# 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
```
All notebooks at https://github.com/mesolitica/malaya-speech/tree/malaysian-speech/data/imda
## total lengths
1. part 1, 1117.9866586978865 hours
2. part 2, 1052.1777120312486 hours
3. part 3, 2162.4968734548597 hours
## 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. |
