Description:

This cloze exercise randomly selects two out of 18 Cardinal vowels and then uses three single-choice elements each to describe their parameters. It is particularly well-suited for drop-down menus and also illustrates how Unicode symbols can be used for the phonetic transcriptions in the International Phonetic Alphabet (which requires the fontspec package in XeLaTeX for PDF output).
