It is to be noted that the way English is pronounced by the people of South East England is accepted/received as the standard variety of English. This variety is also called RP - Received Pronunciation of English.
There are 44 sounds in English. (These include 24 consonant sounds and 20 vowel sounds - 12 are pure vowel sounds and 8 sounds are called diphthongs )
When we speak English words, we speak in syllables. Syllables are combinations of sounds always having a vowel sound. Some words are mono-syllabic, some are di-syllabic, tri-syllabic, poly-syllabic.
While speaking words we also emphasise or STRESS certain syllables. These stressed syllables are heard more clearly than the unstressed ones.
While speaking we also change the tone of our voice ie., our pitch rises and falls just like in singing. This is done to show emotions, politeness, power etc.
