🗾 Daechung English, 100 Q&A
You came to open your English ears — so why be told to listen to Korean fast? It is the question Daechung English gets most. The root of the answer is in Japan.
Japanese, like Korean, is structurally weak to the high frequencies of English. In that Japan, training in “high-speed listening to the mother tongue (speed-listening)” became a big trend — listen to your native language fast, stimulating the frontal lobe and language centers, and English listening rose along with it. The speed-listening Ossam met in 2009 was on this current.
Play English fast to an ear that can’t hear it, and the brain just blocks it as noise. But play already-known Korean at 4×? The brain runs Wernicke’s language center at full power to make sense of it somehow. Spending no energy on interpreting meaning, the whole load falls only on processing-speed training — that is why you “start English study in Korean.”
Lower the speed because you can’t catch it and you stay in place forever, because the brain adapts to comfort. Conversely, after 4× training, return to normal speed and it comes through crisply, like slow motion. You don’t even need to catch everything at 4× — the aim is not comprehension but a stretch that wakes the stiffened information-processing speed.
Ossam checked whether this principle also holds in Korean by having 12 people do only Korean speed-listening for a month. The result: all improved. Japan’s boom was not chance but the brain’s operating principle — Daechung English’s “Korean speed-listening first” stands on this experiment.
The 13th experiment is in your ears.
