Dorabora’s favorite word
I went to the Forvo website to check on the pronunciation of ‘Usonia’ (as a proposed new name for the U.S.), but found that they did not have this word covered. They do, however, have the adjective form ‘Usonian’ covered, albeit by only one instance, given by a contributor identified as ‘dorabora’. Her profile gives her favorite word as a certain Russian word, that you can listen to here: https://forvo.com/user/dorabora/favorite-pronunciations/
It so happens that there is an Esperanto connection here: She studied phonetics under John C. Wells.
