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.
