There has been academic interest in dialects since the late 19th century. The main works are "On Early English Pronunciation" by A.J. Ellis, "English Dialect Grammar" by Joseph Wright, and the "English Dialect Dictionary" also by Joseph Wright. The Dialect Test was developed by Joseph Wright so he could hear the differences of the vowel sounds of a dialect by listening to different people reading the same short passage of text.
