Change Details

Some languages (e.g. Welsh, `cy`) [[ https://cloud.google.com/text-to-speech/docs/voices | are not a supported ]] `lang` parameter by certain Phonos engines — currently, Phonos will fail to render any audio when an unsupported language is passed. In these cases, we should try [[ https://www.mediawiki.org/wiki/Manual:Language#Fallback_languages | to fallback to another "parent" language ]]. E.g. ``` <phonos text="llandudno" ipa="/ɬanˈdɨdnoː/" lang="cy" /> ``` will return an error message and render no audio, whereas falling back to ``` <phonos text="llandudno" ipa="/ɬanˈdɨdnoː/" lang="en" /> ``` returns an audio rendering. Further examples at https://en.wikipedia.beta.wmflabs.org/wiki/Phonos == Acceptance criteria == - When provided with an unsupported language, Phonos will show an error message (and not use the [[ https://www.mediawiki.org/wiki/Manual:Language#Fallback_languages | already established ]] language fallback path). - The error message will, if possible, suggest alternative (supported) language codes. - When provided with a supported language, Phonos will send the request unchanged. - The user-provided language code will be normalized as appropriate (e.g. if `PT_BR` is given and `pt-BR` is supported then no error will be shown).

We did think about [[ https://www.mediawiki.org/wiki/Manual:Language#Fallback_languages | falling back to another "parent" language ]], but decided against that.
