I'm assuming Quo = Kwo? :3

It's hard to express how things are pronounced without writing everything phonetically.

I'm assuming the Qu in Miquo'te is like that in spanish or french (quelle blague!) rather than in english (quotation = Kwo-tay-shun). That may or may not be true, but I suspect it is. I'm usually quite good at pronunciation thanks to studying four languages (two, english and french to fluency) and linguistics where we had to write out words using the phonetic alphabet and studied the differences between accents. ' is usually a breath sound or break (except in some languages that vary intonation already and in complicated ways - such as english or chinese esp.). Since the race names are coming originally from Japanese, Japanese has fairly consistent intonation...which is usually an accent issue for native english speakers, since is rather hard for us to NOT vary intonation based on word placement/phonetics.


Example --
Mizuno Ami -- should technically be pronounced, without break and with same intonation on each syllable, as 'me-zu-no-ah-me', but you will find most english speakers say 'me-ZU-no (breath) AH-me'.

Taking common language conventions,

Roegadyn - roh-gay-din (assuming here that 'a' is long. If was short a, would be roh-ga-din. Roh-gay-din sounds more natural to me though and there's more precedence for a long 'a' in a middle syllable than a short 'a'.)
Hyur - hy-yur or hyur, depends on whether you make the word two syllables or one. Hyu is not a true sound in english so we may more naturally say 'hy-yur' and 'hy-yur-an' rather than hyur and hyur-an
Lalafel - la-la-fell (important NOT to intonate on 2nd syllable which will be natural to most english speakers. it's la-la-fel, not la-LA-fel)
Elezen - ay-lay-zen or eh-leh-zen, depending on whether or not you choose a long or short 'e' sound. Or you could even vary it - 'eh-lay-zen' - and since most elezen wording favors french pronunciations, I tend to favor 'ay-leh-zen' as if there was an accent aigu on the first e.

There will be some variation depending on whether you favor english-style intonation or japanese.
