I’ve never been able to find it there’s been much research in communicating with dolphins. Especially with all of the latest machine learning and translation research. It would be so cool if they could open source a data set of dolphins recordings with context. (Maybe sound and video) Does anyone have the sea world connections to make that happen?

I'm pretty sure that research to that effect is going on, even involving attempts at simple bi-directional communication with dolphins in the wild. It's just slow and hard - wild dolphins are nowhere near as easy or cheap to deal with as fancy mice in a cage.

  I thought that too but I can’t find anything. Maybe the two skill sets are just so different that no one ends up working on it. Marine biology and data science.

I saw a video on the long now channel today with dr. Laurance Doyle about dolphin communications and other species. Dolphins start at 30 minutes. He basically found that dolphins language follow the Zipf law and Shannon information theory. Baby dolphins also have a babbling periode like humans in the same timespan. It is interesting talk all the way through. Maybe you can contact him. https://youtu.be/H30NipTkA5s https://youtu.be/H30NipTkA5s https://simple.m.wikipedia.org/wiki/Zipf%27s_law https://simple.m.wikipedia.org/wiki/Zipf%27s_law

It is not easy, we have not yet cracked the code, plus will they even have the motivation or any interest to communicate with us? What we do know is that they produce a variety of signals, some very complex and their communication is super fast, which is another obstacle for possible "communication". For example, we cannot generate a burst pulse with our current technology, we can only record theirs and play it back. But many research groups are trying. We are starting Dolphin Chat citizen science project on Zooniverse in a month or so, to classify and prepare a large dataset of bottlenose dolphins' vocalizations for out deep learning model. You can check it out and even participate, it will definitely help to appreciate how complex their vocal repertoire is (and how "chatty" they are).

  What do you actually mean by 'we cannot generate a burst pulse with our current technology'? What is the obstacle?

    The obstacle is that we still do not fully understand nor are able to replicate their sonar, even the Navy that has been studying dolphins for decades still cannot duplicate biosonar (read more here: https://www.nationalgeographic.com/news/2019/5/140328-navy-dolphin-sea-lion-combat-ocean-animal-science/ https://www.nationalgeographic.com/news/2019/5/140328-navy-d...) The burst pulse is extremely complex, some can have 400 single clicks in one pulse (our ear cannot even hear these single pulses, they merge and for our human ear it sounds like a creaky door), and the pulse duration is like a few seconds. Each click is broadband (can go up to 100 kHz and beyond), it is frequency modulated with varied peak frequencies, center frequencies, RMS, some clicks can have 2 peaks, etc. It is super fast and super complex, we we cannot just generate one, only dolphin's sound producing mechanism can.

  Really cool. Do you have a link?
