+# Dataset Card for Common Voice Corpus 15.0
+
+<!-- Provide a quick summary of the dataset. -->
+
+This dataset is an unofficial converted version of the Mozilla Common Voice Corpus 15. It currently contains the following languages: Portuguese 
+
+
+
+## How to use
+The datasets library allows you to load and pre-process your dataset in pure Python, at scale. The dataset can be downloaded and prepared in one call to your local drive by using the load_dataset function.
+
+For example, to download the Portuguese config, simply specify the corresponding language config name (i.e., "pt" for Portuguese):
+```
+from datasets import load_dataset
+
+cv_15 = load_dataset("fsicoli/common_voice_15_0", "pt", split="train")
+```
+Using the datasets library, you can also stream the dataset on-the-fly by adding a streaming=True argument to the load_dataset function call. Loading a dataset in streaming mode loads individual samples of the dataset at a time, rather than downloading the entire dataset to disk.
+
+```
+from datasets import load_dataset
+
+cv_15 = load_dataset("fsicoli/common_voice_15_0", "pt", split="train", streaming=True)
+
+print(next(iter(cv_15)))
+```
+
+Bonus: create a PyTorch dataloader directly with your own datasets (local/streamed).
+
+### Local
+```
+from datasets import load_dataset
+from torch.utils.data.sampler import BatchSampler, RandomSampler
+
+cv_15 = load_dataset("fsicoli/common_voice_15_0", "pt", split="train")
+batch_sampler = BatchSampler(RandomSampler(cv_15), batch_size=32, drop_last=False)
+dataloader = DataLoader(cv_15, batch_sampler=batch_sampler)
+```
+
+### Streaming
+```
+from datasets import load_dataset
+from torch.utils.data import DataLoader
+
+cv_15 = load_dataset("fsicoli/common_voice_15_0", "pt", split="train")
+dataloader = DataLoader(cv_15, batch_size=32)
+```

+### Dataset Structure
+Data Instances
+A typical data point comprises the path to the audio file and its sentence. Additional fields include accent, age, client_id, up_votes, down_votes, gender, locale and segment.
