Statistics
| Metric | Value |
|---|---|
| Source files | 5 |
| Train samples | 558 |
| Validation samples | 50 |
| Total duration | 587.1 minutes |
Columns
| Column | Type | Description |
|---|---|---|
audio |
Audio | Audio segment (16kHz) - speech only, silence stripped via VAD |
text |
string | Plain transcription (no timestamps) - backwards compatible |
text_ts |
string | Transcription WITH Whisper timestamp tokens (e.g., `< |
start_time |
string | Segment start in original audio (HH:MM:SS.mmm) |
end_time |
string | Segment end in original audio (HH:MM:SS.mmm) |
speech_duration |
float | Duration of speech in segment (excluding silence) |
word_timestamps |
list | Word-level timestamps (relative to speech-only audio) |
source_file |
string | Original 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
