eSpeak is a compact open source software speech synthesizer for English
and other languages.
eSpeak uses a "formant synthesis" method. This allows many languages to
be provided in a small size. The speech is clear, and can be used at
high speeds, but is not as natural or smooth as larger synthesizers
which are based on human speech recordings.
