As the term/software was not known to me I used a search engine:
Read&Write Gold is literacy software developed by Texthelp for either a PC or a Mac that can make documents, files, and websites more accessible on any platform or device.
From reading on-screen text aloud to researching and checking written work, Read&Write Gold makes everyday tasks easier. It is a great tool for people with dyslexia and other learning difficulties, anyone whose first language isn’t English, or for people that want to augment their writing skills
