You will find examples of footnotes for speeches in the Chicago Manual of Style Online - see link below.
The facts of publication, and other elements you need to include, will vary depending on where you sourced the recorded speech or the speech transcript from, and in each case you should follow the rules for the source document.
For example, below is a footnote and bibliography example for a speech transcript accessed from a chapter in an edited eBook (with no DOI).
John F. Kennedy, "Ask not what your country can do for you," January 20, 1961, in Chambers Classic Speeches, ed. Andrew Burnet (London: Chambers Harrap, 2006), Credo Reference Collection.
