Researchers have found that 'baby talk' connects all of humanity
It's a language we all speak.

It's almost impossible to be handed a baby and not immediately break into baby talk. In fact, it seems incredibly strange to even consider talking to a baby like one would an adult. Studies have shown that babies prefer baby talk, too.
Researchers from Stanford found that babies prefer to be spoken to in baby talk or “parentese” as scientists refer to the sing-songy cooing we do when talking to infants.
“Often parents are discouraged from using baby talk by well-meaning friends or even health professionals,” Michael Frank, a Stanford psychologist, told Stanford News. “But the evidence suggests that it’s actually a great way to engage with your baby because babies just like it–it tells them, ‘This speech is meant for you!’”
The big question that has eluded scientists is whether parentese is a universal language or varies by culture.
"Most of the research looking at this have studied urban societies in the U.S., Canada, Germany, Sweden, Russia," Courtney Hilton, postdoctoral fellow and principal author of "Acoustic regularities in infant-directed speech and song across cultures," told NPR. "But to make a rigorous claim that there is any kind of instinct to do this, we have to study more diverse cultures."
Hilton, along with a team of researchers, collected 1,615 recordings from 21 cultures across six continents over a period of three years to find out whether parentese was a universal language. Their findings were published in the journal Nature Human Behavior.
What researchers found was that everyone changed their rhythm, volume, speed and other vocal traits when talking to infants. It didn’t matter if they were in San Diego, East Africa, New Zealand or China.

“Our study provides the strongest test yet of whether there are acoustic regularities in infant-directed vocalizations across cultures,” Hilton said. “It is also really the first to convincingly address this question in both speech and song simultaneously. The consistencies in vocal features offer a really tantalizing clue for a link between infant-care practices and distinctive aspects of our human psychology relating to music and sociality.”
So, according to research, if you hand someone a baby anywhere in the world, they would begin to speak to it in parentese, regardless of their culture, location, economic status or language.
The research makes it appear as though parentese is hard-wired into all of humanity. As infants, we seem to be drawn to those who speak it; as adults, we instinctually drop into the vocal patterns when communicating with a baby.
"These commonalities are almost woven into our biology," Hilton said. "From people in crowded urban centers in Beijing, all the way to a tiny hunter/gatherer society in South Africa, there is something we share. It's a kind of instinct that ties people together."
In a world that is divided by race, class, culture, language, politics and geopolitical forces, there’s something comforting in knowing that on a deeper level we all react to infants the same way. It seems that no matter who we are or where we live, babies bring out the best in humanity.
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
