# EpaDB
EpaDB is a speech database of 50 native Spanish speakers (25 male, 25 female) from Argentina speaking English.
It contains phonemic annotations using mainly the sounds supported by [ARPABet](https://en.wikipedia.org/wiki/ARPABET) with a few extensions to model Spanish influenced dialects of English.
It was developed by Jazmin Vidal, Luciana Ferrer, and Leonardo Brambilla at the [Speech Lab](http://habla.dc.uba.ar/). Read more on their [official github](https://github.com/JazminVidal/EpaDB) and [paper](https://github.com/JazminVidal/EpaDB/blob/master/EpaDB%20-%20Paper.pdf).

## This Processed Version
We have processed the dataset into an easily consumable [Hugging Face dataset](https://huggingface.co/docs/datasets/en/index) using [this data processing script](https://github.com/KoelLabs/ML/blob/main/scripts/data_loaders/EpaDB.py).
This maps the EpaDB phoneme annotations to [IPA](https://en.wikipedia.org/wiki/International_Phonetic_Alphabet) as supported by libraries like [ipapy](https://pypi.org/project/ipapy/0.0.1.0/) and [panphon](https://pypi.org/project/panphon/0.5/).
We also correct the occasional typos or formatting inconsistencies.

- The train set has 1894 samples (around 98 minutes of speech).
- The test set has 1266 samples (around 66 minutes of speech).

All audio has been converted to float32 in the -1 to 1 range at 16 kHz sampling rate.
