Which delivery mode is most often used for ceremonies, paid lectures, and commencement addresses?

The delivery mode most often used for ceremonies, paid lectures, and commencement addresses is memorized delivery. This is because speakers at these events typically prepare their speeches in advance, ensuring they can present their messages with clarity and confidence. With the memorized approach, a speaker can maintain eye contact and engage the audience effectively while delivering polished and practiced content.

Additionally, memorization allows for a smoother transition between points and can enhance the speaker's overall presence on stage. In contexts like commencement addresses, where the content is often significant and intended to be memorable, being able to deliver the speech flawlessly without relying on notes can create a more impactful experience for the audience.
