### Dataset Summary
|
66 |
+
|
67 |
+
This version of the [Catalan sentences of the Common Voice corpus (v17)](https://commonvoice.mozilla.org/en/datasets)
|
68 |
+
includes metadata (gender and accent) for 263 speakers annotated by a team of experts.
|
69 |
+
|
70 |
+
They correspond to the speakers who have recorded more than 1200 seconds of Speech in [v13](https://huggingface.co/datasets/mozilla-foundation/common_voice_13_0/tree/main/transcript/ca).
|
71 |
+
|
72 |
+
We release these annotations (``annotated_accent`` and ``annotated_gender`` fields)
|
73 |
+
along with information about the agreement among the annotators (``annotated_accent_agreement`` and ``annotated_gender_agreement``).
|
74 |
+
|
75 |
+
The overall quality of the recordings has also been annotated for these speakers (``mean_quality`` and ``stdev_quality`` fields).
|
76 |
+
|
77 |
+
Additionally, since for certain users self-declared information appears only in some of their recordings (``client_id`` field),
|
78 |
+
we have created new columns with metadata extracted from other recordings of the same user (``propagated_gender`` and ``propagated_accents`` fields).
|
79 |
+
|
80 |
+
To facilitate data analysis and classification tasks,
|
81 |
+
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``).
|
82 |
+
For each user, we have added the fields ``assigned_accent`` and ``assigned_gender``.
|
83 |
+
For speakers annotated by the team of experts, this information is derived from their annotations.
|
84 |
+
For other speakers, we have extracted this information from their self-declared data.
|
85 |
+
See [annotations](#annotations) for more details.

## Dataset Creation
|
197 |
+
|
198 |
+
### Curation Rationale
|
199 |
+
|
200 |
+
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.
|
201 |
+
|
202 |
+
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.
|
203 |
+
|
204 |
+
We hope that this corpus will be a useful contribution to the development of ASR tasks in Catalan.
|
205 |
+
|
206 |
+
### Source Data
|
207 |
+
|
208 |
+
The original data comes from the [Catalan subset of the Common Voice corpus](https://commonvoice.mozilla.org/en/datasets).
|
209 |
+
|
210 |
+
#### Initial Data Collection and Normalization
|
211 |
+
|
212 |
+
Starting with [version 13 of the Common Voice corpus](https://commonvoice.mozilla.org/en/datasets) we identified the speakers (273) who have recorded more than 1200 seconds of speech.
|
213 |
+
A team of three annotators was tasked with annotating:
|
214 |
+
- if all the recordings correspond to the same person.
|
215 |
+
- the gender of the speaker
|
216 |
+
- the accent of the speaker
|
217 |
+
- the quality of the recording
|
218 |
+
These annotations have been published in [Zenodo](link).
|
219 |
+
|
220 |
+
They did a first round annotation, commented their different opinions and then, a second round.
|
221 |
+
For this version of the corpus we used the annotations from the second round,
|
222 |
+
and selected the IDs (263) where there was agreement between the annotators that correspond to a single person.
|
223 |
+
|
224 |
+
#### Who are the source language producers?
|
225 |
+
|
226 |
+
The original data comes from the [Catalan sentences of the Common Voice corpus](https://huggingface.co/datasets/mozilla-foundation/common_voice_16_1/tree/main/transcript/ca).
|
227 |
+
|
228 |
+
### Annotations
|
229 |
+
|
230 |
+
From the original data in the [Common Voice corpus](https://huggingface.co/datasets/mozilla-foundation/common_voice_13_0/tree/main/transcript/ca)
|
231 |
+
the following fields have been added:
|
232 |
+
|
233 |
+
- `annotated_gender`(string): Annotated Gender by the experts team. It can be 'male' or 'female'
|
234 |
+
|
235 |
+
- `annotated_gender_agreement` (float): Agreement within the annotation team about the gender of the speaker.
|
236 |
+
|

245 |
+
- `propagated_gender` (string): Self-declared gender as indicated in certain recordings by the user.
|
246 |
+
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.
|
249 |

255 |
+
Otherwise, the propagated_accents_normalized option will be chosen.
|
256 |
+
If expert annotation is not available and ``propagated_accents_normalized`` is not available either, the ``variant`` option is assigned.

#### Annotation process
|
265 |
+
|
266 |
+
273 speaker ID have been annotated. However, 10 of them have been discarded because they didn't correspond to a single individual.
|
267 |
+
|
268 |
+
The selected 263 speakers ID correspond to a total of 361,687 sentences in the validated split (20.18% of the total).
|
269 |
+
|
270 |
+
The full annotations made by the team of experts are available at [Zenodo](link).
|
271 |
+
|
272 |
+
#### Who are the annotators?
|
273 |
+
|
274 |
+
The annotation was entrusted to the [CLiC (Centre de Llenguatge i Computaci贸)](https://clic.ub.edu/en/que-es-clic) team from the University of Barcelona.
|
275 |
+
They selected a group of three annotators (two men and one woman), who received a scholarship to do this work.
|
276 |
+
|
277 |
+
The annotation team was composed of:
|
278 |
+
|
279 |
+
* 2 male annotators, aged 18-25, L1 Catalan, students in the Catalan Philology degree.
|
280 |
+
* 1 female annotator, aged 18-25, L1 Catalan, student in the Modern Languages and Literatures degree, with a focus on Catalan.
|
281 |
+
* 1 female supervisor, aged 40-50, L1 Catalan, graduate in Physics and Linguistics, Ph.D. in Signal Theory and Communications.
|
282 |
+
|
283 |
+
To do the annotation they used a Google Drive spreadsheet

### Personal and Sensitive Information
|
286 |
+
|
287 |
+
The dataset consists of people who have donated their voice online. You agree to not attempt to determine the identity of speakers in the Common Voice dataset.

## Considerations for Using the Data

### Social Impact of Dataset
|
292 |
+
|
293 |
+
The dataset consists of people who have donated their voice online.
|
294 |
+
You agree to not attempt to determine the identity of speakers in the Common Voice dataset.
|
295 |
+
|
296 |
+
We hope that this corpus will be a useful contribution to the development of ASR tasks in Catalan

### Discussion of Biases
|
299 |
+
|
300 |
+
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.
|
301 |
+
|
302 |
+
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.
