## Introduction
This is a sample from the [ORAL2013](https://wiki.korpus.cz/doku.php/en:cnk:oral2013) and [ORTOFON](https://wiki.korpus.cz/doku.php/en:cnk:ortofon) datasets, maintained by the [Czech National Corpus](https://korpus.cz/) project. The datasets were created from shared `.vert` file format using the [convert_ORTOFON_ORAL13.py](https://huggingface.co/datasets/CZLC/CNC_oral_ortofon/blob/main/convert_ORTOFON_ORAL13.py) script.

The versions of the datasets used here were downloaded from the LINDAT Clarin repository:
- [ORTOFON v1](https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-2580)
- [ORAL2013](https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-1847)

## About Original Datasets

### ORAL2013
The **ORAL2013** corpus is spoken corpus available within the framework of the Czech National Corpus project. Its aim is appropriate representation of authentic spoken language used in informal situations. The design of ORAL2013 is based on its predecessors, the informal spoken Czech corpora ORAL2006 and ORAL2008, but it includes several significant improvements, such as transcription aligned with audio, pause-based punctuation, and regional coverage of the whole Czech Republic.


### ORTOFON
The **ORTOFON** corpus captures spontaneous spoken language used in informal situations between speakers who know each other. It follows the ORAL series of informal spoken Czech corpora in its data collection design. The recordings are transcribed in two tiers - orthographic and phonetic. Together with the DIALEKT corpus, these are the first two spoken Czech corpora to have multi-tier transcription. Similar to the ORAL2013 corpus, speakers come from all over the Czech Republic and selected sociological information is collected about them.
