Here is a basic key to the symbols of the International Phonetic Alphabet. For the smaller set of symbols that is sufficient for English, see Help:IPA/English. Several rare IPA symbols are not included; these are found in the main IPA article or on the extensive IPA chart. For the Manual of Style guideline for pronunciation, see Wikipedia:Manual of Style/Pronunciation.
For each IPA symbol, an English example is given where possible; here "RP" stands for Received Pronunciation. The foreign languages that are used to illustrate additional sounds are primarily the ones most likely to be familiar to English speakers, French, Standard German, and Spanish. For symbols not covered by those, recourse is taken to the populous languages Standard Chinese, Hindustani, Arabic, and Russian. For sounds still not covered, other smaller but better analyzed languages are used, for example Swahili and Zulu (for the Bantu branch) or Turkish (for Turkic branch) for their respective related languages.
The left-hand column displays the symbols like this: [a] (listen). Click on "listen" to hear the sound; click on the symbol itself for a dedicated article with a more complete description and examples from multiple languages. Consonant sounds are spoken once followed by a vowel and once between vowels.
