ATK NOTE:The code for this project has been subsumed into other projects, most notably http://www.gnomefiles.org/app.php/GERvoice 'Accessibility' means enabling people with disabilities to participate in substantial life activities that include work and the use of services, products, and information. GNOME Accessibility is the suite of software services and support in GNOME that lets people with disabilities use all the functionality of the GNOME desktop.

Accerciser Accerciser is an interactive Python accessibility explorer for the GNOME desktop. It uses AT-SPI to inspect and control widgets, allowing you to check if an application is providing correct information to assistive technologies and automated test frameworks. Accerciser has a simple plugin framework which you can use to create custom views of accessibility information.

AllTray AllTray is software that allows users to dock any application into the system tray. You can dock (for example) Mozilla Thunderbird, Evolution, and even terminals. A highlight feature is that a click on the close button of an application will minimize it to the system tray. It works well with Gnome, KDE, XFCE 4, Fluxbox, and WindowMaker.

At-spi 'at-spi' is a part of the Gnome Accessibility Project. It provides a Service Provider Interface for the Assistive Technologies available on the GNOME platform, and a library against which applications can be linked.

Brltty BRLTTY is a daemon which provides access to the GNU/Linux console (text mode) for a blind person using a soft braille display. It drives the braille terminal and provides complete screen review functionality. The web site has a complete list of braille display models that are supported. Features include blinking cursor and capital letters, screen freezing for leisurely review, attribute displays and attribute underlining to locate highlighted text, hypertext links, intelligent cursor routing for easy cursor movement without moving your hands from the braille display, a cut and paste function, on-line help, and a modular design that lets you add drivers relatively easily.

CMUSphinx- PocketSphinx Sphinx is a speaker-independent large vocabulary continuous speech recognizer. It is also a collection of free and open source tools and resources that allows researchers and developers to build speech recognition systems. The packages that the CMU Sphinx Group is releasing are a set of reasonably mature, world-class speech components that provide a basic level of technology to anyone interested in creating speech-using applications without the once-prohibitive initial investment cost in research and development; the same components are open to peer review by all researchers in the field, and are used for linguistic research as well. PocketSphinx is CMU's fastest speech recognition system. It uses Hidden Markov Models (HMM) with semi-continuous output probability density functions (PDF). Even though it is not as accurate as Sphinx-3 or Sphinx-4, it runs at real time, and therefore it is a good choice for live applications. You can find further documentation about PocketSphinx in the release documentation, or at the online documentation.

CMUSphinx- Training Sphinx is a speaker-independent large vocabulary continuous speech recognizer. It is also a collection of free and open source tools and resources that allows researchers and developers to build speech recognition systems. The packages that the CMU Sphinx Group is releasing are a set of reasonably mature, world-class speech components that provide a basic level of technology to anyone interested in creating speech-using applications without the once-prohibitive initial investment cost in research and development; the same components are open to peer review by all researchers in the field, and are used for linguistic research as well. SphinxTrain is CMU Sphinx's training package. It trains models in Sphinx-3 format, which is also used by PocketSphinx. The Sphinx-2 format can also be converted to Sphinx-2 format under some conditions related to Sphinx-2's limitations. At this point, Sphinx-4 uses Sphinx-3 models.

CMUSphinx- base Sphinx is a speaker-independent large vocabulary continuous speech recognizer. It is also a collection of free and open source tools and resources that allows researchers and developers to build speech recognition systems. The packages that the CMU Sphinx Group is releasing are a set of reasonably mature, world-class speech components that provide a basic level of technology to anyone interested in creating speech-using applications without the once-prohibitive initial investment cost in research and development; the same components are open to peer review by all researchers in the field, and are used for linguistic research as well.

CMUSphinx2 Sphinx is a speaker-independent large vocabulary continuous speech recognizer. It is also a collection of free and open source tools and resources that allows researchers and developers to build speech recognition systems. The packages that the CMU Sphinx Group is releasing are a set of reasonably mature, world-class speech components that provide a basic level of technology to anyone interested in creating speech-using applications without the once-prohibitive initial investment cost in research and development; the same components are open to peer review by all researchers in the field, and are used for linguistic research as well. Sphinx-2 is a fast speech recognition system, the predecessor of PocketSphinx. It is not being actively developed at this time, but is still widely used in interactive applications. It uses Hidden Markov Models (HMM) with semi-continuous output probability density functions (PDF). Even though it is not as accurate as Sphinx-3 or Sphinx-4, it runs at real time, and therefore it is a good choice for live applications. You can find further documentation about Sphinx-2 in the release documentation, or at the online documentation.

CMUSphinx3 Sphinx is a speaker-independent large vocabulary continuous speech recognizer. It is also a collection of free and open source tools and resources that allows researchers and developers to build speech recognition systems. The packages that the CMU Sphinx Group is releasing are a set of reasonably mature, world-class speech components that provide a basic level of technology to anyone interested in creating speech-using applications without the once-prohibitive initial investment cost in research and development; the same components are open to peer review by all researchers in the field, and are used for linguistic research as well. Sphinx-3 is CMU's state-of-the-art large vocabulary speech recognition system. It uses Hidden Markov Models (HMM) with continuous output probability density functions (PDF). It supports several modes of operation. The more accurate mode, known as the "flat decoder", is descended from the original Sphinx-3 release (still available for reference purposes at https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/archive_s3/s3). The faster mode, known as the "tree decoder", was developed separately. The two decoders were merged in Sphinx 3.5, though the flat decoder was not fully functional until Sphinx 3.7. Further documentation can be found in the release documentation, or at the online documentation.

Clara OCR Clara OCR is an OCR for systems that support the C library and the X windows system (e.g. most flavours of Unix). It is intended for large scale digitalization projects, and features a powerful GUI and a web interface for cooperative digitalization of books. Clara OCR development started in 1999 and we're approaching production quality.

Dasher Dasher is a zooming predictive text entry application that uses the accessibility framework to provide application control functionality. It is ideal for situations where a keyboard is not usable. It now supports 80 different languages.

Dictator 'dictator' lets users read on-screen text faster and easier by using the Rapid Serial Visual Presentation (RSVP) method. Features include dynamic text flow, Unicode support, a bookmark manager, customizable Web references, customizable text import filters, fullscreen mode, and more.

Emacspeak Emacspeak is a suite of task-oriented tools that, through Emacs, provides speech-enabled access to the Web. With support for the freely downloadable IBM ViaVoice Outloud speech synthesis engine, Emacspeak makes GNU/Linux systems the first zero-cost (commercially available screenreaders typically double the cost of a personal computer) Internet access solution for blind and visually impaired users. Emacspeak speaks the underlying information of a visual display, not its contents. For example, if you use a calendar application with a screenreader you hear a sequence of meaningless numbers, but Emacspeak speaks the relevant date in an easily understood manner. The system uses audio formatting to increase the band-width of aural communication; changes in voice characteristic and inflection combine with non-speech auditory icons to create the equivalent of spatial layout, fonts, and graphical icons. This provides contextual feedback and shifts some of the burden of listening from the cognitive to the perceptual domain. The program comes with a default set of auditory icons; they can be replaced with any of the themes available (typically higher quality recordings).

Festival Festival is a general multi-lingual speech synthesis system. It offers a full text to speech system with various APIs, as well an environment for development and research of speech synthesis techniques. It is written in C++ with a Scheme-based command interpreter for general control.

GAIL 'GAIL' is a GTK+ module that provides accessibility support for GTK+ and libgnomecanvas by implementing AtkObjects for widgets in the two libraries. For example, if the module is loaded in a program which calls gtk_widget_get_accessible() for a GtkEntry, an instance of GailEntry is returned. This module is normally used with the atk-bridge GTK+ module from at-spi to allow an assistive technology, e.g a screenreader, to query or drive the program.

GMouseTool GMouseTool is a program that assists in the recovery and prevention of Repetitive Strain Injury (RSI). The program tracks your mouse movements and when you stop the mouse over any object a click is sent. It is possible to configure the GMouseTool to send left, right and double-clicks to any application. You can use GMouseTool to drag-and-drop objects too.

GNU Ocrad GNU Ocrad is an OCR (Optical Character Recognition) program based on a feature extraction method. It reads a bitmap image in pbm format and produces text in byte (8-bit) or UTF-8 formats. It includes a layout analyser able to separate the columns or blocks of text normally found on printed pages.

GOK The GNOME On-screen Keyboard (GOK) includes an alphanumeric keyboard and a keyboard for launching applications. Users specify keyboards and access methods in XML, which lets them modify existings methods and create new ones. Users can set key width, height, and spacing as well as visual and auditory feedback on highlighting and selection. GOK also dynamically creates keyboards to adapt to a specific situation by redisplaying user interface components of running applications directly within GOK as keyboards. The user then has efficient access to elements of the user interface and does not need to navigate the interface indirectly though keyboard accelerators. GOK also supports the redisplay of application menus and toolbars, and includes a window activator keyboard that lists the current windows and lets users switch between them.

Gnome-mag 'gnome-mag' defines a magnification service API and a sample implementation for GNOME 2. It includes a simple onscreen magnifier. It can be used in conjunction with GNOME Accessibility, for instance by clients of the at-spi interfaces (see http://developer.gnome.org/projects/gap/).
