Pro tip for those who would want to read scientific papers on ArXIV with a screen reader. ArXIv usually offers “source” versions of their papers, usually written in LaTeX, which is much easier to deal with than PDF. You can retrieve the source by clicking the “other formats” link. On the page that opens, you can also change your default download format. If the file downloads without an extension (as it does for me), set the extension to .tar and extract it with any serious archive extraction tool (7Zip and WinRAR should both work.) If you don’t understand LaTeX (and if you’re reading papers on arXIV, you probably do), you can find some nice tutorials by Googling.
