We provide two recipes at present:

• yesno
• LibriSpeech

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:

We provide a Colab notebook to run a pre-trained conformer CTC model:

The WER for this model is:

We provide a Colab notebook to run a pre-trained TDNN LSTM CTC model:

Once you have trained a model in icefall, you may want to deploy it with C++, without Python dependencies.

Please refer to the documentation https://icefall.readthedocs.io/en/latest/recipes/librispeech/conformer_ctc.html#deployment-with-c for how to do this.

We also provide a Colab notebook, showing you how to run a torch scripted model in k2 with C++. Please see:
