Aonuma further details Zelda: BotW's voice acting, talks sci-fi elements

Coming from a Polygon interview with Eiji Aonuma...

On voice acting

"It’s really difficult to leave an impression on players with just text. It’s not that I made everything voiced. But I have these moments where I want to leave impressions on users. I add voice there. If Link said something the user doesn’t agree with, that relationship between the user and Link would be lost. That’s why I chose not to go with that."

On the sci-fi elements

"There is a little bit of a sci-fi element to it. Link basically adventures through a ruined world. I wanted to add technology as the opposite side of that. I thought it would be interesting for Link to use technology to explore through this wild and ruined world. I figured that would add another layer to the game."

Mr. Aonuma also teased a bit of story by saying that the technology at the heart of Breath of the Wild very well may have played a part in the world being "corrupted."
