There are a variety of synonyms that can be used to replace the word "speech-maker." One option is "orator," which refers to a skilled public speaker who delivers speeches with eloquence and persuasion. Another possibility is "rhetorician," which emphasizes the art and study of discourse and persuasion. "Speaker," "lecturer," and "debater" are also viable alternatives. A more casual term might be "talker," but this generally implies less formality and expertise. Ultimately, the best synonym will depend on the context and tone of the speech being given, whether it be a political rally, academic lecture, or stirring eulogy.
