# Porjai-Thai-voice-dataset-pattani
This corpus contains a officially split of 700 hours for Central Thai, and 40 hours for the three dialect each. The corpus is designed such that there are some parallel sentences between the dialects, making it suitable for Speech and Machine translation research.

Our demo ASR model can be found at https://www.cmkl.ac.th/research/porjai. The Thai Central data was collected using [Wang Data Market](https://www.wang.in.th/).

Since parts of this corpus are in the [ML-SUPERB](https://multilingual.superbbenchmark.org/) challenge, the test sets are not released in this github and would be released subsequently in ML-SUPERB.

The baseline models of our corpus are at:

[Khummuang](https://huggingface.co/SLSCU/thai-dialect_khummuang_model)  
[Korat](https://huggingface.co/SLSCU/thai-dialect_korat_model)  
[Pattani](https://huggingface.co/SLSCU/thai-dialect_pattani_model)
