Even more: speech in the native language is processed differently than non-native languages.

I was a proband in an fMRI study that played German and Polish fricatives (s and sh sounds) and measured the responses of different parts of the brain: https://elib.uni-stuttgart.de/handle/11682/2612

When a native German speaker listens to German fricatives, the same parts of the brain flare up as when a native Polish speaker listens to Polish fricatives.

But when the other language is played, different parts of the brain get active.
