In the vowels chart, a separate phonetic value is given for each major dialect, alongside the words used to name their corresponding lexical sets. The diaphonemes for the lexical sets given here are based on RP and General American; they are not sufficient to express all of the distinctions found in other dialects, such as Australian English.
The number of vowels is subject to greater variation; in the system presented on this page there are 20–25 vowel phonemes in Received Pronunciation, 14–16 in General American and 19–21 in Australian English. The pronunciation keys used in dictionaries generally contain a slightly greater number of symbols than this, to take account of ...
Different vowels vary in pitch. For example, high vowels, such as [i] and [u], tend to have a higher fundamental frequency than low vowels, such as [a]. Vowels are distinct from one another by their acoustic form or spectral properties. Spectral properties are the speech sound's fundamental frequency and its formants.
There are two complementary definitions of vowel, one phonetic and the other phonological.. In the phonetic definition, a vowel is a sound, such as the English "ah" / ɑː / or "oh" / oʊ /, produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and continuant.

The following is the chart of the International Phonetic Alphabet, a standardized system of phonetic symbols devised and maintained by the International Phonetic Association.
The spelling of English continues to evolve. Many loanwords come from languages where the pronunciation of vowels corresponds to the way they were pronounced in Old English, which is similar to the Italian or Spanish pronunciation of the vowels, and is the value the vowel symbols a, e, i, o, u have in the International Phonetic Alphabet.
The official chart of the IPA, revised in 2020. The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script.It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech.
