News Articles and Built-in Screen Readers!

Hey Guys,
I have noticed something recently while reading articles on my iDevices. Some big name tech blogs and newspapers are including their own built -in screen readers. It stops your default voice over choice, and new voice takes over to read that specific article. For instance; I know that CNET articles do this.
While I truly do appreciate the effort some of these companies are taking. I find some of the voices excruciating. Very whiny and synthesized. Is their a way to keep these voices from taking over for my default selection, while reading that article.
