I quite like the Soundwave voice, though it took me a bit to understand him, at first - wasn't sure which parts of the sound to focus on, but was fine after a bit. Makes me want to see if you did any audio versions of fics where Kosh speaks.
“They planned their campaigns just as you might make a splendid piece of harness. It looks very well; and answers very well; until it gets broken; and then you are done for. Now I made my campaigns of ropes. If anything went wrong, I tied a knot; and went on.” -- Arthur Wellesley, First Duke of Wellington
