Vowel sounds are made by putting your tongue in a certain position in your mouth so that the air from your lungs can flow out freely. For open vowels such as /ɑ/ as in "bought" you open your mouth by lowering your jaw. For close vowels, you keep your mouth more closed. To make the front vowels such as /i/ as in "beat" you put the tip of your tongue near the front of your mouth. To make a rounded vowel, such as /u/ as in "boot," you round your lips into a circle.
These are the main vowels in my dialect of English, Canadian.

People who speak English dialects pronounced vowels differently depending on where they are from while in general, they pronounce most consonants the same. In Canada, from Ontario to British Columbia most English speakers use Standard Canadian English. Standard Canadian is marked by the cot/caught merger, Canadian raising (starting the vowel high in words such as bite and about) and the Canadian shift (lowering short front vowels).
In Canada and some parts of the U.S., the words "bot" and "bought" are pronounced the same. U.S. dialects often say the two words differently, eg. bot /bɒt/ vs. bought /bɔt/. In Received Pronunciation in southern England, "bot" is pronounced /bɒt/ with more rounding than in North American English, and "bought" is pronounced /bɔːt/ with a slightly longer sound than in North American English.
Another feature of Canadian English is Canadian raising. The word "bite" is pronounced /bǝit/ with the tongue starting in the middle of the mouth. In Standard American, the tongue starts lower /bait/. In Canada, the word "about" can be pronounced /ǝbʌut/ again with the tongue starting a bit higher than other dialects. In Standard American, it is pronounced /əbaʊt/ with the tongue starting and finishing a bit lower. In some parts of the American midwest, people also say these words in the Canadian way.
Recently, young speakers have been lowering the short front vowels in something which is called the Canadian shift, pronouncing words such as "bit," "bet" and "bat" with the tongue somewhat lower than their parents. The same thing appears to be happening in California.
There is also a northern cities vowel shift. In the U.S. in northern inland cities such as Chicago and Detroit, for the last hundred years there has been a vowel shift, raising the vowel in "bat" /bæt/ closer to /bɛt/, and fronting the vowel in "bot" /bɑt/ to /bat/.
Canadian English has 12 vowel sounds. Japanese and Spanish have only 5 vowel sounds. Danish is said to have 26 different vowel sounds.

English also has two affricates made by stringing together two sounds, an alveolar plosive followed by a postalveolar fricative: /tʃ/ catch /dʒ/ judge
In bilabial sounds, you put your lips together or round them into a circle. In labiodental sounds, you touch your upper teeth against your lower lip. In dental sounds, you move the tip of your tongue close to the back of your upper teeth. Your alveolar ridge is the hard red ridge just behind your upper teeth. In postalveolar sounds you move your tongue close to the very back of your alveolar ridge where it goes up. The hard palate is the roof of your mouth behind that. Velar is the soft palate at the very back of the roof of your mouth. Glottis is the opening between your vocal cords where your voice comes from.
To make a plosive, you close off the air with your tongue, breathe out, and then release the closure. To make a nasal sound, you lower your velum so the air from your lungs goes out through your nose. To make a fricative, you move your lips or tongue close, but not touching, so that the air becomes turbulent making a hissing sound. In approximants, you keep your tongue fairly far from the roof of your mouth to make a smoother sound with no hissing.
The English 'r' sound is often made by bunching your tongue up, and moving it up closer to your postalveolar ridge, but not close enough to create hiss. This sound is actually fairly rare in the world's languages. Mandarin Chinese has a retroflex fricative /ʐ/ where you bend the tip of your tongue backwards, and make a hiss. Hindi has a retroflex flap /ɽ/ bending the tip of your tongue backwards, and tapping it against the back of the alveolar ridge. Spanish and Japanese have lateral alveolar flaps /ɾ / keeping the sides of the tongue down, while tapping the tip against the alveolar ridge. Arabic and Italian have a trill where the tongue is brought close to the alveolar, but vibrates up and down due to the air passing through.
In Canadian English and Standard American, the 'r' sound is pronounced at the end of words, eg. bar, car, dare. In Received Pronunciation and Boston English, the final 'r' is sometimes not pronounced, i.e. /bɑ:/, /kɑ:/, /dɛǝ/.
