In 1971, an aquarium in the United States took in an orphaned seal. Five years later he started doing something: speaking in English
When you go to an aquarium you expect to find ponds full of picturesque fish, seahorses, jellyfish, dolphins, sharks… Maybe, with luck and depending on where the enclosure is and how big it is, the occasional penguin. Those who went in the 80s to the New England Aquarium from Boston, in the United States, are looking for something different: a English speaking seal. And not. There are no quotes or italics here. Hoover (that was the name of the pinniped) spoke with all the law and in a way so clear that still fascinates today to the experts. Yes indeed, his voice It was not the most harmonious in the world. A talking seal? Exact. Seal and chatterbox are not two words that usually go together. But that is precisely why Hoover aroused so much interest in his day. And that is why even today, 41 years after his death, continues starring reports. Before getting into the subject, it is worth introducing the protagonist. Hoover was a male harbor seal (Phoca vitulina) that a fisherman rescued as a hatchling in the waters of Cumberland County, Maine, and spent most of its life at the New England Aquarium. His story would not be of much interest if it were not for the fact that around 1976, when he was around five years old, the animal began to do something unusual: speak broken English. How is that possible? To understand this, you have to take another leap back in time and go back to May 1971, when George Swallow, a Maine fisherman, did something unconventional: he brought home a baby seal. In theory it was not a whim or an eccentric raving. The poor animal had lost its mother, so Swallow decided to welcome her: He hand-fed her, played with her and (in short) took care of her as if she were a dog. He even gave him a name: Hoover. The problem is that as the seal grew it needed more and more fish, which made it unfeasible for it to continue with the Swallow family. His destination was the New England Aquarium, where he arrived when he was three months old. What did that seal say? Hoover’s life was relatively normal until the mid-1970s. When he was around five years old, the aquarium keepers realized something: the seal was making sounds similar to human speech. “The vocalizations were common especially during the mating season and often seemed intended for females, suggesting that they could have acted as ‘mating songs’, similar to those produced by male harbor seals,” a group of psycholinguists and behavioral biology experts recalled in 2023. a paper published in Current Biology. That observation is interesting. The aquarium staff did not teach Hoover to speak. They also didn’t train her to imitate sounds. It is assumed that what the animal learned about human vocalization was assimilated when it was a baby and lived with the Swallows. Some versions They claim that when the family gave her to the aquarium they had already heard her ‘talk’, but experts usually place her first ‘words’ at the age of five, when she reached sexual maturity. And what exactly did it say? That’s the most surprising thing. As remember From the aquarium itself, Hoover was able to pronounce words like “hello”, “let’s go” or “hey”, all in English. The Guenther Speech Neuroscience Lab even notes that he uttered entire phrases that he probably heard at the Swallow home, such as “Hoover get over here! Come on, come on“. As if that were not surprising, there is one more fact: they say he spoke with a Maine accent. The best thing is that you don’t have to imagine it. Although they are not particularly sharp, we preserve some recordings with Hoover’s chatter. Was he really talking? Often the best way to hear something is to (simply) want to hear it. This has led us, for example, to identify words like “mom” in dog growls either cat meows. In the case of Hoover, Diandra Duengen and the rest of the researchers who sign the article of Current Biology They believe that we are facing something different. It’s not that the seal made a confused sound reminiscent of expressions like “Hello there”, “hurry”, “hey, hey” either “come over here”. No. Everything indicates that it is a deliberate imitation. “Human perception is so fine-tuned to finding speech patterns that some animals can trick our brains into making us hear speech sounds where no such similarity exists,” they explain. “In Hoover’s case there is strong evidence of speech imitation. Spectrograms of his sounds show that his vocalizations were, in fact, very ‘human’, containing the typical formant modulations we use to produce vowels and consonants.” Was it expressed then? No. And yes. Duengen and his companions remember that there is analysis to suggest that Hoover produced sounds similar to English vowels, making it a fascinating case of “learning human speech vocal production in a mammal.” They also believe that the seal could have used this ability as “mating songs”, something that other male seals do. What we cannot say is that Hoover ‘understood’ what he was saying, something that is not necessary for speech imitation in any case. “Comprehension or intention of meaning is not relevant to the learning of vocal production. Neither Hoover nor most other animals that exhibit this learning seem to ‘understand’ spoken language or the meaning of words. However, vocal imitation is impressive in itself and represents a fundamental component of speech,” they point out the experts. That Hoover did not begin to produce sounds until his sexual maturity, even when it came to words that he theoretically learned when he was a child, is also not exceptional. Something similar happens with some birds with the same capacity. Is it just a curiosity? No. In his day Hoover appeared on ‘Good Morning America’ and monopolized reports in Reader’s Digest either The New Yorkeramong many other media. Beyond the picturesque nature of his case, … Read more
