Orci and Kurtzman have openly admitted that they just fell in love with the idea of Bumblebee using radio clips as a means of communication, and decreed that all Bee's henceforth shall never communicate via conventional means. In order to give an explanation for this, they had Sam tell Mikaela that Bee was "playing it up" in ROTF, and apparently is still doing so in DOTM.
Even TFP Bee speaks in beeps. They probably wanted him to speak in radio clips too, but the right clips every single episode was probably too much work. And then there's copyrights issues.
