So, what is the correct way to pronounce Livia? The girl just before pronounced the v as a v in English, but here it sounds like w.
In Classical Latin, it is supposed to be pronounced as 'w'.
Or rather, think of it as a short u-sound inbetween vowels. The romans even treated u and v as the same letter, as it has the same sound.
As the others said, in classical latin it was a "w" sound, but in vulgar latin, it evolved into the "v" sound as we know it. So depends if you want to put on a late latin accent or a classical one
So, in a classical reconstruction, you pronounce v is w, but you pronounce it as in English in church or medieval Latin
