You are right, the new voice makes och sound like, I don't know what here. Something between e and i. For some odd reason, because the Voice usually gets och right, for instance the sentence Han och hon sounds just as it should (I can't link you there since there isn't a discussion forum for that sentence yet).

The slow audio is OK, although hon doesn't sound quite perfect.

I was worried that it was just me. Swedish is hard enough without straining to hear the audio and wondering if it's my hearing going bad.

Most often it's just pronounced like o (å), but the k can be heard sometimes if people speak extra clearly or stress the word.

yes im noticing this. said seperately its sounds ock, as a sentence its just blends in

Just the way Swedish is. The K-sound is silent unless you emphasize the word.
