Spoken communication is more powerful than writen communication. To what extent do you agree or disagree?
Some people believe that the power of verbal forms of communication outstrips that of their written counterparts. Personally, I think there is little to disagree with in this observation.
Spoken words carry more weight than written ones for several reasons, the most important of which are related to facial expressions and emotions. These could range from smiling with one’s eyes, which indicates a genuine smile and the genuineness of the message, to only smilling with one’s mouth, which can be perceived as a fake smile, and raising one’s eyebrows, which show disapproval or surprise, while he is enunciating a word. Of course, one might argue that a writer can simply add some extra adverbs to illustrate how a person feels more accurately, but we all too often find ourselves in loss of words when it comes to describing humans’ feelings.
Besides this, I note the fact that one’s way of speaking also affects how his message is perceived. Take, for example, a speech dellivered by a confident speaker who, at the same time, possesses clear pronunciation, a deep voice and a good pace of speech. What he hopes to deliver surely gets through more effectively than handing out to the same audience the transcript of what he says. This can clearly be seen in the way politicians often choose press conferences, and public speeches to best connect and persuade voters over any written forms of communication
In conclusion, the power of written communication seems to pale in comparison with that of spoken words. I take this view on account of the fact that the latter consists of many powerful elements such as facial expressions, emotions and ways of speaking, all of which are hardly ever successfully portrayed in any written texts.
