Spanish, Vietnamese, and Cantonese TTS on ChromeOS Version 119+ Issue

Jan 17, 2024

Due to a recent change in ChromeOS, Chromebooks running version 119 or later will no longer have voice packs for text-to-speech installed by default for the following languages: Spanish, Vietnamese, and Cantonese. The consequence of this change is that students will not be able to activate text-to-speech for these languages in the Secure Browser on those Chromebooks. CAI is actively working with Google and unfortunately, there does not appear to be a quick fix that can be implemented systematically for all devices. As we continue to investigate options, there are two recommendations for students who need text-to-speech for these languages during the upcoming test administrations:

  • Arrange for students to use another device for testing or a Chromebook that is still running a version of ChromeOS before 119.
  • Install the voice pack manually using the following steps:
  1. Enable the option for the ‘floating accessibility toolbar’ in the ChromeOS Management Console. This must be done by the system administrator.
  2. Open the Secure Browser on the device(s) that need a voice pack.
  3. Click on the new floating toolbar in the right-hand corner of the screen and choose settings.
  4. Choose “Text to Speech” and then “Text to Speech Voice Settings.”
  5. Scroll down and select “More Languages” from the Preferred Voice Options.
  6. Select “Chrome OS Built-in Text-to-Speech Extensions” from the speech engine options.
  7. Install the voice pack for the desired language (For Spanish, install the United States voice pack).
  8. Disable the option for the floating accessibility menu in the ChromeOS Management Console again. This is required.

Note: Mandarin TTS and Russian TTS are not supported on ChromeOS. Students needing to take the SEED Survey with Mandarin or Russian TTS must use a different OS.
