This repository offers a clean code version of the original repository from SeanNaren with classes and modular components (eg trainers, models, loggers...).
I have added a configuration file to manage the parameters set in the model. You will also find a pretrained model in japanese performing a CER = 34 on JSUT test set .
At a granular level, ASRDeepSpeech is a library that consists of the following components:
| Component | Description |
|---|---|
| asr_deepspeech | Speech Recognition package |
| asr_deepspeech.data | Data related module |
| asr_deepspeech.data.dataset | Build the dataset |
| asr_deepspeech.data.loaders | Load the dataset |
| asr_deepspeech.data.parsers | Parse the dataset |
| asr_deepspeech.data.samplers | Sample the dataset |
| asr_deepspeech.decoders | Decode the generated text |
| asr_deepspeech.loggers | Loggers |
| asr_deepspeech.modules | Components of the network |
| asr_deepspeech.parsers | Arguments parser |
| asr_deepspeech.tests | Test units |
| asr_deepspeech.trainers | Trainers |

)To clone and run this application, you'll need the following installed on your computer:
Install bpd:
# Clone this repository and install the code
git clone https://github.com/zakuro-ai/asr
# Go into the repository
cd asrExhaustive list of make commands:
pull # Download the docker image
sandbox # Launch the sandox image
install_wheels # Install the wheel
tests # Test the code
We are providing a support for local or docker setup. However we recommend to use docker to avoid any difficulty to run the code. If you decide to run the code locally you will need python3.6 with cuda>=10.1. Several libraries are needed to be installed for training to work. I will assume that everything is being installed in an Anaconda installation on Ubuntu, with Pytorch 1.0. Install PyTorch if you haven't already.
Note
Running this application by using Docker is recommended.
To build and run the docker image
make pull
make sandbox
Warning
Running this application by using PythonEnv is possible but not recommended.
make install_wheels
make tests
You should be able to get an output like
