Direct speech messages, beyond the default speech of a screen reader program, can significantly increase the usability of a software application for persons who operate a computer nonvisually. SayTools is a free collection of software, provided in both source code and executable forms, for developers to conveniently add speech to an application. It is able to detect whether the JAWS, NVDA, System Access, or Window-Eyes screen reader is running, and speak through the relevant API if found. It can also use the computer's default SAPI speech, or play audio files. Interested developers can either ask users to install SayTools, or incorporate it within the installer of a distributed application.
