Citrix Virtual Apps and Desktops

Introduction

Citrix Virtual Apps and Desktops supports Nuance PowerMic and Philips SpeechMike dictation microphones for use within HDX sessions, enabling voice dictation and microphone control in published applications and virtual desktops.

These devices are commonly used in environments that rely on speech recognition workflows. In Citrix sessions, dictation microphones present as composite USB devices that expose audio and HID interfaces. Citrix HDX supports these devices by handling audio input through the HDX audio virtual channel while redirecting required device interfaces to the session to ensure application compatibility and button functionality.

This page describes supported scenarios and provides guidance for enabling Nuance PowerMic and Philips SpeechMike devices in Citrix Virtual Apps and Desktops environments.


Important — Third-Party Statement

Nuance PowerMic and Philips SpeechMike devices, along with associated speech recognition software, are third-party products. Citrix Virtual Apps and Desktops supports these devices at the virtualization and HDX transport layer only.

Citrix does not develop, certify, or provide support for third-party device drivers, firmware, speech recognition engines, or application-specific functionality. Device behavior such as transcription accuracy, button mappings, and application responsiveness is determined by the third-party software and underlying environmental conditions.

For issues related to device hardware, firmware, drivers, or speech-recognition application behavior, contact the respective device or application vendor. Customers should validate third-party compatibility and supported configurations directly with the vendor before deploying these devices in production Citrix environments.
