There are several writers who post on r/fanfiction and aren't subscribed here, most of which post on AO3 or AlternativeHistory. ASOIAF is simply way more active there. These are complete fics sorted by length and I also fail to see a lack of fics longer than 60k.
My numbers are also strictly for the book category. For AUs, you can as well look in GoT, since all you need is the character tags. Doesn't make much of a difference if book-Ned or show-Ned lives; everything after that will be different anyway.
But sure, if you insist on limiting yourself to the archive with the smallest ASOIAF section, "life support" might fit.
Balabolka is free text-to-speech software. Can use the regular Microsoft voices; there are more for download, and voice pitch can be adjusted somewhat.
Natural Reader is a browser app with plenty of free voices and paid premium voices. Also has mp3 conversion.
(I flair this as Writing Help because TTS is useful for writers, too. I use it for proofreading.)
ReWriting A Song of Ice and Fire is ten chapters in and is updated every couple of weeks. The Long Night has fallen, Westeros is lost, and Jon dies only to be reborn again as himself. Literally, with memories and experiences included.
edit: oh, this post is a month old.
eh.
