Gather all of the pertinent information on the personal speaker and their speech. For personal communication citation, you need to include the speakers name, the title of the speech (if it had one) and the date that it occurred.
Put the personal speaker information in parenthesis after the cited information within the body of the paper, such as "(King, S., personal communication, January 1, 2000)." If the speech had a title, it can be included after the speakers name and before "personal communication."
Do not place the personal speaker citation in the reference list. Because it is an unpublished work, there is nothing that can be physically looked up to verify the information.
