ESpeak1.37

ESpeak is a compact open source software speech synthesizer for English and other languages.

eSpeak produces good quality English speech. It uses a different synthesis method from other open source TTS engines, and sounds quite different. It's perhaps not as natural or "smooth", but I find the articulation clearer and easier to listen to for long periods.

It can run as a command line program to speak text from a file or from stdin. A shared library version is also available.
