Tiny Example

  1. source path.sh
  2. set CUDA_VISIBLE_DEVICES as you need.
  3. demo scrpt is bash run.sh. You can run commond separately as needed.

Steps

  • Prepare the data

    bash local/data.sh
    

    data.sh will download dataset, generate manifests, collect normalizer's statistics and build vocabulary. Once the data preparation is done, you will find the data (only part of LibriSpeech) downloaded in ${MAIN_ROOT}/dataset/librispeech and the corresponding manifest files generated in ${PWD}/data as well as a mean stddev file and a vocabulary file. It has to be run for the very first time you run this dataset and is reusable for all further experiments.

  • Train your own ASR model

    bash local/train.sh
    

    train.sh will start a training job, with training logs printed to stdout and model checkpoint of every pass/epoch saved to ${PWD}/checkpoints. These checkpoints could be used for training resuming, inference, evaluation and deployment.

  • Case inference with an existing model

  • Evaluate an existing model

    bash local/test.sh
    

    test.sh will evaluate the model with Word Error Rate (or Character Error Rate) measurement. Similarly, you can also download a well-trained model and test its performance:

  • Export jit model

    bash local/export.sh ckpt_path saved_jit_model_path
