We support importing Kaldi data directories that contain at least the wav.scp file, required to create the RecordingSet. Other files, such as segments, utt2spk, etc. are used to create the SupervisionSet.
We currently do not support the following (but may start doing so in the future):
- Importing Kaldi's extracted features (
feats.scpis ignored) - Exporting Lhotse manifests as Kaldi data directories.
Python methods related to Kaldi support:
lhotse.kaldi
Converting Kaldi data directory called data/train, with 16kHz sampling rate recordings, to a directory with Lhotse manifests called train_manifests:
lhotse convert-kaldi data/train 16000 train_manifests
