The American Speech Music
One of the main differences between the way an Amercian talks and the way the rest of the world talks is that we don't really move our lips. So, when an American says, "Read my lips!" what does he really mean? We create most of our sounds in the throat, using our tongue very actively. If you hold your fingers over your lips or clench your jaws when you practice speaking American English, you will find yourself much closer to native-sounding speech than if you try to pronounce every... single... sound... very... carefully.
Intonation, or speech music, is the sound that you hear when a conversation is too far away to be clearly audible but close enough for you to tell the nationality of the speakers. The American intonation dictates liaisons and pronunciation, and it indicates mood and meaning. Without intonation, your speech would be flat, mechanical, and very confusing for your listener. What is the Amercian intonation pattern? How is it different from other languages?

American intonation dos and don'ts
Do not speak word by word! Bob... is... on... the... phone. If you speak word by word, as many people who learned "printed" English do, you'll end up sounding mechanical and foreign. You may have noticed the same thing happens in your own language: When someone reads a speech, even a native speaker, it sounds stiff and stilted, quite different from a normal conversational tone.
Connect words to form sound groups.
This is where you're going to start doing something completely different than what you have done in your previous English studies. This part is the most difficult for many people because it goes against everything they've been taught. Instead of thinking of each word as a unit, think of sound units. These sound units may or may not correspond to a word written on a page. Native speakers don't say Bob is on the phone, but say [bäbizän the foun].
