View 3.5.1 - Change Log
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.
