Goneril, one of the daughters of King Lear, is difficult to pronounce. It is often mispronounced by placing too strong of an emphasis on the "i" in the last syllable of the name. The first link that I have placed below is to a web site that has recordings of a variety of Shakespearean characters who are difficult to pronounce including Oberon, Titania, and others. If you often have difficulty pronouncing words, this website provides audio examples for many difficult names and words. It is a fantastic resource.
