Columns

ColumnTypeDescription
audioAudioAudio segment (16kHz) - speech only, silence stripped via VAD
textstringPlain transcription (no timestamps) - backwards compatible
text_tsstringTranscription WITH Whisper timestamp tokens (e.g., `<0.00>Hello<0.50>`)
start_timestringSegment start in original audio (HH:MM:SS.mmm)
end_timestringSegment end in original audio (HH:MM:SS.mmm)
speech_durationfloatDuration of speech in segment (excluding silence)
word_timestampslistWord-level timestamps (relative to speech-only audio)
source_filestringOriginal audio filename

VAD Processing

Audio segments are processed with Silero VAD to match faster-whisper inference:

  • —Silence is stripped from audio (only speech regions remain)
  • —Timestamps are relative to the concatenated speech audio
  • —This ensures training data matches inference behavior

Training Usage

For Whisper timestamp training, use the two-bucket approach:

  • —Bucket A (50%): Use text - plain transcription without timestamps
  • —Bucket B (50%): Use text_ts - transcription with Whisper timestamp tokens

Usage

python
from datasets import load_dataset

dataset = load_dataset("Trelis/sample-dataset-test-neural-nopack")
