Final answer:
Oral and written communication differ in delivery and audience engagement, with oral communication requiring vocal techniques and visual aids, while written communication uses structured textual elements.
Step-by-step explanation:
One way in which oral and written communication are different is in their delivery and reception by audiences. Written communication often follows a structured format with elements like headings, boldface, and white space to help the reader navigate the text.
Oral communication, on the other hand, relies on the speaker's ability to engage an audience through vocal techniques such as inflection, gestures, and tone, as well as supporting materials like visual and audio aids to enhance understanding and retention. While a script for speech may share some structure with written texts, it must be adapted to be heard and understood in the moment, necessitating a focus on phrasing, stress, and clear pronunciation to achieve oral fluency.
