### Dataset Summary

This is a database used for the Third Automatic Speaker Verification Spoofing
and Countermeasuers Challenge, for short, ASVspoof 2019 (http://www.asvspoof.org)
organized by Junichi Yamagishi, Massimiliano Todisco, Md Sahidullah, Héctor
Delgado, Xin Wang, Nicholas Evans, Tomi Kinnunen, Kong Aik Lee, Ville Vestman,
and Andreas Nautsch in 2019.

## Dataset Structure

### Data Instances

```
{'speaker_id': 'LA_0091',
 'audio_file_name': 'LA_T_8529430',
 'audio': {'path': 'D:/Users/80304531/.cache/huggingface/datasets/downloads/extracted/8cabb6d5c283b0ed94b2219a8d459fea8e972ce098ef14d8e5a97b181f850502/LA/ASVspoof2019_LA_train/flac/LA_T_8529430.flac',
  'array': array([-0.00201416, -0.00234985, -0.0022583 , ...,  0.01309204,

  'sampling_rate': 16000},
 'system_id': 'A01',
 'key': 1}
```

### Data Fields

Logical access (LA):
- `speaker_id`: `LA_****`, a 4-digit speaker ID
- `audio_file_name`: name of the audio file
- `audio`: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: `dataset[0]["audio"]` the audio file is automatically decoded and resampled to `dataset.features["audio"].sampling_rate`. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the `"audio"` column, *i.e.* `dataset[0]["audio"]` should **always** be preferred over `dataset["audio"][0]`.
- `system_id`: ID of the speech spoofing system (A01 - A19),  or, for bonafide speech SYSTEM-ID is left blank ('-')
- `key`: 'bonafide' for genuine speech, or, 'spoof' for spoofing speech

Physical access (PA):
- `speaker_id`: `PA_****`, a 4-digit speaker ID

- `audio_file_name`: name of the audio file

- `audio`: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: `dataset[0]["audio"]` the audio file is automatically decoded and resampled to `dataset.features["audio"].sampling_rate`. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the `"audio"` column, *i.e.* `dataset[0]["audio"]` should **always** be preferred over `dataset["audio"][0]`.

- `environment_id`: a triplet (S,R,D_s), which take one letter in the set {a,b,c} as categorical value, defined as

  |                                  | a      | b       | c        |
  | -------------------------------- | ------ | ------- | -------- |
  | S: Room size (square meters)     | 2-5    | 5-10    | 10-20    |
  | R: T60 (ms)                      | 50-200 | 200-600 | 600-1000 |
  | D_s: Talker-to-ASV distance (cm) | 10-50  | 50-100  | 100-150  |

- `attack_id`: a duple (D_a,Q), which take one letter in the set {A,B,C} as categorical value, defined as

  |                                     | A       | B      | C     |
  | ----------------------------------- | ------- | ------ | ----- |
  | Z: Attacker-to-talker distance (cm) | 10-50   | 50-100 | > 100 |
  | Q: Replay device quality            | perfect | high   | low   |

  for bonafide speech, `attack_id` is left blank ('-')

- `key`: 'bonafide' for genuine speech, or, 'spoof' for spoofing speech

### Data Splits

|          | Training set | Development set | Evaluation set |
| -------- | ------------ | --------------- | -------------- |
| Bonafide | 2580         | 2548            | 7355           |
| Spoof    | 22800        | 22296           | 63882          |
| Total    | 25380        | 24844           | 71237          |
