Latin pronunciation in EB

[Tiberius Gracchus]

Mini question. The ligurians say Ligurii( they pronounce the AE as II, while the words are obviusly ae, so the should pronounce AE as in AI...
Or of course my hearing is impared, and they say what they should, but i don't notice the destinction

Or it's because they speak ligurian and not latin ;-).
