About Julius
=============

"Julius" is a high-performance, two-pass large vocabulary continuous
speech recognition (LVCSR) decoder software for speech-related
researches and developments.  It supports N-gram based dictataion (N
unlimited) , 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 support for
"hot plugging" of arbitrary modules at run time.  The core engine is
implemented as a C library along with a simple API, which can be
easily integrated into various applications.  Standard model formats
for famous tools such as HTK, CMU-Cam SLM toolkit, etc. are adopted.

The main platform is Linux and other Unix workstations, and also works
on Windows (SAPI/console). Julius is distributed with open license
together with source codes.


What's new in Julius-4.0
==========================

The Julius rev.4.0 is a full major version up, a re-innovation of the
decoder as a flexible speech recognition engine.  The internal
structures are re-organized and modularized thoroughly, which results
in the librarization of core engine, enhancement and unification of
language model, realization of multi-decoding with hot plugging
feature.  The major features are listed below:

 - Engine core becomes separate C library with simple API
 - Can handle various LM, thus Julius and Julian are integrated
 - Multi-decoding with multiple models
 - Support to add and remove models while running the decoder
 - Support N-gram longer than 4 (N now unlimited)
 - User-defined LM function
 - Confusion network output
 - GMM-based and decoder-based VAD
 - New tools added, new functions added
 - Memory efficiency is improved

Julius-4.0 ensures the compatibility with Julius-3.x for its usage and
Jconf configuration, so that one can easily migrate to Julius-4.
The decoding performance of Julius-4.0 is still kept as the same as
the latest release (Julius-3.5.3) for now.
