I selected All EBSCO Interpersonal Communication. Click on 'Search Options' and limit by Full Text. I did a quick search: introducing speaker

I found a few articles that may be of use, including one 'Introducing a Speaker'.  It is often helpful to try other words to help you find additional materials.  Check the words used in the article you are reading for other possible search strategies.
