Poem of Linguistic

Linguistics study of language generally  #  Divided into Grammar and Phonology

Phonology is study of speech sound  #   While Grammar in meaningful units of sound

And their arrangements  #  Into longer utterances

But if you want to study  #  You must be with vocabulary

In Phonology when we study a speech sound  #  According to view point there are two kinds

First is Phonetics when study only as sound  #  Second Phonemics if we want to find out

Significant unit which are in utterances  #  That distinguish them are called phonemes

Phonetics is divided into acoustic  #  If we view sounds from physical attributes

And if from ways of production called articulatory  #   It is related by Physics  closely

So in this writing the English Phonetics  #  Just refers to articulatory Phonetics

Knowledge of theories of producing speeches  #   Should be accompanied with exercises
