## Dataset Description

- **Repository:** https://github.com/SpeechColab/GigaSpeech2
- **Paper:** TODO:

## 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. The most common evaluation metric is the word error rate (WER). The task has an active leaderboard which can be found at https://github.com/SpeechColab/GigaSpeech#leaderboard and ranks models based on their WER.
- `text-to-speech`, `text-to-audio`: The dataset can also be used to train a model for Text-To-Speech (TTS).

### Languages

Gigaspeech contains audio and transcription data in Thai, Indonesian, Vietnamese.

### 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 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 dataset.
