There are four main methods of speech delivery: 1. Impromptu speeches which require short preparation time and focus on a single main point. 2. Manuscript speeches which are read from a prepared text but are difficult to change and less engaging. 3. Memorized speeches which allow for a skilled, natural delivery but require extensive preparation. 4. Extemporaneous speeches which use note cards for outlines to allow for a more spontaneous yet still prepared delivery. Effective speech delivery requires practicing techniques like emphasis, pauses, eye contact and facial expressions to engage the audience regardless of which method is used.
