I don't know if those are all correct. I'm from the
UK, and I say
Viola,
Clementine,
Adele,
Sophia,
Maria and
Irene the way you say is American.
I have definitely never heard
Sophia or
Maria pronounce with an "eye" sound in them, and I know a fair few Sophias and Marias.
Mariah, like
Mariah Carey, might be pronounced this way...
