Yep Sleuth, Nelsons work seems to have morphed into the straw man that he is now translating the language. That is not his claim, only that there is strong indication of a language based on phonetic elements phonemes or words repeated by two or more speakers etc. He has assembled a phonetic alphabet for the phonemes but claims no understanding of what is being said. He says there is tonal inflections that correspond to human conversation when asking questions or making imperative statements. This is just expressing his insight on the sounds. I'm sure it rubs people the wrong way if BF is just an animal to them, but if BF does speak, it is obviously much more.
