Simple, but wrong.
The syllables are misrepresented.
Kokyu ho: koh-cue-ho
To be completely accurate, the "u" sound in Japanese is made without rounding the lips. Of course, my Japanese is terrible, but most Americans won't know the difference!
To be even more accurate, the "ko" is a short, clipped sound, not as long in duration as the usual English "oh". Meanwhile, the "ho" is a longer sound, roughly two beats' worth of the first "ko". So the "ko" is a little shorter than normal English "oh", and the "ho" a little longer than the normal English "oh". The "u" of "kyu", incidentally, is also two beats long. Just a smidgen longer than, say, the letter "Q".
