What is a key component of effective delivery in public speaking?

Consistent body language is essential for effective delivery in public speaking because it enhances the speaker's message and helps establish a connection with the audience. When a speaker's body language aligns with their verbal communication, it reinforces their message and makes it more persuasive. Consistency in gestures, posture, and facial expressions helps convey confidence and engagement, which makes the audience more receptive to the speaker.

In contrast, using complex vocabulary can alienate the audience if they do not understand the terms being used, which can lead to confusion rather than clarity. Speaking rapidly can hinder comprehension and make it difficult for the audience to follow along, detracting from the overall effectiveness of the presentation. Lastly, reading from notes can create a barrier between the speaker and the audience, making the delivery feel less genuine and spontaneous, which is generally not conducive to effective communication.
