No -- "don't need to" would be -nISbe' while this one has -be'nIS "need to not... = must not".
Or to put it differently; it's not that you -nISbe' "don't need" to Hot "touch" them; it's that you -nIS "need" to Hotbe' "not touch" them.
The suffix -be' belongs to the class of rovers, because it can occur at various positions in the string of suffixes -- and it negates whatever is before it. So positioning -be' differently will usually give different meanings.
I admit the n is not real strong, but I can definitely hear it. I even had my son (who does not speak Klingon and could not see the spelling) repeat the audio and he included an n. I think if the n were said any more clearly, it would sound unnaturally emphasized. How would you spell what you do hear?
