Install tools

Requirements

• NVIDIA CUDA GPU
• CUDA Toolkit (8.0 <= version <= 10.1)

Install kaldi and python environment

cd tools
make

• This command builds kaldi at tools/kaldi
  • if you want to use pre-build kaldi

    cd tools
    make KALDI=<existing_kaldi_root>

    This option make a symlink at tools/kaldi
• This command extracts miniconda3 at tools/miniconda3, and creates conda envirionment named 'eend'
• Then, installs Chainer and cupy into 'eend' environment
  • use CUDA in /usr/local/cuda/
    • if you need to specify your CUDA path

      cd tools
      make CUDA_PATH=/your/path/to/cuda-8.0

      This command installs cupy-cudaXX according to your CUDA version. See https://docs-cupy.chainer.org/en/stable/install.html#install-cupy

Test recipe (mini_librispeech)

Configuration

• Modify egs/mini_librispeech/v1/cmd.sh according to your job schedular. If you use your local machine, use "run.pl". If you use Grid Engine, use "queue.pl" If you use SLURM, use "slurm.pl". For more information about cmd.sh see http://kaldi-asr.org/doc/queue.html.

Data preparation

cd egs/mini_librispeech/v1
./run_prepare_shared.sh

Run training, inference, and scoring

./run.sh

• See RESULT.md and compare with your result.

CALLHOME two-speaker experiment

Configuraition

• Modify egs/callhome/v1/cmd.sh according to your job schedular. If you use your local machine, use "run.pl". If you use Grid Engine, use "queue.pl" If you use SLURM, use "slurm.pl". For more information about cmd.sh see http://kaldi-asr.org/doc/queue.html.
• Modify egs/callhome/v1/run_prepare_shared.sh according to storage paths of your copora.

Data preparation

cd egs/callhome/v1
./run_prepare_shared.sh

Self-attention-based model (latest configuration)

./run.sh

BLSTM-based model (old configuration)

local/run_blstm.sh
