Answer:
Advantages:
1.) It allows a blind person to use the computer
2.) It allows a blind person to create a document using a word processor like MS Word
3.) With the help of a screen reader, blind musicians now use audio editing software to record, edit and save their songs for example
Disadvantages:
1.) Because visually impaired people only listen to a screen reader reading the text displayed on the screen, they don’t usually have the chance to know the correct spelling of a certain word especially when it’s not that common like medical terms etc. Sure they can make a screen reader to read character by character after they hear a word that they don’t know the spelling but I find it very time-consuming.
2.) Screen readers use a computer sounding voice and some people find this very boring. Some companies are doing their best to create speech synthesizers that can mimic how humans read a sentence; like the proper intonation, but so far I would say that even we see some big improvements for the past years, they are still far from achieving their goals.
Hope this helped!
