A speech prompter also called a teleprompter in TV studios is designed for corporate conferences and events where a speaker is addressing the audience.

A speech prompter enables a presenter to deliver a speech electronically without having to read from a script. 

When erected, the prompting system resembles a mic stand with a piece of glass attached to the top of it.

From the audience's side, the high-quality prompter glass is transparent, giving the impression that the presenter is speaking extemporaneously and professionally without any assistance.

From the presenter's side, the glass displays scrolling content of the pre-prepared speech from the prompter LCD monitor at the base of the stand.
