Recipes

Please refer to https://icefall.readthedocs.io/en/latest/recipes/index.html for more information.

We provide two recipes at present:

• yesno
• LibriSpeech

yesno

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.

LibriSpeech

We provide two models for this recipe: conformer CTC model and TDNN LSTM CTC model.

Conformer 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:

TDNN LSTM 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:
