Kanzi Understands Spoken Language

View this video on YouTube

In this clip, Primatologist Sue Savage-Rumbaugh holds head-phones to Kanzi's ears, playing a recording of a word that corresponds to an item on Kanzi's Lexigram board.

Sue cannot hear the words that are being read to Kanzi, so she checks an ordered set of cards to confirm that Kanzi has pressed the right button.

In this exercise, Sue holds a welder's mask to her face so that she can't give any obvious nonverbal clues as to what objects she's referring.

Kanzi seems to demonstrate an understanding of a wide range of nouns, verbs, and their relationships sufficient to carry out requests given in new phrases he may not have heard before.
