The English vowels are A, E, I, O, & U. (Sometimes Y is a vowel, pronounced as if it were I, and sometimes W substitutes for U, especially in the digraph 'ow.') Each vowel can be pronounced in several ways.This page explains when each sound is commonly used.

The most common sound for each vowel is its “short” sound:
(The International Phonetic Alphabet symbol for each sound is inside the backslashes://. You do not need to understand the IPA symbols; just look for an example word you know how to pronounce. For those who want more, this Wikipedia article gives a fairly simple demonstration of the IPA as used in English, with links to more detailed information.)
When syllables end in a vowel and then consonant (as in the examples above), the vowel is usually short. If there is more than one consonant, the vowel is almost always short.
This becomes important as a way to keep the same vowel sound when adding -ed to put a verb into the past tense. We often double an ending consonant to keep a short vowel short. For example, the past tense of 'stop' is 'stopped.' Otherwise the silent 'e' rule below (which also applies when followed by 'd') would give it a long 'o' sound like soap or hope. See the Simple Past Tense explanation of spelling changes.
The alphabet sounds (when the vowel “says its name”) are called “long vowels.”
We call them ‘long’ because we hold them longer than the short sounds.
However, they are completely different sounds-- not a longer version of the same sound.
Silent ‘E’ Rule: When a vowel and consonant are followed by an ‘e’, the ‘e’ is almost always silent, but it causes the preceding vowel to be long. (Examples: ate, plane, Pete, bite, nine, rope, note, cube, flute.)
Other Long Vowels: A vowel at the end of a syllable is almost always long. Examples: I, we, he, she, go, try, potato and tomato. (Some English speakers use a short ‘a’ in the 2nd syllable, while others use a long ‘a,’ but both ‘o’s are long for everyone.)
-Igh and -ight are usually long I (and silent GH): bright, fight, high, light, might, night, right, sigh, sight, tight.
Often the first letter of the vowel combinations, especially ‘ai’, ‘ay’, ‘ea’ (sometimes-- see Digraphs, below), ‘ee’, & ‘oa,’ will be long & the second will be silent. (An old rhyme for children says “when 2 vowels go walking, the first does the talking.”) So ’plain’ sounds just like ‘plane,' ‘meat’ and ‘meet’ like ‘mete,’ etc.
However, there are many exceptions. (See the link to English Vowel Digraphs, at the bottom of this page, for the most common ones.)
These contrasts demonstrate the rules (in each column, first short, then long):
Besides the long and short sounds, there are other vowel sounds.
Any vowel in an unaccented syllable has a neutral or “schwa” /ə/ sound: Examples: the ‘a’ in above, or approve, the ‘e’ in accident, camera or mathematics, the ‘i’ in family or officer, the ‘o’ in freedom or purpose, or the ‘u’ in industry or succeed.
if a vowel is followed by R, it changes in quality, and is neither long nor short. (ER, IR, and UR are often -- though not always--the same sound.)
Examples with phonetic symbols:
Quite a few common words spelled with ‘O’ are pronounced with a short ‘U’ sound: of, love, money, other, some, son. (That means some and sum are homophones: they are pronounced the same. So are son and sun.) See the course below for more examples and practice.
Different English dialects pronounce certain vowels differently than the general rules given above. For example, in California and much of the U.S., the ‘a’ in ‘father’ or ‘want’ is pronounced very much like the ‘au’ in ‘audio’ or the short ‘o’ in ‘pot’ or ‘hot.’ That’s not true for all English speakers, however.
Another example: the /ɜr/ in bird, burn, earth, etc. is generally pronounced /ər/ in the U.S. and some other areas.
Don't worry about these differences. English speakers can almost always understand people speaking other dialects of English without difficulties. If you live in any area for a while, you'll be able to adjust to them-- and most are not very different.
For the exact pronunciation of any word, consult a good dictionary. Most list the sound symbols they use on one of the front pages. Good online dictionaries like the Oxford Advanced Learner's Dictionary will let you listen to the pronunciation. (This dictionary gives both British and Amerian pronunciations of each word.)
Are you interested in learning more about the relationship between English vowel sounds and spellings?
There have been so many positive comments on this page that I’ve decided to design a short course about it. It can help you recognize more of the words you know when you read them. It will also help you spell better and pronounce new words.
After the course overview there’s a short lesson about homophones (words that sound the same but have different meanings and often different spellings} and an introduction to short and long vowels that expands a little on this page.
Most importantly, it also teaches a way I just learned to remember the different vowel sounds using colors.* It identifies each sound with a color and image that use the same sound: 'black hat' for short A and 'white light' for long I. These are easier for most of us than learning the International Phoenetic Alphabet.
The Vowel Sounds and Spellings course includes lessons on the ways each vowel (and its digraphs) can be pronounced and spelled, including times when a letter is used for a different vowel sound. There’s also a lesson on Vowels followed by Rs.
It costs $12 and includes opportunities to ask questions, practice, and take quizzes to see if you understand. There's also a 100% refund for the first two weeks if you try the course and are disappointed.
There are two sample ("free trial") lessons on the sounds of 'A' (as well as a free introductory video) so you can see how the course works. It should make English pronunciation and spelling simpler for you.
If there are certain things you especially want to learn about vowel sounds or spelling, you can also leave a comment or question in the box below.
If you would like, you can also download a pdf (as requested in the comments) with an expanded section on the short and long vowels from this page. (It adds color images to help you recognize each sound, as mentioned in the course informtion above).
English has adopted words (and often some of their sounds), from so many other
languages, none of these rules is always true.
However, these English vowel rules will help you guess at the pronunciation of words you read. For that reason, they may also help you guess their meaning, if you have heard them but not read them before. They should also help make English spelling a little easier.
*P.S. For more information on associating vowel sounds with colors see this color vowel chart. It also links to the website of the teachers who designed the chart. They provide more information and offer free and paid courses (and materials) to help teach this system to children or ESL students.
