LibriSpeech: An ASR corpus based on public domain audio books

This is a mirror of the LibriSpeech ASR corpus. The original files were converted from FLAC to Opus to reduce the size and accelerate streaming. The transcripts are not included. This mirror is thus best suited for audio-to-audio tasks.

• Sampling rate: 16 kHz
• Channels: 1
• Format: Opus
• Splits:
  • Train: 460 hours, 132553 utterances, train-clean-100 and train-clean-360 sets.
  • Validation: 7 hours, 2703 utterances, dev-clean set.
  • Test: 7 hours, 2620 utterances, test-clean set.
