## 🗂️ Estrutura do Dataset

O dataset está organizado em configs, onde cada config corresponde a um dataset ou corpora específico. Dentro de cada config, os dados estão divididos nos splits:

* `train`
* `test`
* `validation`

⚠️ **Importante**: Apenas os splits originais dos datasets foram mantidos, nem todos os datasets possuem splits de `test` e `validation`.

Cada amostra contém os seguintes campos:

* `audio_filename`: nome original do arquivo
* `speaker`: identificador do falante, presente apenas quando a informação está disponível no dataset original
* `audio`: conteúdo do áudio
* `transcription`: transcrição do áudio
* `duration`: duração em segundos

---

## 🚀 Como Utilizar

O dataset pode ser carregado pelo [🤗 Hugging Face Datasets](https://huggingface.co/docs/datasets):

### Listar todas as configurações disponíveis

```python
from datasets import get_dataset_config_names

configs = get_dataset_config_names("opedromartins/ASR-datasets-ptbr")
print(configs)
```

### Carregar uma configuração específica

```python
from datasets import load_dataset

# Exemplo: carregar todos os splits do CORAA v1.1
ds = load_dataset("opedromartins/ASR-datasets-ptbr", name="coraa-v1.1")

# Apenas o split de treino
ds_train = load_dataset("opedromartins/ASR-datasets-ptbr", name="coraa-v1.1", split="train")
```

### Uso em modo [streaming](https://huggingface.co/docs/datasets/stream)

```python
from datasets import load_dataset

ds_stream = load_dataset(
    "opedromartins/ASR-datasets-ptbr",
    name="coraa-v1.1",
    split="train",
    streaming=True
)
print(next(iter(ds_stream)))
```

## ⚖️ Licenciamento

Cada dataset mantém **sua licença original**.
É responsabilidade do usuário verificar e respeitar os termos de uso de cada corpus.
