[tlhIngan Hol] The pronunciation of {Q}

[mayqel qunenoS]

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 ?
