Emacspeak is a free computer application, a speech interface and an audio desktop (as opposed to a screen reader) employing Emacs, which is written in C, Emacs Lisp and Tcl and developed principally by T. V. Raman (himself blind since childhood, and who has worked on voice software with Adobe Software and later IBM) and first released April 1995; it is portable to all POSIX-compatible OSs. It is tightly integrated with Emacs, allowing it to render intelligible and useful content rather than parsing the graphics (hence it is sometimes referred to not as a separate program, but a subsystem of Emacs proper); its default voice synthesizer (as of 2002, IBM's ViaVoice Text-to-Speech (TTS)) can be replaced with other software synthesizers when a server module is installed. Emacspeak is one of the most popular speech interfaces for Linux, bundled with most major distributions. The following article is written on 20th anniversary of Emacspeak 
Emacspeak achieves its integration by being written largely in Emacs Lisp using "advice", enabling it to literally be a wrapper around most functions that change or otherwise modify the display. Auditorily, verbalizations are pre-emptible, and common actions like opening a menu or closing a file have a brief sound associated with that particular action; it also immediately verbalizes all insertions of characters, and attempts to speak as much of the context sentences around the cursor's present location as possible.
