Bethesda's open-world RPGs have become progressively smaller over the years (Skyrim being the exception), though this has resulted in more focused and interesting worlds. Fallout 4 will match the developer's previous title in land size, though it is splurging on another front -- dialogue. And not a little bit either.
A post from Bethesda's Twitter account last week declared that all the voice recording for Fallout 4 has been completed and from the sounds of things, was a rather massive endeavour compared to its previous works:

I'm all for more story and character... but I've never felt that these were Bethesda's weak points. The narratives have always been solid, what's often let games such as Oblivion down is the lack of variety in voices.
At some point you have to accept that recording (and paying) hundreds of people just to add some diversity is impractical, but hopefully the studio has done its best to reduce the aural sameness of its latest creation.
