Oral expression

Within the field of human communication, there is no doubt that oral expression is and has always been of great importance to individuals. The survival of this form of communication over others shows that it is then one of the most important and useful human capacities for coexistence in society. While throughout history, human beings have always had the possibility of expressing themselves orally, the same cannot be said of other forms and technologies of communication that have been in existence for a relatively short time in comparison.

If we seek to define the notion of oral expression in descriptive terms, we must say that it is the ability developed by man to establish concepts, ideas and terms with specific meanings. Here, the oral expression of the human being differs from the oral communication of animals that, although it is carried out with objectives and desires, it is not ordered, conscious or full of specific meanings. Oral expression is what allows the human being to get in touch and establish connections with his peers, starting from it then the opportunity to establish objectives, goals and projects in common.

On the other hand, the idea of ​​oral expression is also related to the ability of certain individuals to reach certain audiences through the word. This is when daily oral expression ceases to be such to become a persuasive discursive structure in pursuit of achieving specific and clearly determined objectives. Situations such as exhibitions, debates, meetings, classes, sermons, among others are those in which certain people must have good oral expression skills in order to bring the appropriate message closer to the recipients.

Strategies and key factors in oral expression

In this sense, numerous exposure techniques have been developed in recent times that allow the individual to catch the public with their speeches and persuade them in terms of ideas.


The voice is the sound that comes out once the air is expelled from the lungs and when it leaves the larynx it causes the vocal cords to vibrate. The voice is important at the instances of oral expression because the auditory image always impacts any audience. Undoubtedly through the voice it is possible to transmit feelings and attitudes.


The posture is the relation of the positions that involve all the joints of our body and the correlation between the extremities with the trunk and vice versa. Putting it in simpler terms, the posture is the position of our body with respect to the surrounding space and the relationship of the person with it. It should be noted that the posture is also associated with cultural, professional, hereditary factors, habits, among others.

So, due to all the implications that the position can have, it is important that the speaker establish through it closeness with his audience or interlocutor. It is always advisable to avoid body rigidity and, on the contrary, to exhibit serenity and dynamism through the posture of the body.


The diction consists of the way of using the words of a language to form sentences, meanwhile, it will be considered as good diction when the use of words and their combination is correct and satisfactory with respect to the language in question. For example, the speaker must have a good command of the language because otherwise it will be difficult for him to express himself orally and make himself understood. Meanwhile, within this good handling, the correct pronunciation of the words is included, an issue that is undoubtedly essential to understand the message.


Fluency, on the other hand, is the ability of an individual to express themselves correctly and naturally, either in their mother tongue or also with their second language, if available. In other words, fluency is the ability to speak continuously and this is obviously functional and essential for oral expression to be effective.

volume and rhythm

It will be important to manage the volume and rhythm in oral expression since they are key when it comes to correctly transmitting a message. The intensity of the voice and the conservation of harmony and correct accentuation.

Clarity and coherence

Both are also relevant conditions because they positively help to express ourselves precisely and following logic. As has been proven, when there is neither clarity nor coherence, the messages are not convincing, they do not fulfill their purpose and of course that will affect communication.


Maintaining constant eye contact with the public will be essential for the audience to feel involved. The gaze is the most important of all non-verbal elements and one of the most communicates things. People often feel uncomfortable when they have a person on the other side who does not look them in the eye, this tends to generate mistrust and will undoubtedly affect the effective delivery of the message.
