This 128-bits can also be represented in, let's say base-50K, by using five words chosen from a 50,000 word dictionary. If you also make "this", "This" and "THIS" separate, then you can get away with a 17K word dictionary. Depending on the language, if you use roots and then vary morphology based number, tense, etc., then the number of root words (and the choice you have in making them simple) can be reduced. Such "pass phrases" can be easier to remember, transcribe, etc. (Also you will get random, humorous, offensive, etc., phrases...)
