promptForChoice while another dialog is active, the new dialog is no longer unexpectedly cancelled. [FLOR-18756]

For more information, see "Setting up Dragon Medical SpeechKit" in the Dragon Medical SpeechKit iOS edition help. [DNB-8963, DNB-10129]

System requirements*

*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.

*Preliminary date; might change in future release notes.
