This is project for Korean Speech Recognition using LAS (Listen, Attend and Spell) models
implemented in PyTorch.
We appreciate any kind of feedback or contribution.
Speech recognition is an interdisciplinary subfield of computational linguistics that develops methodologies and technologies that enables the recognition and translation of spoken language into text by computers.
We mainly referred to following papers.
「SpecAugment: A Simple Data Augmentation Method for Automatic Speech Recognition」.
if you want to study the feature of audio, we recommend this papers.
「Voice Recognition Using MFCC Algirithm」.
Our project based on Seq2seq with Attention Architecture.
Seq2seq is a fast evolving field with new techniques and architectures being published frequently.
and We use AI Hub Dataset which contains 1,000 hours korean voice data.
And, our project is currently in progress.
At present our top model has recorded an 80% CRR, and we are working for a higher recognition rate.
( CRR : Character Recognition Rate )
This project recommends Python 3.7 or higher.
We recommend creating a new virtual environment for this project (using virtualenv or conda).
- Numpy:
pip install numpy(Refer here for problem installing Numpy). - PyTorch: Refer to PyTorch website to install the version w.r.t. your environment.
- Pandas:
pip install pandas(Refer here for problem installing Pandas) - librosa:
pip install librosa(Refer here for problem installing librosa) - tqdm:
pip install tqdm(Refer here for problem installing tqdm)
Refer here before Training.
The above document is written in Korean.
We will also write a document in English as soon as possible, so please wait a little bit.
If you already have another dataset, please modify the data set path to definition.py as appropriate.
if you want to start training, you should run train.py.
or after training, you want to start testing, you should run test.py.
you can set up a hyperparameters hparams.py.
An explanation of hparams is here.
If you have any questions, bug reports, and feature requests, please open an issue on Github.
or Contacts [email protected] please.
We appreciate any kind of feedback or contribution. Feel free to proceed with small issues like bug fixes, documentation improvement. For major contributions and new features, please discuss with the collaborators in corresponding issues.
We follow Google Python Style Guide for code style. Especially the style of docstrings is important to generate documentation.
