Hope it works for every website. I've tried it on a couple of sites which did not want to zoom and it worked so try it out!
If not, I think that Dolphin Browser also has an option for 'force zooming'.
If you are reading pdfs on a Mac you could try Skim. It has a reading bar which by default focuses on one line. You can also change the colour in the menu item: Skim>Preferences>Display.
You can also "invert" the bar so that the rest of the text is hidden.
As far as I know you need to drag the bar from one line to the next with the mouse.
There is a quick ...

I have a reasonable understanding of how screen reader software processes HTML semantics. To my knowledge the majority of SR software does nothing with the cite attribute.
The JAWS screen reader does announce the cite attribute value when it is ...

This application converts voice to text for the voices on both side of an outgoing cell phone call. Its transciption quality seems pretty good; I think it is using a Google voice-to-text conversion service ...
Google Sheets has a page outlining its Section 508 Compliance on the accessibility page. It says it is supported "with exceptions". I couldn't find any information on Section 508 for Microsoft Excel Online specifically, but found a page about general accessibilty.

The built-in Messages.app has support for AppleScript, and includes an example script that will use the OS speech system to notify you about events (message received, new chat invitation etc) - a little editing (to comment out unneeded parts and add message speaking) should do the trick.
In fact, it seems like the default "Speak Events" script does ...
