I'm reading a book out loud and it sometimes uses "f." and other times "ff." during references like: "(Harding, 274f.)" and other times there would be an "ff."

I've learned that that is an abbreviation from the Latin "folio" meaning pages that follow. And "f." means specifically a given section or chapter or what have you. And "ff." is less specific, meaning any number of pages that follow. Also, they are no longer recommended. Exact page number ranges should be used instead.

I would like to differentiate between the two in the audio format. Do you know of any way of pronouncing the difference? If there is no difference I'll just say the letter names instead of folio.
