Suggestions of messages to pre-synthesize:

• "wikispeech-error-loading-audio-title": "Could not load audio"
• "wikispeech-error-loading-audio-message": "This can be caused by bad internet connection or ..."
• "wikispeech-error-nonexisting-page-title": "Non existing page" (suggested in T254864)
• "wikispeech-error-nonexisting-page-message": "Can't play non existing page" (suggested in T254864)

• "wikispeech-error-nonexisting-page-title": "Non existing page" (suggested in T254864)
• "wikispeech-error-nonexisting-page-message": "Can't play non existing page" (suggested in T254864)

It might be worth looking into where the message comes from and see if we can reuse it. It looks differently depending on wiki, see e.g. https://www.mediawiki.org/w/index.php?title=Apa and https://sv.wikipedia.org/w/index.php?title=Finnsej.

I see, so perhaps we instead want?:

• "noarticletext"
• "noarticletext-nopermission"
• "newarticletext"
