I believe (since we don't know for sure--I also teach philosophy, so what do we REALLY know anyway?;-) that the classical Latin pronunciation would be rendered "deh NOwo," with a slight buzzing sound on the 'w.' What we do know about pronunciation is based on poetry (thanks to rhyme and meter) and the tradition of the language having been taught continuously for thousands of years. BTW, I have always asserted to my students that Latin is not a dead language--it is, rather, immortal! For a host of good reasons to study the language, you may peruse the following website:
