engages in more thought before she says something
Step-by-step explanation:
Public speaking is described as a phenomenon of giving speech "face-to-face" to the different live audience.

Fundamentally, public speaking was represented as a part of the "art of persuasion".
Public speaking is often considered as similar to "everyday conversation" as an individual requires to organize his or her thoughts logically or analytically, he or she has to tailor a specific message to his or her audience, he or she needs to tell a story for greatest impact and he or she has to adapt to certain feedback.
