The various English dictionaries use different and sometimes conflicting IPA transcriptions for English. For example, the transcription /i/ may be used for the vowel of sit, of seat, or at the end of city. A dictionary may not even be consistent between one edition and the next. This table correlates the more widely used dictionaries with the conventions of the IPA key that is used on Wikipedia.
Most dictionaries transcribe a specific dialect or accent, such as the Received Pronunciation (RP) of the Oxford English Dictionary, or a narrow range of dialects. Wikipedia's IPA key, on the other hand, is intended to cover RP, General American, Australian, and other national standards. As such, Wikipedia transcribes /r/ where it is found in rhotic dialects, but also the vowel distinctions found in non-rhotic dialects, without distinct UK and US transcriptions. Specific dialects may also be transcribed—local pronunciations of place names are often useful, for example—but they are normally written in addition to a more universal pronunciation.
When entering IPA in an article, please use the {{IPA}} template so that it is formatted properly on all web browsers. /Slashes/ and should be included inside the IPA template, so that they display in the same font as the IPA itself. Also, please use proper stress ˈ and length ː marks (available at the bottom of your edit window) rather than the non-IPA shortcuts of apostrophe ⟨'⟩ and colon ⟨:⟩; depending on the reader's font preferences, the latter can be ambiguous.
For a list of those languages other than English which have agreed-upon transcriptions in Wikipedia, see {{IPA keys}}. For a comparison of the non-IPA transcriptions found in many US dictionaries, see Pronunciation respelling for English.
Alternative pronunciations
When dictionaries give alternative pronunciations, they may mean that people disagree. For example, some people pronounce bath /bæθ/, with the vowel of bat, while others with the same accent pronounce it /bɑːθ/, with the vowel of bra. This is the kind of difference celebrated in "You like to-may-toes; I like to-mah-toes". On Wikipedia, we would normally need to transcribe both, unless only one is considered correct, as may be the case for personal and place names.
However, often variant transcriptions reflect distinctions between accents, and these we do not need to transcribe, since our IPA key already covers such distinctions. For example, Merriam-Webster transcribes merry as "/ˈmɛri/" and marry as "/ˈmɛri, ˈmæri/". The two transcriptions of marry are meant to show that some people pronounce it the same as merry; it does not mean that there are two pronunciations of marry among those who either do or do not make this distinction (see Mary–marry–merry merger). It would not be possible to have the song lyric "You say marry and I say merry", because only those people who say those words differently would be able to sing it. Therefore on Wikipedia we would only have one transcription for each: merry /ˈmɛri/, marry /ˈmæri/. Since the IPA key defines the orthographic conventions of /ɛr/ and /ær/ according to basic English words, readers who do not make the marry–merry distinction will see /ɛr/ and /ær/ as being equivalent, much as the spelling pronunciations YOU-clid and EWE-clid for "Euclid" would be seen as equivalent.
Consonants
Consonants vary little between dictionaries. The ones which do are those in the words:
- rich, char /r ~ ɹ ~ (r) ~ (ɹ) ~ ∅/;
- which, /ʍ ~ hw ~ (h)w ~ w/;
- and new, /juː ~ uː/.
Wikipedia editors have decided to go with /rɪtʃ/, /tʃɑːr/, /hwɪtʃ/, /njuː/ for these words.
A few dictionaries, such as dictionary.com, use "/y/" for /j/, which is at odds with the official IPA usage, which defines /y/ as close front rounded vowel (as in French tu or German über), and appears as such in transcriptions of French and German, as well as some dialects of English.
Vowels
The following tables compare the broad IPA pronunciation scheme of some dictionaries to the one used on Wikipedia. The overview is not exhaustive, but major pronouncing dictionaries have been included. Highlight colors:
- Green highlights pronunciation symbols that are the same as on Wikipedia (disregarding a syllable divider when it does not mean a two-syllable pronunciation, but only that the /r/ belongs to the next syllable, and disregarding different symbolizations of the syllable divider or of /r/);
- yellow highlights pronunciation symbols that differ only in the use of the length symbol ⟨ː⟩, in parentheses, in superscripts, in non-rhotic dropped /r/, or in inserting an optional sign;
- red highlights pronunciation symbols that use different signs.
Other conventions:
- A question mark (?) means that the sound has not been found in the respective dictionary.
- A blank cell means that the dictionary has not been checked.
- A slash (/) separates variant pronunciations signs. The order of the variant pronunciation symbols is the same as in the source.
- Smaller text (like so) highlights variant pronunciations that are not preferred (only some dictionaries make such a distinction).
- A comma (,) separates different pronunciation depending on the word or depending on the region. The differences are explained in a footnote or by broadly specifying the region.
