Sure, if you spell a V you must pronounce a V.
DEVRA is a variant of DEBORA/DEVORA(H), for some reason the O was dropped. So you have many different spellings of the name and each one has it's own right. The original name from the Hebrew bible is pronounced Dvo-rah with the stress on the second syllable. This is at least how it is pronounced in modern
Israel. The E (like in
Deborah or
Devorah) comes in because the quiet vowel after the V (it is called Shwa) was taken as a sounding vowel by the Greek and Latin translators. Take
GIDEON: In the Hebrew bible it is GID'ON, but the translators but in the E and in Latin it would be pronounced Gi-dee-on.
Confused? - Good.
