Software for Text-to-Speech Software for Text-to-Speech

Windows has many little-used features that can make it easy for people with disabilities. One of those features, Text-to-Speech, can also be useful when you want to have your computer read information to you while you do something else.

Windows makes this possible through a built-in driver called a TTS engine that is able to recognize text. It can play displayed text back using a pre-generated voice. Although it is a very useful technology, the engine included with Windows provides limited text-to-speech functionality but you can obtain third-party engines from other manufacturers.

Speech API

SAPI is a standard Speech Application Interface developed by Microsoft.  Most Speech programs and voices use this Microsoft Speech Interface to allow the program and voices to work together. SAPI4 is an older version of the standard, supported by a wider variety of voices, especially older voices.  A newer version of this standard, SAPI5 is supported by most of the newer voices, with some voices.

Most versions of Windows come with either SAPI4 or SAPI5 installed already, but this is not always the case.  There are times when you may need to install one or both of these on your computer in order to allow Text To Speech programs to work, or to take advantage of some features.
