After wav2letter package is installed, please, have a look at the examples examples/ how to use classes and methods of wav2letter from python.
To run examples use the following commands:
- for ASG criterion using CUDA backend
python examples/criterion_example.py - for ASG criterion using CPU backend
python examples/criterion_example.py --cpu - lexicon beam-search decoder with KenLM word-level language model
python examples/decoder_example.py ../../src/decoder/test - featurization
python examples/feature_example.py ../../src/feature/test/data
