How to improve the spoken English skills?

1.Speak in English: The best way to improve the spoken English skill is to talk in English with others. This will enhance your English language skills. When you can talk easily with another person in English, then you know that you are well conversant in the language.
2.Watch English films: Another better way to learn the language is to see a lot of English movies. When you see the characters speaking in front of you then you tend to learn the language better. The characters speak with different moods and therefore people who listen intently can learn the language better.

Language as a medium of communication:
Language is just a tool and it is a medium of communication. Human beings have from time immemorial learnt the ways for emotional expressions and language is the best means of that expression. Language is the best means of self expression which is bestowed only on the human beings and not on any other beings on the earth. Therefore people can express their thoughts and dreams through self expression by means of language.

When you need to express yourself in any particular language you need to know that language very well. If you want to express yourself in English then you can do that only by learning the language very well. You can use the language as you wish; you can express your love, you can express anxiety and also express your anger. The better you are skilled in the language the best you convey your emotions.
