How would I go about translating this into Dovahzul?

I'm working on a Skyrim mod, and I wantt to translate the title "Voiceless" into Dovahzul--and I'd like it translated twice-over, the first time with the meaning of Voice as in Voice of Power, Thu'um, and the second time with the meaning of Voice as in Mortal Voice/Speech, so Zul. Essentially, I'm missing the negative suffix. There's no translation for a word meaning "the absence of" in Dovahzul.
