Do you think an old LP record with a 1967 speech by an author (criticizing the JFK ) Warren Report is copyrighted? I would love to use this audio in a documentary I am making….

I don’t want to use the whole, just a few snippets. I have heard that one can use up to 7 seconds of a copyrighted movie for purposes for “critique or review.” Are there any rules/laws/precedents about spoken word albums?
