The English Pronouncing Dictionary (EPD) was created by the British phonetician Daniel Jones and was first published in 1917. [1] It originally comprised over 50,000 headwords listed in their spelling form, each of which was given one or more pronunciations transcribed using a set of phonemic symbols based on a standard accent.
For example, you may pronounce cot and caught, do and dew, or marry and merry the same. This often happens because of dialect variation (see our articles English phonology and International Phonetic Alphabet chart for English dialects). If this is the case, you will pronounce those symbols the same for other words as well. [1]
