': Vowel and Consonant Sound (Speaking Skill)

Speaking is the way we express our thinking or opinion to the other people. To speak with foreigners especially with English native speakers by using English as interlanguage, we need to be aware of pronunciation. They might not understand what we say if we pronounce the wrong sound (don't overlook easy words)

If we want to speak English as much similar as a native speakers, we need to know how they pronounce each sound and the way they accent each word.

In nearly all languages, words must contain at least one vowel. While a word can be formed without any consonants – such as the English words I or way – no word may consist of only consonants, without a vowel.
A vowel is a type of sound for which there is no closure of the throat or mouth at any point where vocalization occurs. Vowels can be contrasted with consonants, which are sounds for which there are one or more points where air is stopped.

Vowels in many languages are not crucial to the general meaning of the word. Rather, a vowel in these languages – of which many are Semitic languages – acts more to give a specific inflection than to differentiate the word from other distinct words. A parallel of this in English can be seen in the example of dive and dove or lay and lie, in which the core word is the same, but the changed vowel denotes tense. Languages that have this type of structure often do not even mark all of their vowels in written text. Both Arabic and Hebrew are good examples of this, where the marking of many vowels is unnecessary in writing. (http://www.wisegeek.com/what-is-a-vowel.htm)

I have found below clips that teach English sound from youtube. I think he speaks very clear in each sound and show it slowly so that we can hear it clearly and can speak along. The sounds that he taught are the sound that usually ESL learners have a difficulty to pronounce.
