Vowel sounds are notorious for varying between one variety of English and the next, often being a key element in what we recognize as different accents. So, you may feel that some of the words offered in the earlier lists as examples don’t seem to be pronounced with the vowel sounds exactly as listed. Also, some of the sound distinctions shown here may not even be used regularly in your own speech. It may be, for example, that you make no distinction between the vowels in the words caught and cot and use [ɑ] in both. You may also be used to seeing the vowel sound of pet represented as [e] in dictionaries rather than with [ɛ] as used here.

You may not make a significant distinction between the central vowels [ə], called “schwa,” and [ʌ], called “wedge.” If you’re trying to transcribe, just use schwa [ə]. In fact, in casual speech, we all use schwa more than any other single sound.

There are many other variations in the actual physical articulation of the sounds we have considered here. The more we focus on the subtle differences in the actual articulation of each sound, the more likely we are to find ourselves describing the pronunciation of small groups or even individual speakers. Such subtle differences enable us to identify individual voices and recognize people we know as soon as they speak. But those differences don’t help us understand how we are able to work out what total strangers with unfamiliar voices are saying. We are clearly able to disregard all the subtle individual variation in the phonetic detail of voices and recognize each underlying sound type as part of a word with a particular meaning. To make sense of how we do that, we need to look at the more general sound patterns, or the phonology, of a language.
