"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.
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.
