Orca

Orca is a free and open-source, flexible, extensible screen reader from the GNOME project for individuals who are blind or visually impaired. Using various combinations of speech synthesis and braille, Orca helps provide access to applications and toolkits that support AT-SPI (e.g., the GNOME desktop, Mozilla Firefox/Thunderbird, OpenOffice.org/LibreOffice and GTK, Qt and Java Swing/SWT applications). 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, and the UK vision impairment company Dolphin Computer Access. As of GNOME 2.16, Orca is the default screen reader of the GNOME platform, replacing Gnopernicus. As a result, Orca follows the GNOME stable release cycles of approximately six-months. Orca is provided by default on a number of operating system distributions, including Solaris, Fedora, openSUSE and Ubuntu. History 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 Marc Mulcahy, a blind programmer who worked for Sun Microsystems. When Mulcahy left Sun Microsystems and ventured out to start his own company, the Accessibility Program Office took his work, continued with it and released the first official version on September 3, 2006. 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. On September 7, 2011, Igalia, a company specialized in Free Software, hired Joanmarie Diggs and is supporting her work in Orca.
