it might be nicer to have them read through rather than having to read them yourself.
First of all, thanks for the offer.
I think that the options greatly differs from person to person.
I read even when I commute - either bitcointalk, either news, either a book - on my phone. I find easier and faster to read myself. This way I can also skip the parts I find irrelevant (for me). So no, another text-to-speech (or whatever form) would not help me.
I even used to ask for the opposite: here and there some projects publish audio files with meetings, what is decided to do next, how the project is going and so on. Most of the time I don't get to listen to them, because I would be interested in some 10% of it and don't afford to listen 30-60 minutes for that. I asked a couple of times for transcripts, then I just gave up.
Nowadays, especially for English, people can have text to speech if they want it, on their phone, on their Windows (I think).. At least I seem to bump over that more than necessary
TL;DR; For me it's not an useful feature/effort; thanks though.
