Emphasis is a technique used in communication to highlight important information or ideas. It can be achieved through various means, such as vocal stress, font styles, or visual elements. For example, in written text, using bold or italic fonts can draw attention to specific words or phrases, making them stand out to the reader. In speech, emphasis can be conveyed through tone, volume, or pacing. By altering these vocal elements, a speaker can signal to the audience which parts of their message are most significant. This helps ensure that key points are understood and remembered, enhancing overall communication effectiveness.
