YODAS2 is the long-form dataset from YODAS dataset.

It provides the same dataset as espnet/yodas but YODAS2 has the following new features:

  • formatted in the long-form (video-level) where audios are not segmented.
  • audios are encoded using higher sampling rates (i.e. 24k)

For detailed information about YODAS dataset, please refer to our paper and the espnet/yodas repo.

Usage:

Each data point corresponds to an entire video on YouTube, it contains the following fields:

  • video_id: unique id of this video (note this id is not the video_id in Youtube)
  • duration: total duration in seconds of this video
  • audio
    • path: local path to wav file if in standard mode, otherwise empty in the streaming mode
    • sampling_rate: fixed to be 24k. (note that the sampling rate in espnet/yodas is 16k)
    • array: wav samples in float
  • utterances
    • utt_id: unique id of this utterance
    • text: transcription of this utterance
    • start: start timestamp in seconds of this utterance
    • end: end timestamp in seconds of this utterance

YODAS2 also supports two modes:

standard mode: each subset will be downloaded to the local dish before first iterating. 

from datasets import load_dataset

# Note this will take very long time to download and preprocess
# you can try small subset for testing purpose
ds = load_dataset('espnet/yodas2', 'en000')
print(next(iter(ds['train'])))

streaming mode most of the files will be streamed instead of downloaded to your local deivce. It can be used to inspect this dataset quickly.

from datasets import load_dataset

# this streaming loading will finish quickly
ds = load_dataset('espnet/yodas2', 'en000', streaming=True)
