What's New in Julius-3.5.1 ?
=============================

Julius/Julian rev.3.5.1 enhances MFCC parameter extraction function to
enable direct speech recognition on various kinds of acoustic model.
It also improves direct microphone / network input recognition by
MAP-CMN. Bugs on module mode, large N-gram, multi-path version are
fixed.

Summary of changes in 3.5.1:

o Wider MFCC support to enable direct speech recognition on various AM:
- Added extraction of acceleration coefficients (_A).
- Support all MFCC qualifier conbination.
- Added options to specify detailed analysis parameters.

o Improved microphone / network recognition by MAP-CMN:
- Cepstral mean of last 5 second input is used as an initial mean
for each input. You can inhibit updating of the initial mean
and keep the value loaded by "-cmnload" by option "-cmnnoupdate".

o Module mode:
- Julius will output "<STARTPROC/>" when recognition starts, and
"<STOPPROC/>" after recognition stopped by module command.
It may help some server-client synchronization problem.

o Bug fixes:
- Sometimes segfault on pause/resume command on module mode.
- Can not read N-gram whose tuples > 2^24 (enbuged on 3.5).
- Can not read HMM with 3-state (1 output state) model on multi-path.
- Sometimes omit the last line in DFA file.
- Sometimes fails to compile gramtools on MacOSX.


All the changes are listed in "Release.txt".

From rev.3.4, a grammar-based recognizer called "Julian" is also
included. the Julian can be compiled from Julius sources by
specifying configure option "--enable-julian". The grammar format
Julian uses is original one based on BNF. A grammar compiler that
converts the written BNF to finite state grammar, and several test
tools are included in this archive.

tutorial, model formats and more, are available at:

It is basically based on rev.3.2, but will be also helpful for
recent versions.

3.5.1 (2006.03.31)
===================
o Wider MFCC types support:
- Added extraction of acceleration coefficients (_A). Now you
can recognize waveform or microphone input with AM trained with _A.
- Support all MFCC qualifiers (_0, _E, _N, _D, _A, _N, _Z) and their
combination
- Support for any vector lenth (will be guessed from AM header)
- New option: "-accwin"
- New option "-zmeanframe": frame-wise DC offset removal, like HTK
- New options to specify detailed analysis parameters (see manual):
-preemph, -fbank, -ceplif, -rawe / -norawe,
-enormal / -noenormal, -escale, -silfloor

o Improved microphone / network recognition by MAP-CMN:
- New option "-cmnmapweight" to change MAP weight
- Option "-cmnload" can be used to specify the initial cepstral
mean at startup
- Cepstral mean of last 5 second input is used as an initial mean
for each input. You can inhibit updating of the initial mean
and keep the value loaded by "-cmnload" by option "-cmnnoupdate".

o Module issue:
- Julius now outputs "<STARTPROC/>" when recognition starts, and
"<STOPPROC/>" after recognition stopped by module command.
Use this for safer server-client synchronization.
- now can specify grammar name from client by specifying a name
after a command like "ADDGRAM name" or "CHANGEGRAM name".

o Bug fixes:
- Sometimes segfault on pause/resume command on module mode while input.
- Can not read N-gram with tuples > 2^24.
- Can not read HMM with 3-state (1 output state) model on multi-path.
- Sometimes omit the last transition definition in DFA file.
- Sometimes fails to compile the gramtools on MacOSX.
