• Latency control BLstm

• CTC in two ways(Warp-CTC vs Eesen)

• Skip training & decode

• Graph network(eg multi-input, multi-output, add and splice)

• Row Convolution

• GRU

• FSMN

• vad

• online

• parallel(MPI based multi-card speedup)

• BSP

• ASGD

• EASGD

• BMUF

• kws

Install

kaldi-aslp compile just like the standard kaldi recipe.

First, compile kaldi dependent tools if the network is not avaliable, You can download kaldi depending tools from here.

cd tools
make

Then, go to src dir, modify aslp.mk, change the compile switch as you like

# Optional make warp-ctcUSE_CTC = trueUSE_WARP_CTC = false# Optinal make mpi parallel(aslp-paralle aslp-parallelbin)USE_MPI = true# Optinal make online part, Online depends on crf++, add it's lib and includeUSE_ONLINE = falseCRF_ROOT = /home/zhangbinbin/zhangbinbin/kaldi-aslp/src/crf
CRF_FLAGS = /home/zhangbinbin/zhangbinbin/kaldi-aslp/src/crf/libcrfpp.a

Last, just configure and compile.

cd src
./configure
make -j 24

How to Use?

To use it, just copy aslp_scripts to your project, add kaldi-aslp bin dir to your path.sh

export KALDI_ROOT=`pwd`/../../../
[ -f $KALDI_ROOT/tools/env.sh ] && . $KALDI_ROOT/tools/env.sh 
export PATH=$PWD/utils/:$KALDI_ROOT/src/bin:$KALDI_ROOT/tools/openfst/bin:$KALDI_ROOT/src/fstbin/:$KALDI_ROOT/src/gmmbin/:$KALDI_ROOT/src/featbin/:$KALDI_ROOT/src/lm/:$KALDI_ROOT/src/sgmmbin/:$KALDI_ROOT/src/sgmm2bin/:$KALDI_ROOT/src/fgmmbin/:$KALDI_ROOT/src/latbin/:$KALDI_ROOT/src/nnetbin:$KALDI_ROOT/src/nnet2bin/:$KALDI_ROOT/src/kwsbin:$KALDI_ROOT/src/online2bin/:$KALDI_ROOT/src/ivectorbin/:$KALDI_ROOT/src/lmbin/:$KALDI_ROOT/src/nnet3bin/:$PWD:$KALDI_ROOT/src/aslp-nnetbin/:$KALDI_ROOT/src/aslp-bin/:$KALDI_ROOT/src/aslp-vadbin/:$KALDI_ROOT/src/aslp-parallelbin:$KALDI_ROOT/src/aslp-onlinebin:$PATHexport LC_ALL=C
