'''Assistive Technology Service Provider Interface''' ('''AT-SPI''') is, as was the intention from the beginning, a platform-neutral framework for providing bi-directional communication between assistive technologies (AT) and applications.<ref>{{cite web | url = http://www.linuxfoundation.org/collaborate/workgroups/accessibility/atk/at-spi/overview| title = ATK/AT-SPI SIG Overview | accessdate = 2014-04-10 }}</ref> It is the de- facto standard for providing accessibility to free and open desktops, like GNU/Linux or OpenBSD, leading by the [[GNOME project|GNOME Project]].

One common nomenclature to explain an accessibility framework is a usual client-server arquitecture. In that way, [[Assistive technology#Computer accessibility|Assistive Technologies]] (ATs) like [[screen readers]], would be the clients of that framework, and computer applications would be the server. In this arquitecture client and server needs to communicate each other, usually using the [[Inter-process communication|IPC]] technology of the platform. Ideally the accessibility framework expose this to the client and server in a transparent way.
