# Zeroth-Korean Dataset
|
38 |
+
|
39 |
+
## Introduction
|
40 |
+
The Zeroth-Korean dataset is a publicly available speech dataset created for Korean automatic speech recognition (ASR) research and development. This dataset is distributed under the CC BY 4.0 license, allowing anyone to use it freely. The goal of the Zeroth project is to make Korean speech recognition more widely accessible.
|
41 |
+
|
42 |
+
## Dataset Overview
|
43 |
+
- **Total Data**: Approximately 51.6 hours of training data and 1.2 hours of test data
|
44 |
+
- **Number of Utterances**: 22,263 utterances in the training set and 457 utterances in the test set
|
45 |
+
- **Number of Speakers**: 105 speakers in the training set, 10 speakers in the test set
|
46 |
+
- **Sampling Rate**: 16kHz
|
47 |
+
|
48 |
+
## Version Information
|
49 |
+
### Version 2.0.0
|
50 |
+
- **Changes**:
|
51 |
+
- Instead of downloading the original files directly from openslr.org, the data is distributed using pyarrow for more efficient storage.
|
52 |
+
- The `audio` field has been updated from `numpy.ndarray` to `datasets.Audio` type for improved accessibility of audio data.
|
53 |
+
- The `file` field has been renamed to `path`.
|
54 |
+
|
55 |
+
## Dataset Composition
|
56 |
+
- **Training Data (Train)**: Consists of 51.6 hours of Korean utterances, with a total of 22,263 utterances. This data is used to train speech recognition models.
|
57 |
+
- **Test Data (Test)**: Consists of 1.2 hours of utterances, with a total of 457 utterances, used for evaluating model performance.
|
58 |
+
|
59 |
+
### Data Fields
|
60 |
+
- **id**: Unique identifier for each utterance (string)
|
61 |
+
- **speaker_id**: Speaker identifier (int64)
|
62 |
+
- **chapter_id**: Chapter identifier (int64)
|
63 |
+
- **path**: Path to the audio file (string)
|
64 |
+
- **audio**: Audio data (managed as `datasets.Audio` type, sampling rate 16kHz)
|
65 |
+
- **text**: Transcribed text of the utterance (string)
|
66 |
+
|
67 |
+
## Usage Example
|
68 |
+
The Zeroth-Korean dataset can be easily loaded using the Hugging Face library.
|
69 |
+
|
70 |
+
```python
|
71 |
+
from datasets import load_dataset
|
72 |
+
|
73 |
+
# Load Zeroth-Korean dataset
|
74 |
+
dataset = load_dataset("kresnik/zeroth_korean")
|
75 |
+
|
76 |
+
# Print an example from the training dataset
|
77 |
+
print(dataset['train'][0])
|
78 |
+
```
|
79 |
+
|
80 |
+
## License
|
81 |
+
This dataset follows the [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) license. This license allows the data to be used freely, provided the source is properly credited.
|
82 |
+
|
83 |
+
The uploader has transferred the publicly available data from openslr.org to the Hugging Face Hub and did not participate in the creation of the dataset. This dataset is provided to facilitate broader accessibility of the original dataset.
|
84 |
+
|
85 |
+
The Zeroth project was developed through the collaboration of Lucas Jo (@Atlas Guide Inc.) and Wonkyum Lee (@Gridspace Inc.).
