[tlhIngan Hol] The pronunciation of {Q}

In the tkd it says: "{Q} This is like nothing particularly noteworthy in English. It is an overdone Klingon {q}. It is identical to {q} except that it is very guttural and raspy and strongly articulated, somewhat like a blend of Klingon {q} and {H}". On the other hand, it is my impression that whenever I hear the word {Qo'noS} I actually hear "Kronos"; my problem being that I hear an "r" being spoken, which according the tkd shouldn't be there. Is there something here I am missing ? qunnoq
