Hi @sezanzeb ! The voices available for read aloud depend heavily on your browser and operating system. Firefox does not come with any voices, and can only use voices available on the Operating System. On Linux devices, adding voices is a bit difficult; this page has more info: https://askubuntu.com/questions/953509/how-can-i-change-the-voice-used-by-firefox-reader-view-narrator-in-ubuntu .
Regardless we should display an error or fallback to festival when no voices are present on WebTTSEngine.
I can't reproduce this issue on Firefox Mobile + Android.
