Think of it this way. Many developers need to learn the ins and outs of assistive technology to best identify how to incorporate accessibility into their software. I personally see no issue with that. Knowledge is for everyone.

Some people need information delivered in an auditory way to best absorb it, when they are driving it might be best to have the technology read the message or voice assistant do the work for them. Honestly learn it, you might find that there are places in your life where the skill is invaluable. Generally speaking if something is more widely used by the general populace then there is more incentive to make it more widely available. Exceptions do exist, something like wheelchairs or medicine will have individual costs that outweigh this benefit of encouraging society to increase the availability of these accommodations or tools.

I think it's great you want to learn. Go for it.

You would be doing us a service in fact. Ours is a small segment that is often dismissed as not immediatly profitable to support. The more using talkback the better.

Just use headphones in public whenever possible.

I've got kind of a unique experience with this, as when I was 17 I had the opportunity to learn braille and chose not to, then at 18 I went blind. Genuinely, I think people should learn adaptive things if they're interested, because you never know when you'll need them.

Not an issue. Audiobooks (first called talking books) were a blind thing back in the day. Now they're mainstream, and what does that mean? Tons more titles, tons sooner, for example. If people start using voice interfaces more it may make developers more interested in making applications and websites accessible.

In my opinion, Learning something in a proper way, shouldn't offend anyone. If you have interest, go learn everything or anything, learn how to use cane, learn how to navigate blindfolded, the sky is the limit.

More people need to learn to use screen readers. I think it would help them start to better understand the barriers they sometimes inadvertently put into the digital media, applications, and such that they build. Plus, you can provide better assistance/support to people you interact with that may happen to use a screen reader.

Additionally, it can be beneficial for if you ever need to make use of a screen reader yourself. Everyone has a high chance of experiencing vision loss at some point. May be due to aging, medical condition, injury, or some other cause. We can't pretend it will for certain never happen to us.

I learned to use NVDA, Narrator, JAWS, and VoiceOver back when I was internal tech support for a company. Recently, I got my eyes dilated at an eye appointment and it last for MUCH longer than usual.

Usually, by the time I get home I can see well enough to do some basic things on the computer. I'll have trouble typing, but be able to see larger icons, buttons, etc enough to do some tasks. This time, I got home and could not use my computer for a solid 2-3 hours. The screen was a blur of colors and no defined shapes.

There was a meeting I wanted to join because it was a celebratory one for an accomplishment I was part of, but I couldn't see the screen to interact with my chat application. So, I started Narrator using the keyboard shortcut, and was able to join the meeting and listen in. I could also join the chat. It made me appreciate the fact that I had that option available. Wasn't perfect since I don't know all the keyboard commands and such, but definitely better than being isolated from participating.

Edit to add: sorry my comment is so lengthy. Got so excited to comment on this.

I can garantee you that someone will be offended. I can also garantee you that it doesn't matter because someone is always offended. Learn what you want and don't let anyone tell you you shouldn't.

Go for it :)

Many people use audio reinforcement for one reason or another. 8% of the population is dyslexic, for example, and they also use the screenreader functions.

I teach people to use screenreaders (JAWS/ NVDA/ VoiceOver/ ChromeVox/ TalkBack), but I also try to stay abreast of screenreaders "just in case". Life is short, our bodies are fragile, and you can lose anything at any point.
It is much easier to learn these technologies (even just a little) when you don't *HAVE* to learn them. If your vision does fail at some point, you will be better off having played around with TalkBack now.

Learning a new technology should not be offensive for anybody; you are not passing yourself off as blind falsely in order to garner sympathy, for example. It also lets you help other people that you may encounter. For example, I have not encountered a single salesclerk at any of the cell-phone stores that knows anything about accessibility (iPhone or Droid). 26% of the adult population in the USA has a disability (assuming similar numbers for other countries; 5% of adults have significant vision loss. You WILL encounter people who have no idea that their phone can even do this, and learning these tools allows you to help people also.

It is definitely weird, eccentric, or odd.

I think the main thing is don’t use it and other stuff to fake blindness, and to lie and deceive people, but otherwise I don’t see anything wrong with it, no.

You're fine, why would anyone worry? You're not stopping anyone else using it. Do your thing, and stop apologising!
