This is a really interesting project but I think it's going to be seriously hard. You're going to need to parse meaning from a site, and that's not an easy thing to do. 

If you're focused on a few of the bigger sites then it might be easier. 

You almost want a middle layer that can parse meaning from a site into xml or something. 

Then I'd work on creating objects out of each kind of tag. The problem is that navigation may not be the same as you'd see when visiting a site. You're not really going to be moving left and right. It would be more like tab works. Next item kinda thing. And items wouldn't necessarily be in the same order as you see. Pull right/left classes for bootstrap etc would make layout different. 

I would maybe check if there are any libraries that can parse HTML into objects first and if not then start building on yourself. The telephony side will be easy. You'd use agi or something to navigate the object you create and tts to describe current position. The hard part will be parsing the HTML even though most HTML is broken :-)

Kind regards,

Matt Riddell
