# CORDI — Corpus of Dialogues in Central Kurdish
➡️ [See the repository on GitHub](https://github.com/sinaahmadi/CORDI)
This repository provides resources for language and speech technology for Central Kurdish varieties discussed in our [LREC-COLING 2024 paper](https://sinaahmadi.github.io/docs/articles/ahmadi2024cordi.pdf), particularly the first annotated corpus of spoken Central Kurdish varieties — CORDI. Given the financial burden of traditional ways of documenting languages and varieties as in fieldwork, we follow a rather novel alternative where movies and series are transcribed. Based on the cities where the content are produced, we categorize the material with the following city names:
- Sulaymaniyah. Traditionally, the variety spoken in this region is referred to as Babani (بابانی)
- Sanandaj. Traditionally, the variety spoken in this region is referred to as Ardalani (ئەردەڵانی).
- Mahabad where the Mukriyani (موکریانی) or Mukri variety is spoken
- Erbil or Hewlêr (هەولێر)
- Sardasht (سەردەشت)
- Kalar (کەلار)
CORDI contains transcriptions of 311 movies and episodes with 186,038 utterances in more than 100 hours of recording. It is openly available and can pave the way for further progress in NLP tasks for Central Kurdish varieties such as Kurdish ASR and machine translation.
More details can be found in the paper:

## Structure
CORDI available here is compatible with Hugging Face audio data format. If, instead, you prefer to use other format, please refer to the following.
The metadata of the corpus is described in [JSON](https://github.com/sinaahmadi/CORDI/blob/main/metadata.json) and [TSV](https://github.com/sinaahmadi/CORDI/blob/main/metadata.tsv) with the following information:
```json
{
"CORDI": {
"2": {
"Dialect": "Silêmanî",
"Title_ckb_arab": "بەرنامەی بەرنامە",
"Title_ckb_latn": "Bernamey bername",
"Episode": "1",
"Episode_ckb_arab": "عەرەبانەکە",
"Episode_ckb_latn": "`Erebaneke",
"Type": "Theatre show",
"Genre": "Comedy",
"is_synched": true,
"Comment": "",
"text": "content/text_original/2.srt",
"audio": "content/audio/2.wav",
"video": "content/video/2.mp4"
}
}
}
```
Each entry in the metadata file points to a movie or episode which is itself described as follows:
```json
{
"filename": "2",
"utterance_ID": "2",
"gender": "F",
"age": "A",
"text": "وەڵا مەخۆ وەڵا ناوی گرانە ئە ئەمە کەی کوولەکەی خۆمانە",
"audio": "content/segments/2/2.ogg",
"dialect": "Silêmanî"
}
```

- [Transcriptions](https://drive.google.com/file/d/1giQbsc3t1kE6nI6HNtW7_hi5BEKFgfJp/view?usp=sharing) (5MB): subtitles in `.srt`.
- [Transcriptions in JSON](https://github.com/sinaahmadi/CORDI/blob/main/content/CORDI_text_json.zip) (8MB): the JSON files of the movies and series, individually.
Text + audio:
- [Segments](https://drive.google.com/file/d/1LKSZas4ckFoMDajTjxDIL5BrjLm_6B7J/view?usp=sharing) (4GB) contains utterances in audio (`.ogg`) and their transcriptions in JSON. This can be used for ASR.
In case you want to work on the original material, you can find the videos here: [link](https://drive.google.com/file/d/1zKw91ogEFbDtQUVjUfzioAt7ZEY3W3JL/view?usp=sharing) (27GB).
## Downstream tasks
In addition to the corpus, we focus on three downstream tasks in this project: automatic speech recognition (ASR), machine translation (MT) and language identification (LID). While the details of the ASR systems are described in [the paper](https://sinaahmadi.github.io/docs/articles/ahmadi2024cordi.pdf), more details can be found about the two other tasks in their folders:
- [Machine translation](https://github.com/sinaahmadi/CORDI/tree/main/MT)
- [Language Identification](https://github.com/sinaahmadi/CORDI/tree/main/LID)
## Report problems
Given the size of the projects, it is totally possible that some utterances are not synchronized correctly. We currently don't have much time to each them manually. However, if you notice any serious problem, please consider reporting (in issues) or correct them. We also appreciate any efforts to further clean the transcriptions.

## Acknowledgements
We express our heartfelt gratitude to the volunteers at Koya University who actively participated in the transcription and annotation tasks spanning a period of ten months from June 2021 to April 2022.
