Scientists have discovered why we often raise our voices during video calls: as video quality deteriorates, we speak louder and alter our gestures in an attempt to compensate.
Previous research had shown that when we cannot hear someone well because of noise, we speak louder, while the team’s recent work had shown that when a video call is not very clear, people make their gestures more noticeable.
The results showed communication was an integrated system of visual and auditory signals that work together to convey meaning. To compensate for poorer video quality, people exaggerate their gestures and speak louder in order to help their partner grasp their meaning.
近期，科學家們發現了為什麼我們經常在視訊電話中提高聲音的原因：隨著影片畫質的下降，我們會越來越大聲說話，並做出各種手勢，以試圖彌補構通的不足。
過去的研究曾指出，當我們因為噪音而無法清楚聽到電話那頭的聲音時，我們會提高音量大聲說話，而新的研究則證明，當視訊通話不是很清晰時，人們的手勢會更加明顯。
研究結果指出，溝通其實是視覺和聽覺信號的集合系統，尤其是口語表達，它們要共同作用以傳達意義。為了彌補較差的影片品質，人們會“誇大”他們的手勢形式並大聲說話，以幫助他們的談話對象辨別內容。
Attempt是嘗試的名詞，那in an attempt to意思就等於try to，通常是指是做了另外一件事，來達成想要的成果。
例句：
They closed the road in an attempt (= to try to) to reduce traffic in the city.
他們封閉了道路，試圖減少城裡的交通流量。
