Responding to the OP but Ambrosia, I believe you have the most complete suggestion. The teachers will not always be looking at you and if you manage to learn a minute amount of lipreading you will still have trouble (as she said). You can learn it. But even the best lipreaders have problems. What if your instructor has a beard and/or mustache?Actually I think there's more people that grew up with hearing loss and wear hearing aids, speak, and some sign, than there are Deaf or late deafened.
To the OP...I'm kind of lost about the point of your thread. Are you asking us something?? I lost my hearing in my 20's, I've never worked on my speech reading skills, I think there are websites out there with exercises to do to improve them. I don't know, I'm pretty good at it, I guess it came more naturally?? I do almost as well understanding someone just using speech reading as do without my hearing aids, f it's someone I'm familiar with.
I wouldn't rely on speech reading at school.....I don't know about you but I need to pretty close for that to work, and since when does a teacher look right at you the whole time, they look around, they look down at their books/papers, turn around etc etc. Maybe you could get accomadations, CART whatever that is, or notetakers. DO they have that kind of thing available in Singapore?
I'd look into a backup for it. I personally don't like SEE because it becomes very tedious since suffix and prefixes are used as well as every article (a, the, etc.). I learned it and would likely still remember it but it's still just a partial fix to the problem you have. SEE entails signing end of words like "ing," "ed," etc. It may be more of what you're used to (sorry, Hochi, but this guy needs something fast) and it takes a while to learn.
Another "simply ask" route. In this economy it may not be feasible can you have someone type (like a court-typist) type what's being said and you would see it on a monitor. That's how I got through one legal deposition. The problem ... six years later when called into another and this was supposed too be the set up, I got there prepared for this method and they could not provide it - too expensive. I had to wing it on lipreading. BUT I could slow down the questions, you will not be able to.
Wait and look here for additional options here and ASK please at your school. In the meantime, I'd get crackin' on watching people and learning lipreading understanding it's a partial supplement not an answer.
Best of luck and do not give up, please. Your youth gives you the ability to absorb whatever you do choose more rapidly.
