SpeakLines turns sitcom dialogue into an English study list

Field notes

The scoring factors are multiplied together, so a rare word or a line that depends heavily on its scene can lower the result. The list is assembled one line at a time, and the page describes a word as no longer counting toward new learning after it has appeared three times. Its reported tests use later seasons as holdouts; the site also cautions that coverage counts known words, not listening comprehension.
