Intonation

Intonation is music of language. When your task is to envelop the auditory with your speech and attract their attention to your ideas, it is important to work with your body, gestures and voice as well. Flat speech is not able to impress even if you read some books about making speech and learn that a good funny story is to cause your success. No, make sure that you can speak correctly. The most successful speakers used to stress the words in a right way. It means that beforehand they take the pen and start stressing the syllables, words and sentences of their text. There is nothing shameful in it. Every person seems to learn something every day of his life. If you think that you can not speak properly or you do not achieve your goals with your words, try to train your voice, intonations and stresses while you are at home alone. Try different stresses and intonations in order to choose the best one. If it does not work out, mark the stresses with arrows and read them first, then repeat without prompting. Remember that every sentence is to have the main word or phrase in accordance with the content. Avoid the words which repeat each other (tautology) or have similar meaning. They draw attention and prevent understanding. So, it is important to train your intonation skills and build the correct sentences.
To develop intonation intuition, listen to other people, how they speak and where they make mistake. This exercise does not require much time and could be done even when you are busy with other things.
