# Composite dataset for Basque made from public available data
This dataset is composed of the following public available data:
## Train split:
The train split is composed of the following datasets combined:
- **mozilla-foundation/common_voice_18_0/eu**: "validated" split removing "test_cv" and "dev_cv" split's sentences. (validated split contains official train + dev + test splits and more unique data)
- **gttsehu/basque_parliament_1/eu**: "train_clean" split removing some of the sentences that are repeated in "test_parl" and "dev_parl" splits (not the same recording but same text).
- **openslr**: a train split made from the SLR76 (Basque recordings) subset, this split has been cleaned from acronyms, numbers and sentences that are repeated in the following "test_oslr" and "dev_oslr" splits.
| Split tag | Source | Hours | Sentences |
|:---------:|:--------------------:|:------------:|:----------:|
| - | common_voice_18_0 | 300.05 h | 198498 |
| - | basque_parliament_1 | 369.65 h | 185699 |
| - | openslr | 6.28 h | 3229 |
| train | **Total** | **675.98 h** | **387426** |
## Test splits:
Those test splits are separated, and it is recommended to not evaluate them together in a single split:
- **mozilla-foundation/common_voice_18_0/eu**: official "test" split.
- **gttsehu/basque_parliament_1/eu**: official "test" split.
- **openslr**: a test split made from the SLR76 (Basque recordings) subset, this split has been cleaned from acronyms, numbers and repeated sentences so all of them are only once in the split.
| Split tag | Source | Hours | Sentences |
|:---------:|:--------------------:|:------------:|:----------:|
| test_cv | common_voice_18_0 | 24.2 h | 14312 |
| test_parl | basque_parliament_1 | 2.85 h | 1521 |
| test_oslr | openslr | 1.03 h | 526 |
| | **Total** | **28.08 h** | **16359** |
## Dev splits:
Theres a dev split composed by 3 dev subsplits that are also independently accesible. It is recommended to use the combined "dev" split for development tasks since it is accurately balanced in number of hours.
- **mozilla-foundation/common_voice_18_0/eu**: a small dev split made from the official "dev" split.
- **gttsehu/basque_parliament_1/eu**: a small dev split made from the official "dev" split.
- **openslr**: a dev split made from the SLR76 (Basque recordings) subset, this split has been cleaned from acronyms, numbers and repeated sentences so all of them are only once in the split.
| Split tag | Source | Hours | Sentences |
|:---------:|:--------------------:|:------------:|:----------:|
| dev_cv | common_voice_18_0 | 1.02 h | 620 |
| dev_parl | basque_parliament_1 | 1.01 h | 550 |
| dev_oslr | openslr | 1.01 h | 521 |
| dev | **Total** | **3.04 h** | **1691** |
