[tlhIngan Hol] do the filler words express the "asking hmm" too?

There are two types of "hmm". 1st type: What do you want to eat? hmm.. I'll have the qagh. 2nd type: So, what's it gonna be? hmm? will you eat the qagh? I think that we could say with certainty, that both {ghghgh} and {Hu'ma/Hu'mI/Hu} express the 1st type of terran "hmm". But do they express the 2nd type too? ~ Dana'an remain klingon
