# OLaPh Phonemization Dataset

## Dataset Summary
This dataset was created with the [OLaPh framework](https://github.com/iisys-hof/olaph) and used to train the [OLaPh grapheme-to-phoneme model](https://huggingface.co/iisys-hof/olaph). It contains multilingual text from the FineWeb datasets, automatically phonemized into text–phoneme pairs for English, German, French, and Spanish.

## Source Data
Text was taken from:
- [HuggingFaceFW/fineweb](https://huggingface.co/datasets/HuggingFaceFW/fineweb)
- [HuggingFaceFW/fineweb-2](https://huggingface.co/datasets/HuggingFaceFW/fineweb-2)

## Phonemization
All text was processed and phonemized automatically using the [**OLaPh framework**](https://github.com/iisys-hof/olaph).

## Intended Use
This dataset is intended for research and development of phonemization models, and related speech or linguistic tasks.
