It is often stated that English has a particularly large number of vowel phonemes and that there are 20 vowel phonemes in Received Pronunciation, 14–16 in General American, and 20–21 in Australian English. These numbers, however, reflect just one of many possible phonological analyses. A number of "biphonemic" analyses have proposed that English has a basic set of short (sometimes called "simple" or "checked") vowels, each of which can be shown to be a phoneme and which can be combined with another phoneme to form long vowels and diphthongs. One of these biphonemic analyses asserts that diphthongs and long vowels may be interpreted as comprising a short vowel linked to a consonant. The fullest exposition of this approach is found in , where all long vowels and diphthongs ("complex nuclei") are made up of a short vowel combined with either (for which the authors use the symbol ), or (plus for rhotic accents), each thus comprising two phonemes. Using this system, the word "bite" would be transcribed , "bout" as , "bar" as and "bra" as . One attraction that the authors claim for this analysis is that it regularizes the distribution of the consonants , , and (as well as in non-rhotic accents), which would otherwise not be found in syllable-final position. suggest nine simple vowel phonemes to allow them to represent all the accents of American and British English they surveyed, symbolized (front vowels); (central vowels); and (back vowels).
