Not every acronym is pronounced by pronouncing each letter, e.g.,
radar is an acronym for "radio detecting and ranging" and laser is an
acronym for "light amplification by stimulated emission of radiation".
While SC 3.1.3 may assist text-to-speech systems in pronouncing the
abbreviation, the goal of the success criterion is to be sure that the
meaning is available.
