Curation & Processing

  • All clips re-segmented to remove silence and cross-talk
  • Transcripts normalised to Unicode NFC; language tags added (<hi-en> for code-switched utterances)
  • Duplicate and near-duplicate clips removed
  • Consistent CSV schema applied across all sources before concatenation
  • Audio stored as WAV, original sample rates preserved
