People with visual impairments, including blindness most often use an assistive technology (AT) device called a Screen Reader. A screen reader is a software application that attempts to identify and interpret what is being displayed on the screen (or, more accurately, sent to standard output, whether a video monitor is present or not). This interpretation is then re-presented to the user with text-to-speech, sound icons, or a Braille output device. Screen readers may also be used by people with a learning disability. Screen readers are often used in combination with other AT for screen magnification. (Source Wikipedia

Non Visual Desktop Access (NVDA) – for Windows PC
NVDA is a free and open-source screen reader for the Windows operating system, enabling blind and vision impaired people to use their computers for no more cost than the computer and operating system itself. Started in April 2006, it has grown to become quite usable as a day-to-day screen reader, enabling the user to do most tasks they would need to. It is not as stable or as bug-free as some of the commercial screen readers, but since December 2006 the creator of NVDA has been able to use NVDA full-time as his primary screen reader, finally giving up his original commercial product.

Android Accessibility Suite (TalkBack) – Android phones
TalkBack was an accessibility service for Android that helped blind and visually impaired users to interact with their devices. It used spoken words, vibration and other audible feedback to allow the user to know what is happening on the screen allowing the user to better interact with their device. The service was initially a downloadable app but eventually was pre-installed on many Android devices. In 2017, it was replaced by Google with Android Accessibility Suite which comes pre-installed on many Android smartphones.
