### Dataset Summary
This repository contains subsets of the SpokesMix ([SpokesMix](http://docs.pelcra.pl/doku.php?id=spokes_documentation), [SpokesBiz](http://docs.pelcra.pl/doku.php?id=spokesbiz) and [Diabiz](http://docs.pelcra.pl/doku.php?id=diabiz)) corpora 
processed in the format of the [BIGOS](https://huggingface.co/datasets/amu-cai/pl-asr-bigos-v2) (Benchmark Intended Grouping of Open Speech) format.
The main contribution of these corpora are a) spontaneous and conversional speech and b) phone-based customer interactions.
The inclusion of the subsets in the [BIGOS](https://huggingface.co/datasets/amu-cai/pl-asr-bigos-v2) corpora, will hopefully result in 
the most comprehensive publicly available evaluation of Polish ASR systems in terms of number of speakers, devices and acoustic conditions.
Further contributions to the benchmark datasets from the community are highly welcomed.
<br>

### Supported Tasks and Leaderboards
The PELCRA test sets are intented for benchmarking Polish ASR systems under the 2024 PolEval challenge.

### Languages
Polish

## Dataset Structure
The datasets consist of audio recordings in the WAV format with corresponding metadata.<br>
The audio and metadata can be used in a raw format (TSV) or via the hugging face datasets library.<br>
References for the test split will only become available after the completion of the 2024 PolEval challenge.<br>

## Dataset Creation

### Curation Rationale
The dataset was curated in order to enable convenient use of training, validation and test corpora across all publically available ASR speech datasets for Polish. Thanks to similar format of PELCRA and BIGOS corpora and convenient access via hugging face platform ASR practioners are able to leverage vast amount of diverse set of recordings with reduced overhead.
Recordings which either lacked transcriptions or were too short to be useful for training or evaluation were removed during curation.

### Source Data
Data was sourced from the below original datasets with the original authors' permission:
* [SpokesMix](http://docs.pelcra.pl/doku.php?id=spoken_offline_corpora) corpus
* [SpokesBiz](http://docs.pelcra.pl/doku.php?id=spokesbiz") corpus.
* [PolEval DiaBiz sample](http://docs.pelcra.pl/doku.php?id=diabiz) corpus.

#### Initial Data Collection and Normalization
Source text and audio files were extracted and encoded in a unified format.<br>
Original dataset-specific transcription norms are preserved, including punctuation and casing. <br>

#### Who are the source language producers?
The PELCRA SpokesMix, SpokesBiz and DiaBiz datasets were created by:<br>
Piotr Pęzik, Michał Adamczyk, Małgorzata Krawentek, Paweł Wilk, Sylwia Karasińska, Angelika Peljak-Łapińska, Karolina Adamczyk, Monika Garnys, Karolina Walkusz, Anna Cichosz, Anna Kwiatkowska, Mikołaj Deckert, Paulina Rybińska, Izabela Grabarczyk, Maciej Grabski, Karol Ługowski, Michał Koźmiński, Zuzanna Deckert, Piotr Górniak, Konrad Kaczyński, Łukasz Jałowiecki and others. <br>

The corpus was developed to boost the development of third-party speech recognition engines, dialog systems and conversational intelligence tools for Polish. Its current size amounts to nearly 410 hours of recordings and over 3 million words of transcribed speech. We present the structure of the corpus, data collection and transcription procedures, challenges of punctuating and truecasing speech transcripts, dialog structure annotation and discuss some of the ecological validity considerations involved in the development of such resources.},
