Dictation software employing speech recognition technology allows voice commands to be translated to text or computer input.
Screen readers have built-in text-to-speech synthesizers that translate web elements and their contents into synthetic speech. Technology has empowered the blind and visually impaired to access online content using a wide range of assistive technologies. The only barrier that stands before them now is inaccessible content lacking support for assistive technology. Innovative solutions based on text to speech synthesis, optical character recognition, and speech recognition have empowered the visually impaired to navigate the digital landscape and enjoy the internet experience similar to people with sight.
