Read along with native-language or English subtitles to map sound to text

""Watch with subtitles first, then hide them — the second viewing trains your ear without the crutch.""

"Identify the accent first"

Before you understand the words, name the accent — American, British, Australian, or Indian

""Developing accent awareness is the first step; recognition precedes comprehension.""

リスニングのヒント

"Slow down with variable speed"

Use 0.75x playback speed when an accent is unfamiliar, then return to 1x

Record yourself reading the same text as a native speaker, then compare the audio

""Side-by-side recording reveals exactly which phonemes and rhythms need work in your own production.""
