Welcome to the series of spoken tutorials on the Orca Screen reader. Orca is a Free and Open source screen reader that works in GNU/Linux operating system. It is an integral part of the gnome desktop.
A project initiated and funded by the accessibility department of Sun Micro Systems (now Oracle), it is the most efficient and powerful accessibility tool for totally blind and low vision computer users in the FOSS arena.
Since Sun is no longer involved with the project, it is now a community based project and gets its resources from many government and private organizations including research institutes.
With the use of Orca, a totally blind person can work on the desktop with no sighted assistance.
With the output in synthetic voice, all activities can be independently performed.
These activities include word processing, working with spreadsheets, surfing the internet, working with emails, chatting and also main-stream programming.
What this talking software does is that it gives audio feedback through a speech synthesizer by following the focus and reading any textual information and informing the user about any widget in and around the focus.
About these spoken tutorials
These set of spoken tutorials will be a comprehensive documentation on Orca for a visually disabled person.
The tutorials will start from absolute basics and then go on to explain specific computing activities which a user can perform using this screen reader.
