We provide two recipes at present:
This is the simplest ASR recipe in icefall and can be run on CPU.
Training takes less than 30 seconds and gives you the following WER:
[test_set] %WER 0.42% [1 / 240, 0 ins, 1 del, 0 sub ]
We do provide a Colab notebook for this recipe.
We provide two models for this recipe: conformer CTC model and TDNN LSTM CTC model.
The best WER we currently have is:
| test-clean | test-other | |
|---|---|---|
| WER | 2.57% | 5.94% |
We provide a Colab notebook to run a pre-trained conformer CTC model:
The WER for this model is:
| test-clean | test-other | |
|---|---|---|
| WER | 6.59% | 17.69% |
We provide a Colab notebook to run a pre-trained TDNN LSTM CTC model:
