Suggestions: Think of your voice as a roller coaster ride for your listeners. Are you creating a flat, boring ride? Try to make your roller coaster ride enjoyable for your particular audience; add some vocal drops, some inclines, and vary your speed. Vary your inflections and emphasize key words as well.
Also, record your voice in private. In fact, re-read this section in your normal voice and play it back. If you have never recorded yourself before, you'll be surprised by what you hear!
你是一只活力吸血鬼吗？
你也许热衷于分享故事和观点，但是，如果你没有支撑整个谈话的活力，人们会觉得很难再听你讲下去。谈话时缺少活力和感情会比其它坏习惯更快的毁了你们的谈话。好的交流是生动的；谈话者之间充满了活力。如果你不能不断加强这些活力，那么活力很可以会慢慢流失。
建议：把你的声音想象成是在让你的听众乘坐一趟过山车。你是否正在形成一次单调，无聊的旅程？试着为你这些特别的观众创造一次愉快的过山车旅程；增加一些语调的升降，变化语速。也可以改变声调强调关键词。
同时，私下里录下自己的声音。用你正常的声音再读一次这部分然后重播。如果你以前从没有录过自己的声音，所听到的将会让你大吃一惊！
