I am sorry to hear of the difficulties you've had with your voice. My question to you is one of curiosity. Why are you here? This appears to be your first post and I'm the nice one here so I'll just let you know before the others jump on you. You put a bad foot forward buddy....
now, with that said I'm also going to assume you are in the medical field or just know medical terms really well. I was a pre-med student many years ago but dropped out after my mother died to tend to my family among other things and the average person doesn't know or are not familiar with the terms you've used. You appear from your post to be of above average intelligence but are lacking in one area but what that is I'm sure the others will point out to you.
For one using the word garbled was rather insulting but that is besides the besides the point.
I do understand your fusteration in regards to being unable to communicate with the Deaf woman you came in contact with but it is not impossible to communicate with "one of us" as you put it. You can use the pen/paper route if you cannot use your voice. Not all of us use ASL so this lady may not even know ASL and that is another assumption that you've made about us.
As for Deaf culture why we have our culture and others don't as far as I'm concerned is the fact that we have our own language. Our own unique language with it's own unique syntax and structure although Deaf Culture is more than just the language. It's a why of life at least for me.
Maybe you didn't mean to come off as you did and I'm willing to keep an open mind and with that said, welcome to alldeaf................not.
Trust me, my speech is garbled. Honestly, I was just plain frustrated because no-one (hearing, deaf, etc.)can understand me, apparently severely so, because to people with normal hearing, it's undetectable unless I'm in an absolutely quiet room. I should bring my pen/paper more often, it's just that I often don't have anymore space in my jacket pockets.
I was just looking for advice (and my comment was just a factual observation, no insults intended), because there's almost no online support for those with vocal issues, so I said to myself "well, deaf people also have trouble communicating with those that are hearing, so maybe I can get some ideas to help me out until I get my larynx fixed."
Also, I'm an immunology BSc student, and I hope to go to medical or dental school after I graduate. I also hang out with a lot of doctors and other health professionals; my mom is a nurse.
I have an extremely frustrating life, because I can't express myself. You can do that.
Oh, and it's extremely insulting to call my problem fictional. Extremely.
