# SADA 2022 Arabic Diarization
Training-ready speaker-attributed ASR windows derived from
[SADA 2022](https://www.kaggle.com/datasets/sdaiancai/sada2022). The source
recordings are mirrored at
[khaledalganem/sada2022](https://huggingface.co/datasets/khaledalganem/sada2022).
## Splits
- `train`: 36,004 windows, 202.064 hours, 4,062 recordings
- `validation`: 853 windows, 4.774 hours, 88 recordings
- `test`: 901 windows, 5.006 hours, 111 recordings
Total: **37,758 windows** and
**211.844 hours**.
The official SADA train, validation, and test partitions are preserved.
Windows are 8–28 seconds, contain 1–4 locally remapped speakers, and have at
least 45% annotated speech. Windows from the same source
recording do not materially overlap. Ambiguous speaker labels and overlapping
speech annotations are excluded from v1.
Audio is resampled to 16 kHz mono FLAC. Background noise and music are retained;
no denoising is applied.
## Columns
- `audio`: prepared FLAC window
- `segments`: speaker, timestamps, transcript, dialect, gender, age, environment
- `target`: SyvAI-style speaker/timestamp/text sequence
- `source_file`, `source_start`, `source_end`: source provenance
- `speaker_count`, `turn_count`, `speech_coverage`, `environment`
- `audio_sha256`, `qa_flags`, `review_status`, `license`
## Target format
```text
<|spltoken0|><|t:0.0|>السلام عليكم<|t:2.1|>
```
Speaker IDs are local to each window and ordered by first appearance.
Timestamp tokens use 100 ms resolution.

Changes made: selected timestamped regions, excluded unsupported annotations,
remapped speaker IDs locally, resampled audio, encoded FLAC, and generated
speaker-attributed sequence targets.

## `train-v1`: balanced real + conversational mixtures
`train-v1` is a non-commercial Arabic speaker-attributed ASR training
configuration derived entirely from SADA2022. It contains **30,000
windows / 164.317 hours**:
- 17,727 selected real SADA TRAIN windows (102.061 h)
- 12,273 deterministic conversational mixtures (62.256 h)
- speaker counts 1/2/3/4: 6,000 / 9,000 / 9,000 / 6,000
- synthetic active-speech overlap: 13.95%
- 60 Parquet shards with embedded 16 kHz mono FLAC
The official SADA validation and test material is **not included** in this
configuration. Source recordings are disjoint from held-out recordings and
the final audit found zero held-out ID overlap.
### Fields
- `audio`: embedded 16 kHz mono FLAC (`bytes`, `path`)
- `text`: Arabic transcript without control tokens
- `target`: `<|spltokenK|><|t:start|>text<|t:end|>` sequence; no count token
- `segments`: structured local speaker, start/end seconds, and text
- `rttm_text`: exact RTTM activity labels
- `speaker_count`, overlap statistics/bucket, and pause durations
- `real_vs_synthetic`, recipe version, recipe JSON, and source provenance
- audio, row, shard, and source checksums
- split, attribution, and license metadata
### Synthetic method and limitations
Mixtures use full annotated Arabic utterances from canonical SADA TRAIN
recordings, deterministic seed 30072026, conversational pause sampling, and
none/light/medium/heavy overlap buckets. At most two speakers overlap and no
utterance is clipped to create an interruption.
SADA speaker labels are file-local. Different source recordings are treated
as distinct speaker proxies, but they are not proven to contain different
people. The material is Saudi broadcast speech and is not a complete model of
all Arabic dialects, channels, or spontaneous conversation.
