I'm as or more cynical than the next guy - but it seems to me that being able to communicate with animals has high utility for humans. Partly from an emotional or companionship perspective as we've been doing with dogs for a long time, but maybe even on purely utilitarian grounds.
If we want to know something about what's going on in the ocean, or high on a mountain or in the sky or whatever - what if we can just ask some animals about it? What about for things that animals can naturally perceive that humans have trouble with - certain wavelengths of light or magnetic fields for example? How about being able to recruit animals to do specific tasks that they are better suited for? Seems like a win for us, and maybe a win for them as well.
Not sure what else, but history suggests that the more people have been able to communicate with each other, the better the outcomes. I assume this holds true more broadly as well.

I was just reading how fishing industry’s longlines have caught many dolphins and other bycatches. It would be great to be able to give them warnings, or even better, to ask them to keep other big animals away from the longlines.

I know this comment is totally innocent but it does kind of bum me out to be at a point in time where instead of addressing our impact on the environment directly, we're trying to make computers that can talk to dolphins so we can tell them to stay out of the way lol
9dev
Or, like, we could stop ravaging the oceans by industrial fishing, stop pretending magical technology will save the day, and try to limit our resource consumption to sustainable levels?
Humanity’s relationship with animals is so schizophrenic. On the one hand, let’s try to learn how to talk to cute dolphins and chat with them what it’s like to swim!, and on the other, well yeah that steak on my table may have once lead a subjective experience before it was slaughtered, and mass-farming it wrecks the ecosystem I depend on to live, but gosh it’s so tasty, I can’t give that up!

Dear Mr Dolphin, can you please tell the large sharks to not go that way?
- No, f... the sharks!

Or, you know, don’t fish at all so we don’t kill possibly trillions of sentient fish every year for no necessary reason whatsoever?
Side bonus, we also don’t kill the highly sentient and highly intelligent creatures you’re concerned about.

I am all for the Disney utopian fantasy of us living with animals.
However if universal communication was to be made. Don't you think that animals are going to be pretty pissed to discover what we have done with their kingdom?
"Hi Mr Dolphin, how's the sea today?" "Wet and a plastic bottle cap got lodged in my blowhole last night..."

There's an Apple TV+ series called Extrapolations with a plot of a dystopian future heavily affected by climate change. One of the plotlines involve humans successfully developing the technology to communicate with humpback whales.
So, the story involves an animal DNA archivist interacting with what's presented as the last living humpback whale, focusing on its isolation etc. It turns out the research lab's goal is to trick the whale by faking mating signals, aiming to get it to reveal information about whale history and culture. It's essentially data mining the animal.
Nifty3929
I'm not suggesting a Disney utopian fantasy. I'm just suggesting that in a very pragmatic way, we can ask them questions and get meaningful answers, or ask them to do things for us.
What's going on down the the sea over there? Would you mind pulling that thing from here to there?
Or whatever - I don't know what we'll figure out to do, but certainly something.
As far as them being mad at us, I doubt they will be, but I'd be interested to get their perspective - if they have one.
I do not believe we can expect anything resembling a human level of intelligence to be discovered.
lesuorac
I suspect Dolphins can tell people apart and will recognize you as not the guy that threw the bottle cap akin to all those stories about crows.
Certainly will be interesting to see how much we can bribe Dolphins to do once we have faster communication methods.

It's trendy to hate Google, and even more trendy to hate anything AI.
The cynicism on display here is little more than virtue signalling and/or upvote farming.
Sad to see such thoughtless behaviour has reached even this bastion of reason.
lotyrin
"virtue signalling" really is one of those words/turns of phrase that needs to be put on a high shelf.
Plenty of people genuinely dislike the concentration of economic and computing power that big tech represents. Them expressing this is not "virtue signaling", it is an authentic moral position they hold.
Plenty of people genuinely dislike the disregard for labor and intellectual property rights that anything Gen AI represents. Again, an authentic moral position.
"Virtue signaling" is for example, when a corporate entity doesn't authentically support diversity through any kind of consequential action but does make sure to sponsor the local pride event (in exchange for their logo being everywhere) and swaps their social media logos to rainbow versions.
vlovich123
I believe it meets the definition of virtue signaling to express a position you don’t do anything to advocate - which is the vast majority of opinions expressed on the Internet. It can be a sincerely held belief but if you’re not taking action around it I don’t see any difference from the corporate example you gave.
eric_cc
When you make these tribal, political comments in a thread like this one - signaling your virtues - what do you prefer us to call it?
amarant
None of those points are even remotely relevant in this case, unless you're worried about dolphin-English translators losing their livelihood?
Mindlessly parroting such talking points where they're not applicable is also a form of virtue-signalling.
And the comments in this thread are predominantly such virtue signalling nonsense.
smitty1e
> Plenty of people genuinely dislike the concentration of economic and computing power that big tech represents.
The harder question that of risk management between the computing power we like on the one hand and its tendency to enable both megalomaniacs at the high end, and the unspeakable depravity of child pornography at the low.
stevage
> It's trendy to hate Google,
Calling something "trendy" is a great way to try to dismiss it without actually providing any counterargument. The deep suspicion of anything Google does is extremely well justified IMHO.
amarant
Well enlighten me then, What's wrong with helping marine biologists trying to make sense of dolphin language?

Google is where great technology and innovation goes to die.
Please give me one example in the last decade where meta or Google research has led to actual products or open-sourced technologies, and not just expensive proprietary experiments shelved after billions were spent on them?

Regardless of your or my feelings on this specific topic, "virtue signalling" is good because virtue is good and signalling to others that we ought to be good is also good. The use of that term as a pejorative is itself toxic cynicism
lukev
It's not even about the communication! Just having more insight into the brains and communication of other mammals has a ton of scientific value in its own right.
Sometimes it's good just to know things. If we needed to find a practical justification for everything before we started exploring it, we'd still be animals.
davedigerati
I for one am simply happy to see us trying to apply LLMs to something other than replacing call centers... humankind SHOULD be exploring and learning sometimes even when there isn't an ROI.
janalsncm
Don’t understand the cynicism either. Is this not way cooler than the latest pre-revenue series F marketing copy slop bot startup?
To me this task looks less like next token prediction language modeling and more like translating a single “word” at a time into English. It’s a pretty tractable problem. The harder parts probably come from all the messiness of hearing and playing sounds underwater.
I would imagine adapting to new vocab would be pretty clunky in an LLM based system. It would be interesting if it were able to add new words in real time.

The ability to understanding bee's communication was made possible, so I'm not sure why dolphins would seem harder?

I work at Google on the Gemma team, and while not on the core team for this model, participated a bit on this project.
I personally was happy to see this project get built. The dolphin researchers have been doing great science for years, from the computational/mathematics side it was quite neat see how that was combined with the Gemma models.
moffkalast
It's great that dolphins are getting audio decoders in language models first, does the Gemma team intend to roll that out for human speech at some point eventually too?

Not directly related, but one of those stories that is so bizarre you almost can't believe it isn't made up.
There was a NASA funded attempt to communicate with Dolphins. This eccentric scientist created a house that was half water (a series of connected pools) and half dry spaces. A woman named Margaret Howe Lovatt lived full-time with the Dolphins attempting to learn a shared language between them.
Things went completely off the rails in many, many ways. The lead scientist became obsessed with LSD and built an isolation chamber above the house. This was like the sensory deprivation tanks you get now (often called float tanks). He would take LSD and place himself in the tank and believed he was psychically communicating with the Dolphins.

>A woman named Margaret Howe Lovatt lived full-time with the Dolphins attempting to learn a shared language between them.
She also had sex with a male dolphin called Peter.
>He would take LSD and place himself in the tank and believed he was psychically communicating with the Dolphins.
He eventually came to believe he was communicating with a cosmic entity called ECCO (Earth Coincidence Control Office). The story of the Sega game "Ecco the Dolphin" [1] is a tongue-in-cheek reference to this. I recommend watching the Atrocity Guide episode on John C. Lily and his dolphin "science" [2]. It's on par with The Men Who Stare at Goats (the non-fiction book [3], not the movie).

It's funny you were thinking that, because I was thinking, "how would you teach a japanese man english?." The obvious answer is to jerk him off and give him high doses of LSD first. I immediately came to the same conclusion with this AI-dolphin stuff. Have they tried jerking off the dolphin and giving it LSD first? Apparently - yes.

arguably the best episode of Drunken history has duncan trussel retelling this story: https://www.youtube.com/watch?v=p7ruBotHWUs
Paraphrasing carl sagan: "You don't go to Japan and kidnap a Japanese man start jking him off, give him fing acid, and then ask him to learn English!"

Know the story. Such a tragic end.

And it's a story that haunts the marine biology field. Imagine having to explain that one every time someone asks about it.

Oh yeah, imagine having to explain an experiment you had nothing to do with, that happened before you were born.
Imagine having to explain dragnet surveillance every time someone finds out you know how to code.
Imagine having to explain the Exon Valdez every time someone asks you about your car.
Roll out the reparations!
lukev
Tangential, but this brings up a really interesting question for me.
LLMs are multi-lingual without really trying assuming the languages in question are sufficiently well-represented in their training corpus.
I presume their ability to translate comes from the fact that there are lots of human-translated passages in their corpus; the same work in multiple languages, which lets them figure out the necessary mappings between semantic points (words.)
But I wonder about the translation capability of a model trained on multiple languages but with completely disjoint documents (no documents that were translations of another, no dictionaries, etc).
Could the emerging latent "concept space" of two completely different human languages be similar enough that the model could translate well, even without ever seeing examples of how a multilingual human would do a translation?
I don't have a strong intuition here but it seems plausible. And if so, that's remarkable because that's basically a science-fiction babelfish or universal translator.
glomgril
Check out this recent benchmark MTOB (Machine Translation from One Book) -- relevant to your comment, though the book does have parallel passages so not exactly what you have in mind: https://arxiv.org/pdf/2309.16575
In the case of non-human communication, I know there has been some fairly well-motivated theorizing about the semantics of individual whale vocalizations. You could imagine a first pass at something like this if the meaning of (say) a couple dozen vocalizations could be characterized with a reasonable degree of confidence.
Super interesting domain that's ripe for some fresh perspectives imo. Feels like at this stage, all people can really do is throw stuff at the wall. The interesting part will begin when someone can get something to stick!
> that's basically a science-fiction babelfish or universal translator
Ten years ago I would have laughed at this notion, but today it doesn't feel that crazy.
I'd conjecture that over the next ten years, this general line of research will yield some non-obvious insights into the structure of non-human communication systems.
Increasingly feels like the sci-fi era has begun -- what a time to be alive.
ahartman00
>lots of human-translated passages in their corpus
Yes. I remember reading that the EU parliamentary proceedings in particular are used to train machine translation models. Unfortunately, I cant remember where I read that. I did find the dataset: https://paperswithcode.com/dataset/europarl
beernet
My hunch is it would work somewhat, but poorly.
Languages encode similar human experiences, so their conceptual spaces probably have natural alignments even without translation examples. Words for common objects or emotions might cluster similarly.
But without seeing actual translations, a model would miss nuances, idioms, and how languages carve up meaning differently. It might grasp that "dog" and "perro" relate to similar concepts without knowing they're direct translations.
lukev
To agree and extend, that's actually how human language works too. The cultural connotations of "dog" in english might be quite different from "perro".
And it gets even more complex because the connotations of "dog" in the USA in 2025 are unquestionably different from "dog" in England in 1599. I can only assume these distinctions also hold across languages. They're not a direct translation.
Let alone extreme cultural specificities... To follow the same example, how would one define "doge" now?
Imnimo
This sounds very cool at a conceptual level, but the article left me in the dark about what they're actually doing with DolphinGemma. The closest to an answer is:
>By identifying recurring sound patterns, clusters and reliable sequences, the model can help researchers uncover hidden structures and potential meanings within the dolphins' natural communication — a task previously requiring immense human effort.
But this doesn't really tell me anything. What does it mean to "help researchers uncover" this stuff? What is the model actually doing?
bjt
As far as I can tell, it hasn't actually done anything yet.
The article reads like the press releases you see from academic departments, where an earth shattering breakthrough is juuuuust around the corner. In every single department, of every single university.
It's more PR fluff than substance.
xnx
Cool to see the use of consumer phones as part of the setup. Having a suite of powerful sensors, processing, display, and battery in a single, compact, sealed package must be immensely useful for science.
sarreph
I’m pretty sure by the time we decode what they’re saying it’ll be “so long, and thanks for all the fish”
nottorp
That's the good outcome.
The bad outcome is the "AI" will translate our hellos as an insult, the dolphins will drop the masquerade, reveal themselves as our superiors and pound us into dust once and forever.
Picture the last surviving human surrounded by dolphins floating in the air with frickin laser beams coming out of their heads... all angrily asking "why did you say that about our mother?".
And in the background, ChatGPT is saying "I apologize if my previous response was not helpful".
engineer_22
This crowd seems to be cross pollinated with the sci-fi / space exploration set. Communication with cetaceans seems like such an obvious springboard for developing frameworks and techniques for first contact with E.T. /If/ you believe they're out there... And if not, what an incredible opportunity in its own right.
But, since context is so important to communication, I think this would be easier to accomplish with carefully built experiments with captive dolphin populations first. Beginning with wild dolphins is like dropping a guy from New York City into rural Mongolia and hoping he'll learn the language.
srean
Can a powerful model become a fantastic autocomplete for dolphins ? Sure. Someday soon that's very likely to happen. But that alone would tell us almost nothing of what dolphin dialogue means.
To understand their language we need shared experiences, shared emotions, common internal worlds. Observation of dolphin-dolphin interaction would help but to a limited degree.
It would help if the dolphins are also interested in teaching us. Dolphins or we could say to the other '... that is how we pronounce sea-cucumber'. Shared nouns would be the easiest.
The next level, a far harder level, would be to reach the stage where we can say 'the emotion that you are feeling now, that we call "anger"'.
We will no quite have the right word for "anxiety that I feel when my baby's blood flow doesn't sound right in Doppler".
Teaching or learning 'ennui' and 'schadenfreude' would be a whole lot harder.
This begs a question can one fully feel and understand an emotion we do not have a word for ? Perhaps Wittgenstein has an answer.
Postscript: I seem to have triggered quite a few of you and that has me surprised. I thought this would be neither controversial nor unpopular. It's ironic in a way. If we can't understand each other, understanding dolphin "speech" would be a tough hill to climb.
ruthvik947
Indeed! As Witt once said, "if a lion could speak, we would not understand it." (https://iep.utm.edu/wittgens/#H5)
finnh
Is it common to abbreviate Wittgenstein to "Witt"? Don't recall seeing/hearing that before, but it's been awhile since undergrad.
Mystery-Machine
The fact that you cannot wrap your head around something doesn't mean that it's not possible. I do not claim that it is surely possible nor that it isn't. But it sure as hell looks possible. You also probably don't have kids. For example: how do you teach a child to speak? Or someone a new language? You show them some objects and their pronunciation. The same with the seagrass and/or a scarf. That's one way. Dolphins can also see (divers with) some objects and name them. We can also guess what they are saying from the sounds plus the actions they do. That's probably how we got "seagrass" in the first place.
For all the word that they don't have in their language, we/they can invent them. Just like we do all the time: artificial intelligence, social network, skyscraper, surfboard, tuxedo, black hole, whatever...
It might also be possible that dolphins' language uses the same patterns as our language(s) and that an LLM that knows both can manage to translate between the two.
I suggest a bit more optimistic look on the world, especially on something that's pretty-much impossible to have any negative consequences for humanity.
srean
Calm down. No need to be rude and condescending and throw personal insults.
If you had read this part --
"But that alone would tell us almost nothing of what dolphin dialogue means.
To understand their language we need shared experiences, shared emotions, common internal worlds. Observation of dolphin-dolphin interaction would help but to a limited degree."
it ought to have been clear that what I am arguing is a corpus of dolphin communication fed to an LLM alone will not suffice. A lot of investments have to be made in this part -- To understand their language we need shared experiences, shared emotions, common internal worlds.
I am sure both you and me would be very happy the day we can have some conversation with dolphins.
Mystery-Machine
That's exactly the argument here. You do not think this is possible. I think it _might be_. You believe we cannot understand their language because we don't have "shared experiences" (etc). I believe we can. That's the disagreement. AI can learn/predict/invent new things. It already is inventing new materials, new protein structures, etc. We don't need to understand the exact mechanism 100% for it to be able to do it. Let's give it a shot.
There are tons of shared experiences and shared emotions. It's not like there's some hidden organism that we discovered are making noise from within the dark matter. These are animals in the oceans. Plenty of shared experiences and emotions. Dolphins have feelings. Anyway... let's agree to disagree. I fully support this project and am optimistic about its outcomes.

I think you are describing more of an edge case than you might think for a vertebrate, mammal, social, warm blooded, air breathing, earth living, pack hunter.

Yes there is a lot we have common, especially the social part. But our worlds and primary senses are really very different.
Even a limited success would gladden my heart.

>To understand their language we need shared experiences, shared emotions, common internal worlds
Why? With modern AI there exists unsupervised learning for translation where you don't have to explicitly make translation pairs between the 2 languages. It seems possible to eventually create a way to translate without having to have a teaching process for individual words like you describe.

The experiment design sounds pretty cool. I hope they see some cool results. It would be very cool if humans could talk to another intelligent creature here on earth. This is certainly a step on the way there.
summerlight
I wonder what's the status quo on the non-LLM side; are we able to manually decode sound patterns to recognize dolphin's communication to some degree? If that's the case, I guess this may have a chance.
Wow, there's a lot of cynicism in this thread, even for HN.
Regardless of whether or not it works perfectly, surely we can all relate to the childhood desire to 'speak' to animals at one point or another?
You can call it a waste of resources or someones desperate attempt at keeping their job if you want, but these are marine biologists. I imagine cross species communication would be a major achievement and seems like a worthwhile endeavor to me.
