Speechification is a rather uncommon term, and as such, it may be more practical to find more widely recognized synonyms. One of the most precise words that could replace speechification is oration, which refers to a formal speech or discourse. Other possible synonyms include declamation, address, sermon, talk, lecture, presentation, or communication. While all of these terms refer to forms of spoken expression, their usage may differ depending on the context and purpose of the speech. Ultimately, finding a fitting synonym depends on understanding the nuances of the word and selecting one that conveys the appropriate tone and meaning.
