I was having a discussion about the pronunciation of "Phi" this weekend and I was referred to the following webpages which have pronunciation guides for the greek alphabet:
http://www.cogsci.indiana.edu/farg/h...an/grkphon.htm
http://www.mathacademy.com/pr/prime/...reek/index.asp
http://www.ibiblio.org/koine/greek/l.../alphabet.html
According to these pages the letter "Phi" is pronounced "Fee" in Modern Greek. There are many different pronunciations of Greek words, but current academics believe that Modern Greek is the closest to New Testament Greek (but not identical).
I could not find anything that lends validity to the idea that the pronunciation is different when the Phi follows a vowel, or is the second letter without a third.
