People can’t see you when you’re speaking on the phone, but they can hear you. So, the way you speak is especially important. In fact, researchers have found that 80% of communication over the phone is through your tone（语气）of voice; and only 20% is from the words you use. Here are our top tips on how to speak over the phone.

1.Facial Expressions

Your facial expressions can influence your voice. For example, if you  smile, your voice will sound warm and friendly, just the opposite, if you have an angry look on your face, it can make you sound unpleasant.

2.Volume（音量）

If you speak too loudly, you could sound angry. And if you speak too softly, it’ll be difficult to hear you. So, speak loudly enough to be heard clearly, but not so loud that you’re shouting.

3.Pace

The pace of your voice is how quickly you speak. And this can show how you feel. For example, an angry person might speak faster than normal. Or a downhearted person might speak very slowly. Try speaking a little more slowly than normal. This will make you sound confident, and it’ll make it easier for the other person to understand you.

4.Gestures（手势）

Gesturing can influence the tone of your voice. When you gesture, you bring more air into the lungs, which can make your voice sound warmer. Gestures are also useful to help you stress the right words or even find the words you need. The best thing about gesturing during a phone call is that no one can see what you’re doing, so you can gesture as wildly as you like!

5.Movement

If you’re feeling nervous, stand up and move around. It will reduce the nervousness in your body and help your voice to sound more confident.

6. Pauses（停顿）

Using pauses every now and then can help you to slow down. This will make you sound more confident and in control. Also, if you pause after giving some new information, it’ll give the other person time to understand it. At the same time, listen to how the other person uses pauses. They could tell you something about the speaker’s feeling. For example, when a speaker is really angry, he might use pauses and say, “I... am... so... angry...”
