Julius is a high-performance, two-pass large vocabulary continuous speech recognition (LVCSR) engine.

It supports N-gram based dictation, DFA grammar based parsing, and one-pass isolated word recognition. Phone context dependencies are supported up to triphone. It can perform a multi-model decoding, a recognition using several LMs and AMs simultaneously with a single processor, and also supports "hot plugging" of arbitrary modules at run time.

This package contains the executable applications, a set of tools useful to build recognition grammar and some examples (like a script to use Julius to execute some predetermined commands).
