You know you have to say it. Out loud. The sources of your information….
And it is good and proper that we DO give credit where credit is due as we are giving speeches that inform, inspire, persuade, instruct, and generally educate your audience. In all fairness, one of the real academic benefits of preparing a platform speech is the research you learn how to do. You garner information from a variety of sources, learn from it, process it, and integrate it into your own paper – a blend of your ideas and words with those you’ve learned along the way (which by the way totally shaped your ideas, you know!)
