Week 1 to 2, then forever as background
Hear the music
Train your ear to recognize the rhythm, melody, and sound inventory of English before you ask it to mean anything.
Six-month-old babies can distinguish English R and L. By twelve months the brain filters out sounds that don't belong to the language it hears. Re-opening that filter as an adult takes long, unhurried exposure.
Play English in the background while cooking, walking, commuting. Do not try to understand anything. Vary the source: news, podcasts, songs, series.
Phoniq: Ambient audio at your interest level, no transcript. Only metric that matters this fortnight: minutes of exposure.
