It may be the mics or recording conditions (e.g. V.A. recording at home and sending the voice clip) or maybe a filter was used on the German ships to sound more... foreign?

Most newer lines have a different tonality, consider resupply lines for Nagato or Hiei. It could be any sort of thing, such as highpass compression instead of lowpass...
