Train on your data

In order to train the model on your data follow the steps below

1. data preprocessing

• prepare your data and make sure the data is formatted in an CSV format as below

audio_path,text,duration
file/to/file.wav,the text in that file,3.2 

• make sure the audios are MONO if not make the proper conversion to meet this condition

2. Setup development environment

• create enviroment

python -m venv env

• activate the enviroment

source env/bin/activate

• install the required dependencies

pip install -r requirements.txt

3. Training

• update the config file if needed
• train the model
  • from scratch

  python train.py

  • from checkpoint

  python train.py checkpoint=path/to/checkpoint tokenizer.tokenizer_file=path/to/tokenizer.json
  

TODO

• Compeleting the inference module
• Adding Demo
