I prefer Wii Fit Trainer's British accent.

I've listened to voice clips from both versions of WFT, and I think that the PAL version of their voice is much more enjoyable. They sound so much more enthusiastic about fitness than the American trainers, who sound like they're about ready to fall asleep. Also, the American trainers speak more slowly than the British trainers. Do you think that says something about America?

The american trainers actually have a more centered feel to it. I heard that during localization, Nintendo decided to model the trainers' speech after a middle aged, vegan, Buddhist for the NTSC version. Later, that sensibility didn't test well with the European market so instead they modeled character's demeanor after an orthodox christian for the PAL version.

For reference here is a video of the audio for both Wii Fit Trainers in the PAL version
