# DoReCo Southern England
[DoReCo](https://doreco.huma-num.fr/) (Language DOcumentation REference COrpus) contains 100 hours of speech across 53 languages.
It contains phonemic annotations using the sounds supported by [X-SAMPA](https://en.wikipedia.org/wiki/X-SAMPA).
You can read more about the Southern England portion [here](https://doreco.huma-num.fr/languages/sout3282). 
It was compiled by Nils Norman Schiborr and further processed by Ludger Paschen and Matthew Stave.

## 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/DoReCo.py).
This maps the 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 split up the longer narrative recordings into shorter self-contained clips based on semantic content and remove unintelligible utterances with less than 11 phonemes.

- The dataset has 577 samples (around 47 minutes of speech).

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