# IMDA National Speech Corpus (NSC) Speech-to-Text

Originally from https://www.imda.gov.sg/how-we-can-help/national-speech-corpus, this repository simply a mirror. This dataset associated with Singapore Open Data Licence, https://www.sla.gov.sg/newsroom/statistics/singapore-open-data-licence

We uploaded mp3 files and compressed using 7z,

```bash
7za x part1-mp3.7z.001

## Why no HuggingFace dataset format?

We had bad experiences with HuggingFace dataset format to load huge dataset. Reading mp3 files during iteration is much more faster and efficient.
