Fair play Skeeter. I am unaware of Standard Pronunciation in American English ( not saying it doesn't exist). RP or Standard Pronunciation certainly does in English as I'm sure you're away. I'm not really certain as I'm really just re-hashing some stuff I did years ago in Linguistics. Seeing if I can still remember it. Not really a pedant,I just get bored at times and look around for answers to things that puzzle me. Hence the hunt for an answer to the Oral/Aural dilemma. I seem to remember that in Latin it would definitely be OWral as in "ouch" or 'Gaudete'.

Skeeter. What a ridiculous generalisation; given the many different regional accents that exist in both countries. As for 'owrally' being impossible?? I would imagine that the majority of people in English-speaking countries would have no problem at all in pronouncing it (whether you mean 'ow' as in 'ouch' or as in 'blow'). Either would present no difficulties at all that I can foresee.

Medphilips. The booklet may be free but contains one error already; "three' and "free" are not homophones as they both begin with different phonemes.I haven't got a phonemic alphabet font but the Greek one will suffice. 'th' is shown as /θ/ and 'f' as /φ/.
There can be no confusion whatsoever.
