## Dataset Description
GigaSpeech 2 is an evolving, large-scale, multi-domain, and multilingual ASR corpus focusing on low-resource languages. GigaSpeech 2 raw comprises about 30,000 hours of automatically transcribed speech, across Thai, Indonesian, and Vietnamese. GigaSpeech 2 refine consists of 10,000 hours of Thai, 6,000 hours each for Indonesian and Vietnamese.

### Example Usage
TODO:
### Supported Tasks and Leaderboards
- `automatic-speech-recognition`: The dataset can be used to train a model for Automatic Speech Recognition (ASR). The model is presented with an audio file and asked to transcribe the audio file to written text. Evaluation metrics includes Character Error Rate (CER) for Thai, and Word Error Rate (WER) for Indonesian and Vietnamese. The task has an active leaderboard which can be found at https://github.com/SpeechColab/GigaSpeech2#leaderboard and ranks models based on their WER.
### Languages
Gigaspeech 2 contains audio and transcription data in Thai, Indonesian, Vietnamese.

### Data Instances
```shell
Audio file (.wav):
Channels: 1
Sample Rate: 16000
Sample Encoding: 16-bit Signed Integer PCM
Transcript file (.tsv):
<segment_id>\t<text>\n
```
### Data Fields
- segment_id (string) - string id of the segment.
- text (string) - transcription of the segment.
### Data Splits
The dataset has three subsets: train, dev and test.
The train set has two configurations: raw, refined. train_raw contains all the data from train_refined.
#### Transcribed Training Subsets Size
| | Thai (hours) | Indonesian (hours) | Vietnamese (hours) |
|:--------------------:|:------------:|:------------------:|:------------------:|
| GigaSpeech 2 raw | 12901.8 | 8112.9 | 7324.0 |
| GigaSpeech 2 refined | 10262.0 | 5714.0 | 6039.0 |
GigaSpeech 2 raw contains all the data from GigaSpeech 2 refined.
#### Transcribed Evaluation Subsets
| | Thai (hours) | Indonesian (hours) | Vietnamese (hours) |
|:--------------------:|:------------:|:------------------:|:------------------:|
| GigaSpeech 2 dev | 10.0 | 10.0 | 10.2 |
| GigaSpeech 2 test | 10.0 | 10.0 | 11.0 |
## Dataset Creation
### Source Data
* GigaSpeech 2 raw: 30,000 hours of automatically transcribed speech across Thai, Indonesian, and Vietnamese.
* GigaSpeech 2 refined: 10,000 hours of Thai, 6,000 hours each for Indonesian and Vietnamese.
* GigaSpeech 2 DEV & TEST: 10 hours for DEV and 10 hours for TEST per language, **transcribed by professional human annotators**, challenging and realistic.
### Annotations
#### Who are the annotators?
Development (DEV) and test (TEST) subsets are annotated by professional human annotators.
### Licensing Information
SpeechColab does not own the copyright of the audio files. For researchers and educators who wish to use the audio files for
non-commercial research and/or educational purposes, we can provide access through our site under certain conditions and terms.
In general, when training a machine learning model on a given dataset, the license of the model is **independent** to that of the
dataset. That is to say, speech recognition models trained on the GigaSpeech 2 dataset may be eligible for commercial license,
provided they abide to the 'Fair Use' terms of the underlying data and do not violate any explicit copyright restrictions.
This is likely to be true in most use-cases. However, it is your responsiblity to verify the appropriate model license for
your specific use-case by confirming that the dataset usage abides by the Fair Use terms. SpeechColab is not responsible
for the license of any machine learning model trained on the GigaSpeech 2 dataset.
