🗂️ 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:

Listar todas as configurações disponíveis

from datasets import get_dataset_config_names

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

Carregar uma configuração específica

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

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. Consulte os links das fontes listadas na tabela para mais detalhes.
