Q: How to change the "defualt language" on Voice Over?

I am a bit behind on the hardware (iPad 1) but only recently discovered the accessability options such as VoiceOver. When I gave the language rotors a go, after going around once it said "default language; Australian English." I do not see any point in this, because:

1. This iPad was not bought in Australia nor New Zealand

2. I live in New Zealand (although I can grudgingly understand NZ English doesn't have its own option)

3. Everything is set around UK English.

I've been searching Google and Apple support threads about this, but it seems only I am troubled with this. Does anyone know how to change that?

If I spoke honestly, I just don't like the voice and would rather not have it!
