English Pronouncing Dictionary

The English Pronouncing Dictionary (EPD) was created by the British phonetician Daniel Jones and was first published in 1917. 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. The dictionary is now in its 18th edition. John C. Wells has written of it "EPD has set the standard against which other dictionaries must inevitably be judged".
