I think it's more like this:
Don't forget the empty toadstool also... if at Battle Stations, you might get a third one. The "voices" you hear are basically time-triggered, so there are instances where a voice will repeat because the game allows 3 seconds (as an example) for an "event", but the ogg file has been edited or changed, and is only 1.25 seconds long, you will then get two or sometimes 3 voice repeats - unless something "more important" interrupts. "We're taking damage sir!" "We have heavy flooding sir!!!" CapnScurvy "padded" some of the voice files in FotRSU with muted audio to make the files longer in length, and that did help with reducing some of the shorter voice repeats. There are more that need that treatment though.
