Transforming Noise

Ok, this may be something that has been discussed before, I have never personally seen it though. I was thinking alot about this earlier today, but in Beast Wars, they had to say a phrase, such as So and So Maximize, or Terrorize! But in the original series, they really didn't. Since Beast Wars is a continuation off of G1, did they seem to revert in technology over the years so that they had to say a phrase, or did they always have one in G1, was it that "transforming noise" that you heard before/as they were transforming? Is that even a slight possibility, or am I just crazy?
