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

"Julius" is an open-source high-performance large vocabulary
continuous speech recognition (LVCSR) decoder software for
speech-related researchers and developers.  Based on word N-gram and
triphone context-dependent HMM, it can perform almost real-time
decoding on most current PCs with small amount of memory.

It also has high vesatility. The acoustic models and language models
are pluggable, and you can build various types of speech recognition
system by building your own models and modules to be suitable for your
task.  It also adopts standard formats to cope with other toolkit such
as HTK, CMU-Cam SLM toolkit, etc.

The core engine is implemented as embeddable library, to aim to offer
speech recognition capability to various applications.  The recent
version supports plug-in capability so that the engine can be extended
by user.

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-4.3
===========================

Version 4.3 includes several new features to support on-line DNN-HMM
decoding: decoding with state output probability vectors ("outprob
vectors") as input, network-based feature / outprob vector input,
improved cepstral variance normalization (CVN) for real-time
recognition, FBANK/MELSPEC feature support and so on.  Also the tool
"adintool" is now capable of extracting and sending feature vectors in
real-time via network.

New options:
  [-input vecnet]       read feature / outprob vectors from network
  [-input outprob]      read outprob vectors from HTK parameter file
  [-outprobout [file]]  save computed outprob vectors to HTK file (for debug)

A short test of network-based feature transmission:

  [server]
  % julius -C file.jconf -input vecnet

  [client with microphone]
  % adintool -in mic -out vecnet -paramtype MFCC_E_D_N_Z -veclen 25 -C file.jconf

You should set appropriate feature vector's type and length to
adintool with "-paramtype TYPE", "-veclen length".  You should also
set feature extraction parameters as the same as Julius.  Since
adintool uses JuliusLib for the extraction, it accepts Jconf file and
setting options as same as Julis.  So the easier way is to apply the
same Jconf file to adintool with "-C" option as shown above.

See the "Release.txt" file for the full list of updates.
Run with "-help" to see full list of options.
