# PyAra — Russian Audio Deepfake Detection

Benchmark-ready packaging of **PyAra**, a Russian-language audio anti-spoofing
dataset (source: https://www.kaggle.com/datasets/alep079/pyara).

## Overview

Binary classification: **bonafide** (genuine Russian human recordings) vs.
**spoof** (synthetic / converted speech). The spoof side is produced by **five**
generation algorithms (`alg_1` … `alg_5`). Label is the top-level source
directory (`Real/` → bonafide, `Fake/` → spoof), per the `fake` column of
`final_dataset.tsv`.

International (CC BY-NC-SA 4.0)** license. Redistribution and adaptation are
permitted for **non-commercial** use with attribution and ShareAlike; this
packaging is itself CC BY-NC-SA 4.0. See `LICENSE.txt`. Audio is the original
16 kHz mono WAV, embedded bit-exactly (no re-encode — a full decode probe of all
clips passed cleanly).

## Schema

| Column | Type | Description |
|--------|------|-------------|
| `path` | `string` | source-relative path, e.g. `Fake/alg_1_0.wav`, unique |
| `audio` | `Audio(16000)` | 16 kHz mono WAV |
| `label` | `ClassLabel` | `"bonafide"` (0) / `"spoof"` (1) |
| `notes` | `string` | JSON: `utterance_id`, `algorithm`, `gender`, `age`, `length` |

`notes` example:
```json
{"utterance_id": "alg_1_0", "algorithm": "alg_1", "gender": "male", "age": "twenties", "length": "5.55"}
```

`utterance_id` is the source filename stem (`real_12713`, `alg_1_0`) — unique
across the whole set.

## Quick Start

```python
from datasets import load_dataset

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

## Stats

| Stat | Value |
|------|-------|

| Spoof algorithms | alg_1 (46,505), alg_2 (10,065), alg_3 (11,165), alg_4 (25,412), alg_5 (35,048) |
| Language | Russian |
| Sample rate | 16 kHz mono |
