There's nothing wrong with those. What you're watching are the original ocean dubbed episodes that were aired from 1996-98. Ocean group had different voices, cut a lot of the earlier filler, and added their own sound effects. Starting in '99, the dub switched to funimation's own voice actor group based in Texas. After the frieza saga, ocean group dubbed the international release of DBZ, while funimation continued to do it in the US. The international release, however, suffered from low budgets, was rushed, and many of the voice actors changed. A few years ago, funimation redubbed the original episodes ocean did, so you can always watch those if you want to hear the newer voices. With that said, many people, such as myself, prefer the original 53 ocean dubbed episodes over them. Just to note, the infamous "over 9000!" comes from the original ocean dubbed episodes.
