The transcription conventions we use conform to the International Phonetic Alphabet (IPA). The transcriptions you'll find in this website are similar to those in Oxford dictionaries, for instance. For the sake of consistency, we'll conform to these conventions, although in American English, vowels and diphthongs may be pronounced differently.
A special adaptation we'll be using concerns the transcription of post-vocalic /r/ as in the words car, here, air... In this case, a superscript ʳis used, and the words in question are transcribed as /kɑːʳ/, /hɪəʳ/,and /eəʳ/.
Differences between British and American EnglishVideo
You may come across desriptions of English sounds that include triphthongs. This is generqlly the case of teh sounds aɪə and aʊə. A good example in which this difference is significant is the pair "quite" /kwaɪt/ and "quiet" /kwaɪət/.
