As of December 12, 2023 the text-to-speech function for Chromebooks in kioskmode was altered by Google to no longer include standard language packs. This means most languages and voices (except for English and French) in text-to-speech are no longer supported for any kiosk applications.
We will be looking into alternative solutions, but in the meanwhile we recommend one of two options:
1. Using Immersive reader instead (which includes a text-to-speech function).
2. Rolling back ChromeOS to 118* (an earlier stable version).
If you choose to go with option number two, this guide demonstrates how to configure your managed Chromebook environment to roll out an earlier version of ChromeOS that still includes the standard language packs. This will allow you to continue using Digiexam as a kiosk application with the standard languages available for text to speech.
Step 1: Enter your Google Admin Workspace environment
Navigate to https://admin.google.com/. Here you should choose "Devices" and then select the "Chrome" section of your navigation menu to the left.
Step 2: Change settings for Chromebook devices
Select "Settings" from the navigation menu to the left. After this choose "Device Settings" from the tab menu in the section to the right.
After doing so you can navigate to the "Device Update Settings" section for Chromebook devices in your organization.
Then choose "Auto-update settings" from this section.
Step 3: Allow updates & roll back the operating system for devices
Make sure that "allow updates" is selected from the auto-update settings.
Change the target version to version 118* as this is the version where text-to-speech where all standard language packs are available.
Lastly, alter the roll back settings for the target version so that it will roll back the operating system.
This will push out the version you selected.
Save these settings to complete the roll out of the operating system to all devices.
