Text-to-Speech Software for Linux
If you've been using Mac OS X or Windows Vista before, you may be a bit disappointed to learn that there's no speech synthesizer or text-to-speech (TTS) application that is installed by default on your Linux distribution. For those of you who don't know what a speech synthesizer is, it's simply a computer program that converts normal language text into speech. Text-to-speech software can be of great help particularly for people who are visually impaired and those who are mute.
If you've been looking for a free speech synthesizer for Linux, the one that I can highly recommend is a program called Festival.
