Paywall, but I think the orca research is much much further than the sperm whale one (this is the first time I’ve heard about the sperm whale research).
They’ve been recording sounds and orca actions near Vancouver Island for 50 years already. The audio decoding is already done, they can group the individual orcas into family groups based on pronunciation alone. Last time I checked they were working on deciphering the decades old log books. Because without any connection to the actions orcas take in response to their sounds we will never know what the sounds mean.

This should be the website of the research station: https://orcalab.org/research/
on scholar.google.com you should be able to find papers that use their data.
