Since your instructor is asking you to find peer-review articles, you need to go to a general database such as OneSearch , and enter the topic idea you have or keywords related to your topic in the search boxes. Once you get the results of your search, look to the left side bar: choose and click the "Limit To" checkbox for "Scholarly (Peer review) Journals."
You may want to look through the list: A-Z Databases and get subject ideas from the areas of health sciences, social justice, environment, etc. Many of the databases focus in topic areas that are helpful for researching speeches--like Criminal behavior, Environmental studies, Social and Gender issues.
