This is a cheat sheet for cramming the basic phonemes of Korean. It’s a printable PDF, and a first draft. I’ve noted the approximate sounds in English and Hindi, because Hindi has a better phonetic alphabet. It’s mostly based on this guy’s YouTube video. (He doesn’t give his name, and I’m not going to look for it.) I number the order of the phonemes in the syllable blocks, rather than using his LRB/TMB system. Corrections welcome.
