"Can I have a sound file please? yi-Latn or yi-Hebr would be acceptable."

(Yes that's a nonsense request, but it's nonsense that is both easier to
avoid sending, and easier to ignore the nonsensical part of if you have
separate language and script codes).

No, hence my tactical use of the word "perhaps" :)
