The International Phonetic Alphabet, or IPA, is a notation system that uses symbols to represent the sounds of spoken language. Each symbol corresponds to a distinct sound, and as long as you know the symbol-to-sound correspondence, you should be able to pronounce any word you encounter.

Unlike the International Phonetic Alphabet (IPA), which seeks to use as few diacritics as possible for phonemic distinctions, restricting diacritics to phonetic detail, the Americanist notation relies on diacritics for basic consonants and vowels.
Currently, the IPA consists of 107 sound symbols, 52 diacritics (accents) and 4 prosodic marks (intonations) encompassing virtually every phoneme used in every language on the earth.
