 Welcome to Orca

Orca is a free, open source, flexible, and extensible screen reader that provides access to the graphical desktop via user-customizable combinations of speech, braille, and/or magnification.

Orca works with applications and toolkits that support the assistive technology service provider interface (AT-SPI), which is the primary assistive technology infrastructure for Linux and Solaris. Applications and toolkits supporting the AT-SPI include the GNOME Gtk+ toolkit, the Java platform's Swing toolkit, OpenOffice, Gecko, and WebKitGtk. AT-SPI support for the KDE Qt toolkit is being pursued.
