The code SOS is normally only used in text transmission; for voice communication, mayday is used. The sequence is normally transmitted run together without any letter spacing in between, so it is technically a single unique code rather than a series of three letters.
From the letters represented by the signal, chosen as a sequence that is easy to recall and transmit (· · · — — — · · ·); it is not, as is commonly believed, an abbreviation for "save our souls", "save our ship" or any other phrase.
