Whistleblower system

Language packages for Windows Server

If you are deploying a whistleblowing system on your infrastructure (on-premises), you should ensure that the German and English language packs are installed on the Windows server.

The language packages provide text-to-speech (TTS) functionality that is used for the voice output of the captcha on the whistleblowing system.

Windows servers normally have at least the English language pack pre-installed.

If the German language pack is not installed, the English language output is also used on the German page.

Installation via Windows settings

1. Open the Settings on the Windows server.
2. Navigate to Time & Language.
3. Click on Add language. (Depending on the Windows Server version, you can add only the speech package directly under Language)
4. Select German (Germany) and English (USA) from the list.
5. Make sure that the Text-to-Speech option is activated.
6. Restart the application (stop and start in IIS Manager)
7. Check if the correct language is used for the TTS output of the captcha <domain>/CmWb/SecurityQuery. If it is not used, try to restart the complete server.

Installation via PowerShell

Alternatively, you can also install the speech packages using the following Powershell commands.

The Powershell must be started as Administrator!

Add-WindowsCapability -Online -Name Language.Speech~~~de-DE~0.0.1.0 -ErrorAction Stop
Add-WindowsCapability -Online -Name Language.Speech~~~en-US~0.0.1.0 -ErrorAction Stop

With older versions of Windows servers, this command may not be available. As an alternative, you could try the following commands:

dism /online /add-capability /capabilityname:Language.Speech~~~de-DE~0.0.1.0
dism /online /add-capability /capabilityname:Language.Speech~~~en-US~0.0.1.0
