# ASVspoof 5 (track 1, eval)

Benchmark-ready packaging of the **Track 1 (spoofing / deepfake detection) evaluation partition** of the ASVspoof 5 challenge, for speech anti-spoofing and synthetic / deepfake voice detection.

## Overview

Track 1 is binary classification: **bonafide** (genuine human speech) vs. **spoof** (synthetic / converted speech). This packaging contains the full track_1 evaluation set. The original challenge is at https://www.asvspoof.org/.

## License & redistribution

Redistributed under the **Open Data Commons Attribution License (ODC-By) v1.0**. See `LICENSE.txt`. Labels and the evaluation protocol are unmodified; audio is the original 16 kHz mono FLAC, embedded bit-exactly (no re-encode — a full decode probe of all 680,774 clips passed cleanly).

## Schema

| Column | Type | Description |
|--------|------|-------------|
| `path` | `string` | `<utterance_id>.flac`, unique |
| `audio` | `Audio(16000)` | 16 kHz mono FLAC |
| `label` | `ClassLabel` | `"bonafide"` (0) / `"spoof"` (1) |
| `notes` | `string` | JSON: `utterance_id`, `speaker_id`, `gender`, `codec`, `codec_id`, `source_id`, `attack_condition`, `attack_id` |

`notes` example:
```json
{"utterance_id": "E_0009538969", "speaker_id": "E_1607", "gender": "M", "codec": "C05", "codec_id": "2", "source_id": "E_0009486171", "attack_condition": "AC1", "attack_id": "A26"}
```

## Quick Start

```python
from datasets import load_dataset

ds = load_dataset("SpeechAntiSpoofingBenchmarks/ASVspoof5", split="test")
print(ds[0])
```

## Stats

| Stat | Value |
|------|-------|
| Total trials | 680,774 |
| Bonafide | 138,688 |
| Spoof | 542,086 |
