"Familiarity controlled Word lists 2003 (FW03)" is a set of 20 lists of 50 Japanese words each in four ranks of word familiarity (for a total of 4000 words). FW03 is useful for evaluating the ability of a person to hear human speech. However, it has been pointed out that the FW03 lists have too many words to evaluate the ability of a person to hear human speech in a short time. This can cause problems, such as when evaluating the ability of an elderly person to hear human speech during a medical exam. To remedy this problem, we propose new word lists that are a subset of FW03. The new lists were created by considering both phonetic balance and word familiarity. Each of the new word lists comprises only 20 words. This reduces the duration of an examination to around two-fifths of a conventional FW03-based examination. Word intelligibility tests suggest that these new lists provide word intelligibility scores nearly equal to those resulting from FW03.
