When I was in junior high and high school I though I was going deaf, because I couldn't hear the person right next to me sitting on the gym bleachers. It turns out I have an auditory processing disorder. My brain can't keep up with what the ears are sending it, so it makes up words to try to keep pace.
I learned to look at people's lips when they speak and I didn't use the phone much. A deaf man I got acquainted with in college introduced me to text relay after I bought a TTY to communicate with him (and new deaf acquaintances at church). I used it for a while and then discovered that I could say a lot more using e-mail. Since I found relay to be a little slow and since I didn't call anybody except family, most of whose voices did not give me any problems, I stopped using relay and relied on e-mail and telephone amplifiers for 10 years.
Then, I started giving care to a senior citizen who requires many calls to docs, nurses, therapists, pharmacists, etc. Out came the TTY.
Finally, a new deaf friend called me via video relay. Well, that was interesting, because I had to play the part of a hearing individual and listen to a female relay agent. The FCC does not allow video relay to call TTY users through text relay. My deaf friend has gotten rid of his TTY so I can't call him up on the text telephone. Text relay calls for my senior patient were taking forever, so I got in touch with a couple of Video Relay Services (one for a TV set top video phone and one for a wireless video phone).
Thankfully, the VRS that installed the set top box allows me to hear the other party when I make a voice carry over call. However, I'm not sure if the VRS who sold me the wireless video phone will do the same thing, since that VP hasn't arrived, yet. Hmmm. . . .
Anyway, I'm finding the interpreters easier to understand since running through the dictionary of Rocket Sign Language. I'm changing a lot of my ten-year-old (and wrong) signs after seeing them demonstrated in video. In fact, sometimes I don't even use VCO (voice carry over), now, if my call is a short one.
I know it's cliche, but "Thanks Rocket Sign Language!" <huge grin>
