I see lots of passive studies of sperm whale click "language", usually focused on fingerprinting to identify groups and individuals. There's application of deep learning, and all sorts of advanced analysis. However, I haven't found any examples of scientists actively producing their own clicks and trying to elicit responses from whales. It seems to me that successful interactions would push our understanding of the clicks forwards much faster with a bit of a debug/test cycle.
Have studies like that ever been done? If so, can I please have links/references to the papers? Thanks!!
