(often shortened to Oral Interp, Oratorical Interp, Oratorical, or abbreviated to OI) is an event in competitive high school forensics. Similar to Original Oratory
, Oratorical differs in that the speeches performed must be published material, not original material. The speeches given are speeches originally delivered in a public forum. Examples include the Inaugural Address of John F. Kennedy
, "I Have a Dream" by Martin Luther King
, and any college graduation speech. In a typical round of competition, five to seven competitors will declaim speeches before a judge. After the round, the judge will rank them from best to worst, and assign each competitor a score, which will be used to break ties when the tournament is tabulated.
Like Duet Acting, Oratorical is not a National Forensic League-sanctioned event. It is practiced by other speech leagues, including the OHSSL and California High School Speech Association
