Communicating by voice alone has its drawbacks, though.
但是，光凭声音沟通是有缺点的。
For example, I can't use hand gestures to clarify what I mean.
比如，我现在无法用手势来表达自己。
And, as it turns out, that makes a big difference.
这说明手势对沟通很重要。
Researchers at the University of Otago in New Zealand wanted to know how much a relevant hand gesture helps to communicate an idea.

They had volunteers watch video clips of a woman saying different simple phrases, such as “the square box,” or “peel the banana.”
志愿者被要求观看视频短片，短片中有个女人在说各种简单短语，比如，“方盒子”、“剥香蕉”。
In some, she simply said the phrase without moving her hands.
