REXX Speech is an add-on DLL containing functions that can be called by a REXX script. These functions allow a REXX script to use a synthesized voice to speak text through the computer's sound card. This has the advantage of easily and efficiently providing audible instructions to visually impaired users without needing to resort to creating your own WAVE files (of a voice speaking those instructions). You can simply speak text directly through the sound card as easily as you would otherwise SAY it in a console window.
