Hi, we already have technologies like that. Are you looking for something like that for your lectures? They don't use keyboards. That takes forever, but a Court Reporter uses a Stenographer which makes it easy.
This is a technology called Communication Access Realtime Captioning (CART). It's a stenographer that is used like those in the court. Sometimes these people do work in court at other times!
The stenographer is hooked to a laptop. There's other ways, but usually is a laptop for college. They type how they hear words phonetically, then it's transferred to the laptop into English words. It's REALLY cool. They sit near you, but they aren't really like an interpreter because mostly they focus on hearing and typing. They are only a few seconds behind as they hear and type. There are a few times where words are messed up, but you usually find out what it is as you read along or ask the captioner to tell you or type it up for you. I really like it. I can write up notes sometimes at home or you can type them and highlight important passages. They print it out for you or they e-mail you the notes. You use it however you want. Usually, I had a notetaker because many professors vary in how fast they are speaking, etc, etc. Then I would take the notes of the notetaker and go through the notes to add more notes missed and highlight important stuff. Some notetakers really suck. It's not easy finding a really good one in the beginning when you miss part of the stuff. That's why it's important to read your books and the notes. It's like a backup.
I really liked it. You should ask your disability office in college to request it. Try one class and see how you like it. I didn't think it helped with College Algebra at all, so I went alone, listened and read my textbooks before class. That helps a lot to prepare you.
Oh, and I don't find reading straining or hard on the eyes. Even I had times where I wanted to look elsewhere besides interpreter or daydream like other kids. It happens usually for lack of sleep or real boredom. It's normal, don't worry. I think you can ask them to make it bigger for you if you need to. They usually use MSWord, so it's possible to change the size of the font. I have had 2 with old fashioned programs and even a really old laptop from like the 90's or something. I had one that was really rare. They have this thing where you hook it up and the person talks into a 'cup' which translate like speech-to-text. I find that one made a little more mistakes than other ones. It wasn't so bad, but I think it's not used so often as of yet.
