Serbian Text to Speech

The automatic text to speech does not appear to be working for the Serbian content on my desktop (Chrome). It works fine on my Android phone.
Is this a known issue? Is it possible to fix?

It’s a known issue and unfortunately it’s not possible to fix it for now. Google doesn’t yet have support for that language for other sites, it works on Google Translate directly and Google TTS app. Hopefully we will be able to use it soon enough.
