Orca is a LibreOffice and GTK+, Qt and Java Swing/SWT applications).

The development of Orca was started by the Accessibility Program Office (APO) of Sun Microsystems, Inc. (now Oracle) with contributions from many community members. The original idea and the first working prototype for Orca was started in May 2004 by Mark Mulcahy, a blind programmer who worked for Sun Microsystems. When Mark left Sun Microsystems and ventured out to start his own company, the Accessibility Program Office took Mark's work, continued with it and released the first official version on September 3, 2006.[3][4][5] When Oracle acquired Sun Microsystems in 2010 they cut developer jobs of full-time developers working on GNOME accessibility components, including Orca main maintainer Willie Walker. Since then, Orca is run by volunteers, led by Joanmarie Diggs.[6][7] In September 7, 2011, Igalia, a company specialized in Free Software, hired Joanmarie Diggs and is supporting her work in Orca.[8]

The name Orca, which is another term for a killer whale, is a nod to the long-standing tradition of naming screen readers after aquatic creatures, including the Assistive Technology product on Windows called JAWS (which stands for Job Access With Speech), the early DOS screen reader called Flipper,[9] and the UK vision impairment company Dolphin Computer Access.[10]

As of GNOME 2.16, Orca is the default screen reader of the GNOME platform, replacing Gnopernicus.[11] As a result, Orca follows the GNOME stable release cycles of approximately six-months.[12] Orca is provided by default on a number of operating system distributions, including Solaris,[13] Fedora,[14] openSUSE[15] and Ubuntu.[16]

Linux Screen Reader (LSR) was an alternative screen reader to Orca led by IBM and started in 2006. However, it was ceased the following year because IBM focused their resources in other projects.[17]
