Phonetics: Consonants, Vowels, Diphthongs, IPA Chart definition and .. Think of the following chart as a diagram of the mouth facing left. Vowels are conventionally arranged on a two-dimensional diagram, where the . there should be a one-to-one relationship between sounds and IPA symbols. A vowel diagram or vowel chart is a schematic arrangement of the vowels. Depending on the particular language being discussed, it can take the form of a.
While consonants can at least be described with precise terms and actions, vowels tend to be more of approximations in the IPA.
Describing English vowels
This is because vowels tend to lie more on a spectrum than consonants, and also because vowels can change subtly from accent to accent and from language to language. However, these subtleties can make a noticeable difference to our ears. Because I personally am an American English speaker, I am most familiar with the standard American accent General American and some of its variations, as well as the standard British accent Received Pronunciation.

So some of the following examples will mostly serve as a way to get you familiar with some of these IPA symbols. But even the same symbol can represent slightly different vowels, since, as mentioned before, vowels tend to lie on a spectrum. Really, it is best to use your ears to listen to how English is spoken by different people, and then compare that to the IPA symbols.
Three major factors in the production of vowels are the openness, or height, of the mouth, the position of the tongue, and the roundness of the lips. If a vowel is produced while the mouth is almost closed, it would be considered a close If the vowel is slightly more open, it would be considered a mid vowel. And if the mouth is open very tall, it would be considered an open vowel. If the tongue is positioned near the front of the mouth, any vowel produced would be a front If the tongue were set slightly more back in the mouth, the vowel would be a central vowel.
If the tongue were set in the far back of the mouth, the vowel would be a back vowel.
If a vowel is produced while the lips are tense and rounded, it would be considered a rounded. If the vowel is produced while the lips are relaxed, it would be considered an unrounded vowel. Think of the following chart as a diagram of the mouth facing left sideways, where the position of the tongue traces along the different points to produce different vowels. However, English is a language known for being full of diphthongs double vowels that are represented by combinations of symbols.
Rounding is important because it continues to help differentiate the vowels of English. For example, for [u], the lips are rounded, but for [i], the lips are spread. Vowels can be categorized as rounded or unrounded. Usually, there is a pattern of even distribution of marks on the chart, a phenomenon that is known as vowel dispersion.
For most languages, the vowel system is triangular. Such a diagram is called a vowel quadrilateral or a vowel trapezium. 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.
English vowel chart
Spectral properties are the speech sound's fundamental frequency and its formants. Each vowel in the vowel diagram has a unique first and second formant, or F1 and F2. The frequency of the first formant refers to the width of the pharyngeal cavity and the position of the tongue on a vertical axis and ranges from open to close. The frequency of the second formant refers to the length of the oral cavity and the position of the tongue on a horizontal axis. The F2 frequency is higher for [i] because the oral cavity is short and the tongue is at the front of the mouth.
The F2 frequency is low in the production of [u] because the mouth is elongated and the lips are rounded while the pharynx is lowered. By definition, no vowel sound can be plotted outside of the IPA trapezium because its four corners represent the extreme points of articulation.
The vowel diagrams of most real languages are not so extreme.
