# Google Text-to-Speech Basque sentences |
|
|
|
This dataset contains **100.000 Basque language audio files** created automatically with [Google Text-to-Speech API](https://cloud.google.com/text-to-speech/docs/apis) and sentences obtained by [Mozilla's Common Voice](https://commonvoice.mozilla.org/eu/datasets) project with Public Domain license. |
|
|
|
## Dataset Details |
|
|
|
### Dataset Description |
|
|
|
The Basque language (as it is a minorized language) has a lack of Open Data in order to train TTS models. This models need a massive quantity of recordings that nowadays nobody in the basque open-source community possibly can afford it. So, this dataset has come to fill the gap to at least start creating basic low quality artificial intelligence (AI) models. |
|
|
|
The Basque Common Voice dataset has **1017596** validated sentences in total. But, in this very first try with an objective of creating a synthetic Basque Open Source TTS, we just picked up a subset of first 100.000 sentences of the original dataset. |
|
|
|
### File structure |
|
|
|
``` |
|
common_voice_basque_dataset.zip |
|
metadata.json |
|
wav/ |
|
├─ audio_1.wav |
|
├─ audio_2.wav |
|
├─ audio_3.wav |
|
├─ audio_n.wav |
|
``` |
|
|
|
- `common_voice_basque_dataset.zip` contains 1017596 validated basque sentences used in the _**Mozilla's Common Voice**_ project. |
|
- `metadata.json` file contains audio file names with each corresponding sentence. |
|
- `wav` folder contains all audio files. |
|
|
|
### Metadata |
|
|
|
The metadata file contains the first **100.000** sentences of the `Basque Common Voice` dataset aligned with it's corresponding audio file name, following the [Piper model training recommendations](https://github.com/rhasspy/piper): |
|
|
|
``` |
|
audio_file_name|sentences |
|
``` |
|
|
|
For example the first line looks like: |
|
|
|
``` |
|
audio_1|Erloju digitala du. |
|
``` |
|
|
|
> [!NOTE] |
|
> Starting and ending spaces of the sentences from the Basque Common Voice dataset where striped before creating the audio. So, sentences from metadata.json may differ from original Common Voice sentences. |
|
|
|
> [!TIP] |
|
> The number from the filename it's exactly the line number of the `Common Voice dataset` file line number. |
|
|
|
### Audio format |
|
|
|
The audio file format choosen was a `LINEAR16`, uncompressed 16-bit signed little-endian samples (Linear PCM) with a WAV header. |
|
|
|
This choice was made because the [Piper project](https://github.com/rhasspy/piper) needs **wav** files in order to train TTS models. |
|
|
|

|
|
|
### Google TTS Voice |
|
|
|
The voice used to create these audio files is the Basque Standard B female `(eu-ES-Standard-B)` synthetic voice. There is another voice (eu-ES-Standart-A) but the quality is lower and sounds very metallic/robotic. |

## Licenses |
|
|
|
The entire Common Voice sentence dataset has a [Public Domain](https://creativecommons.org/public-domain/) license, so this Basque audio dataset does as well. |
