Text-to-Speech software is used to convert words from a computer document (e.g. word processor document, web page) into audible speech spoken through the computer speaker.

The text to speech software reads text words with different voices that can be chosen. The text words may be on the screen, in the clipboard, from a text file or other source. The technology synthesizes natural sounding speech from ordinary text. The text can just be copied to the clipboard or imported from text files. The software then reads the text to the user or converts the text to mp3 or wav file. It also allows the conversion of text into a MP3/WAV audio file that can be listened later.

The text to speech converter has the capability to extract variable information from a database (or from the Web) that is later converted into audible speech. The applications of the software include:

Call centers in particular can become instantly more productive by letting the phone system provide the caller with information and by determining the best service representative to handle other requests.
