Catalan Common Voice v17 - metadata annotated version
Dataset Summary
This version of the Catalan sentences of the Common Voice corpus (v17) includes metadata (gender and accent) for 263 speakers annotated by a team of experts.
They correspond to the speakers who have recorded more than 1200 seconds of Speech in v13.
We release these annotations (annotated_accent
and annotated_gender
fields)
along with information about the agreement among the annotators (annotated_accent_agreement
and annotated_gender_agreement
).
The overall quality of the recordings has also been annotated for these speakers (mean_quality
and stdev_quality
fields).
Additionally, since for certain users self-declared information appears only in some of their recordings (client_id
field),
we have created new columns with metadata extracted from other recordings of the same user (propagated_gender
and propagated_accents
fields).
To facilitate data analysis and classification tasks,
we have normalized the information in the free-form accents
field to the predefined list used until version 8 of the corpus (propagated_accents_norm
).
For each user, we have added the fields assigned_accent
and assigned_gender
.
For speakers annotated by the team of experts, this information is derived from their annotations.
For other speakers, we have extracted this information from their self-declared data.
See annotations for more details.
Supported Tasks and Leaderboards
Automatic Speech Recognition, Gender classification, Accent classification.
Languages
The dataset is in Catalan (ca).

Dataset Creation
Curation Rationale
During 2022, a campaign was launched to promote the Common Voice corpus within the Catalan-speaking community, achieving remarkable success. However, not all participants provided their demographic details such as age, gender, and accent. Additionally, some individuals faced difficulty in self-defining their accent using the standard classifications established by specialists.
In order to obtain a balanced corpus with reliable information, we have seen the the necessity of enlisting a group of experts from the University of Barcelona to provide accurate annotations.
We hope that this corpus will be a useful contribution to the development of ASR tasks in Catalan.
Source Data
The original data comes from the Catalan subset of the Common Voice corpus.
Initial Data Collection and Normalization
Starting with version 13 of the Common Voice corpus we identified the speakers (273) who have recorded more than 1200 seconds of speech. A team of three annotators was tasked with annotating:
- if all the recordings correspond to the same person.
- the gender of the speaker
- the accent of the speaker
- the quality of the recording
These annotations have been published in Zenodo.
They did a first round annotation, commented their different opinions and then, a second round. For this version of the corpus we used the annotations from the second round, and selected the IDs (263) where there was agreement between the annotators that correspond to a single person.
Who are the source language producers?
The original data comes from the Catalan sentences of the Common Voice corpus.
Annotations
From the original data in the Common Voice corpus the following fields have been added:
annotated_gender
(string): Annotated Gender by the experts team. It can be 'male' or 'female'annotated_gender_agreement
(float): Agreement within the annotation team about the gender of the speaker.annotated_accent
(string): Annotated Accent by the experts team. The accents considered are: Balearic, Central, Northern, Northwestern, Valencian.annotated_accent_agreement
(float): Agreement within the annotation team about the accent of the speaker.mean quality
(float): Mean annotated quality of the speakers' recording.stdev quality
(float): Deviation in the quality of annotation between annotators.propagated_gender
(string): Self-declared gender as indicated in certain recordings by the user. If there is a variation in the self-declared gender, "other" is assigned.propagated_accents
(string): Self-declared accent as indicated in certain recordings by the user. If there is variation between different accents, the majority accent is propagated.propagated_accents_normalized
(string): Propagated accent, normalized to the closed-options list used until version 7 (Balearic, Central, Northern, Northwestern, Valencian).assigned_accent
(string): Accent assigned to the speaker. If the speaker has an expert annotation, it is prioritized. Otherwise, the propagated_accents_normalized option will be chosen. If expert annotation is not available andpropagated_accents_normalized
is not available either, thevariant
option is assigned. If none of these options are assigned, the field is left empty.assigned_gender
(string): Gender assigned to the speaker. If the speaker has an expert annotation, it is prioritized. Otherwise, the propagated gender is assigned. If none of these options are assigned, the field is left empty.
Annotation process
273 speaker ID have been annotated. However, 10 of them have been discarded because they didn't correspond to a single individual.
The selected 263 speakers ID correspond to a total of 361,687 sentences in the validated split (20.18% of the total).
The full annotations made by the team of experts are available at Zenodo.
Who are the annotators?
The annotation was entrusted to the CLiC (Centre de Llenguatge i Computació) team from the University of Barcelona. They selected a group of three annotators (two men and one woman), who received a scholarship to do this work.
The annotation team was composed of:
- 2 male annotators, aged 18-25, L1 Catalan, students in the Catalan Philology degree.
- 1 female annotator, aged 18-25, L1 Catalan, student in the Modern Languages and Literatures degree, with a focus on Catalan.
- 1 female supervisor, aged 40-50, L1 Catalan, graduate in Physics and Linguistics, Ph.D. in Signal Theory and Communications.
To do the annotation they used a Google Drive spreadsheet

Considerations for Using the Data
Social Impact of Dataset

We hope that this corpus will be a useful contribution to the development of ASR tasks in Catalan
Discussion of Biases
Most of the voices of the common voice in Catalan correspond to men with a central accent between 40 and 60 years old. The aim of this dataset is to provide information that allows to minimize the biases that this could cause.
Regarding the content of the recorded sentences, we consider that the Common Voice validation system is efficient in removing those that could produce toxic content.
