Dataset Summary

This repository contains subsets of the SpokesMix (SpokesMix, SpokesBiz and Diabiz) corpora processed in the format of the BIGOS (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 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.

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.
The audio and metadata can be used in a raw format (TSV) or via the hugging face datasets library.
References for the test split will only become available after the completion of the 2024 PolEval challenge.

Data Instances

Data Fields

Available fields:

audioname - file identifier
split - test, validation or train split
dataset - source dataset identifier
audio - HF dataset object with binary representation of audio file
ref_orig - original transcription of audio file
samplingrate_orig - sampling rate of the original recording
sampling_rate - sampling rate of recording in the release
audio_duration_samples - duration of recordings in samples
audio_duration_seconds - duration of recordings in seconds
audiopath_bigos - relative filepath to audio file extracted from tar.gz archive
audiopath_local - absolute filepath to audio file extracted with the build script
speaker_sex - sex of the speaker extracted from the source meta-data (N/A if not available)
speaker_age - age group of the speaker (in CommonVoice format) extracted from the source (N/A if not available)

Data Splits

Train split contains recordings intendend for training. Validation split contains recordings for validation during training procedure. Test split contains recordings intended for evaluation only. References for test split are not available until the completion of 2024 PolEval challenge.

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 corpus
SpokesBiz corpus.
PolEval DiaBiz sample corpus.

Initial Data Collection and Normalization

Source text and audio files were extracted and encoded in a unified format.
Original dataset-specific transcription norms are preserved, including punctuation and casing.

Who are the source language producers?

The PELCRA SpokesMix, SpokesBiz and DiaBiz datasets were created by:
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.

The curation and inclusion of subsets of these corpora into the BIGOS format was done by Michał Junczyk from Adam Mickiewicz University.

Annotations

Annotation process

Current release contains original, manually performed transcriptions.

Who are the annotators?

Participants of the original projects.

Personal and Sensitive Information

This corpus does not contain PII or Sensitive Information. All IDs of speakers are anonymized.

Considerations for Using the Data

Social Impact of Dataset

To be updated.

Discussion of Biases

To be updated.

Other Known Limitations

Some metadata avaiable in the original releases is not available in the initial HF release e.g. speaker age, sex etc.
