How do you pronounce kyu?

Answer 1

恐竜 /kyou ryuu/ means dinasour.

kyou: first try to say ki and long oseparately, then speed up pronouncing them consecutively, to a level that the i part of ki would almost fade, and not be heard.

ryuu: same as kyou just fading of the isound here is slightly less and the second part is long usound instead of o.

Answer 2
