### Dataset Summary
The CryCeleb2023 dataset is a compilation of cries gathered from 786 infants from various hospitals. \
The 26k audio files make up 6.5 hours of pure expiration sounds. \
The dataset also contains information on the time of recording, which is either within the first hour(s) of life or \
upon hospital discharge, typically within 24 hours of birth.

### Supported Tasks and Leaderboards

[CryCeleb2023 competition](https://huggingface.co/spaces/competitions/CryCeleb2023)

## Dataset Structure

Audio folder contains short wav files (16 kHz wav PCM).

*audio* - folder with audio files structured by infant ID
```
audio/
  train/
    spk1/
      B/
        spk1_B_001.wav
        ...
        spk6_B_001.wav
      ...
      D/
        spk1_D_001.wav
        ...
    ...
    spk586
      ...
  dev/
    ...(similar to train)...
  test/
    anonymous1/
      B/
        ...
```

In this folder structure:
- spkN: folder with recordings corresponding to baby N
- B/D: time of recording (birth or discharge)
- 001, 002,, etc - chronological index of cry sound (expiration)

*metadata.csv* - metadata associated with each audio file

*dev_pairs.csv* - pairs of birth/discharge recordings used for evaluating development set (available to challenge participants)

*test_pairs.csv* - pairs of birth/discharge recordings used in CryCeleb2023 evaluation (public and private scores)

### Data Instances

Audio files 16 kHz wav PCM - manually segmented cry sounds (expirations)

### Data Splits

Number of Infants by Split and Time(s) of Recording(s)

| Time(s) of Recording | train | dev  | test |
| --- | --- | --- | --- | 
| Both birth and discharge | 348 | 40 | 160  |
| Only birth | 183 | 0 | 0 |
| Only discharge | 55 | 0 | 0 |
| | 586 | 40 | 160 |


### Source Data

Audio recordings of infant cries made by android application

### Annotations

#### Annotation process

- Manual segmentation of cry into three categories: expiration, inspiration, no cry
- Only expirations kept in this corpus
- Manual review to remove any PIIs

### Personal and Sensitive Information

PII such as intelligible background speech, etc, were removed from the data.

All identities are also anonymized.

## Considerations for Using the Data


### Discussion of Biases

The dataset only covers infants born in one country

### Other Known Limitations

Dataset only includes expirations.

Recording quality varies
