数据介绍

Libri-Light offers 60+ k hours of unlabelled speech, a small training set for limited supervision (10h, 1h or 10 minutes of labelled speech), and a common set of metrics to evaluated three settings:

  1. the unsupervised/zero-resource setting. Here, models are trained only on unlabelleds speech and attempt to construct 'good' speech representations. They are evaluated with the ABX metric.
  2. the semi-supervised setting. Here, models are trained with the limited supervision dataset and exploit the unlabelled in various ways (as pretraining, to get pseudo-labels, etc). The models are evaluated using either PER or WER.
  3. the distant supervision setting. Here, models can use additional unaligned text to build a decoder. These models are evaluated using WER.

Documentation

Documentation for downloading Libri-Light or preparing the source files from scratch can be found in data_preparation.

The eval directory contains ABX, PER and WER evaluations on pretrained CPC models.

The baselines directory contains pretrained wav2letter baseline models and information about reproduction.
