Lose the old-fashioned belt-packs and use a modern translation app like LiveVoice. LiveVoice is affordable, effective, and easy. Plus, their new 3.0 interface should streamline workflow even more than before. Your Spanish (or whatever language) translator sits in your annex or translation booth, speaking into his laptop or phone on one channel. Your second-language listeners tune into a website on their own smartphones using their own earbuds. Easy! No equipment to charge or maintain. Learn more at https://livevoice.io/en.
