Bu Ses Hakkında
This is a short two-second voice clip of Romano Prodi introducing himself in Italian with the line Buona sera, sono Romano Prodi, meaning good evening, I am Romano Prodi. The delivery feels formal and deadpan, which makes the simple greeting sound unexpectedly funny and grand when you hear it out of context as a standalone announcement.
