🪜 Daechung English training
Daechung English’s three core methods are speed-listening, shadowing, and automatic memory — making things stick without memorizing. The training that actually implements this is the 5-step method. Each step runs at variable speed in the app, and all use uncompressed original WAV.
Steps 1–3 are input training — see and hear English first; steps 4–5 are output training — going from Korean out to English.
There is a reason for cutting training material into 100 sentences. The distinct words in 100 basic conversation sentences number roughly 200 — because the same words keep returning ([[fifty-words-english]]). You meet the same sounds from many angles without the burden of new words, and skimming one set at 2× takes only a few minutes, so you can run it several times a day. It is a design that has you pass the same thing many times instead of adding volume.
Whether speed-listening, shadowing, or audio composition, the speed “where you catch about 50%” gives the greatest improvement. When 2× reaches 80%, drill 3× (30–50% at first) intensively; when 3× reaches 80%, take on 4×. Listening goes to 4×; reading and audio composition are fine at 3×. Korean speed-listening goes to 5×–6×.
The third of Daechung English’s three principles is “keep it short.” Rather than one long block, train in three 10-minute sessions a day (30 minutes total). It works on the commute or amid chores, and it ends before the brain tires, so it keeps going day after day — a 30-day habit opens the ear.
Audio composition and the 1-minute speech are also training in how fast you react to a stimulus. The gap in reaction speed between an ordinary person and a pro gamer is about 0.1 seconds. In an experiment on the MBC documentary *The Sound of Life: Analog*, a high-schooler listened to MP3 music for just 10 minutes and their reaction speed slowed by 0.087 seconds — the reason Daechung English makes its training audio in original WAV, not MP3. Above 3×, WAV is clearly more audible than MP3.
A child starts from two words, “mama, food,” and only later moves to perfect sentences. We learned our mother tongue that way, yet with English alone we demand perfection from the start, so the mouth won’t open. Speaking in two or three words, grammar right or not, and moving forward — that is Daechung English’s philosophy.
