How does a teleprompter assist speakers during presentations?

A teleprompter is designed specifically to display a scrolling script, allowing speakers to read their lines while maintaining eye contact with their audience. This functionality helps to enhance the delivery of their speech or presentation, as it reduces the need for speakers to memorize their script or look away to reference notes. The scrolling text is typically positioned at eye level, ensuring that speakers can engage with their audience while seamlessly following their script.

Other options do not provide the intended support for speakers in the way a teleprompter does. Visual aids in the form of images can enhance a presentation but do not assist with reading a script. Controlling lighting is important for visibility but is unrelated to the specific task of delivering a speech. Similarly, amplifying a speaker's voice is crucial for ensuring the audience can hear, but it does not aid in the organized delivery of content. Therefore, the primary role of the teleprompter aligns solely with displaying a scrolling script, making it an essential tool for effective presentations.
