For me, this is one of the greatest triggers when it comes to creating that wondrous sensation that we call tingles, or AIE, or ASMR. So many names…
I find that only certain radio stations actually do it for me though. From where I am right now, in South Africa, I sometimes listen to the Afrikaans radio stations, even though it’s not my first language. English is.
I usually tune in to 103. or 104. and listen to those stations. I can understand some Afrikaans, and I found that listening to these stations does tend to improve my understanding or vocabulary in that language. Not only that, but it creates the sensation. It’s a sort of guttural language with emphasis on the “g” mainly. It sounds like you’re clearing your throat.
It’s been said by others that listening to foreign languages often creates the sensation. Particularly when it’s spoken by someone with a nice voice. And let’s face it – people, especially those who are the DJs or whatever you want to call them, are employed because they have a voice, and perhaps a face, for radio.
