+### Dataset Summary
+
+The Common Voice dataset consists of a unique MP3 and corresponding text file. 
+Many of the 31175 recorded hours in the dataset also include demographic metadata like age, sex, and accent 
+that can help improve the accuracy of speech recognition engines.
+
+The dataset currently consists of 20408 validated hours in 124 languages, but more voices and languages are always added. 
+Take a look at the [Languages](https://commonvoice.mozilla.org/en/languages) page to request a language or start contributing.
+
+You can donate to this non-profit, donation-funded project here (https://commonvoice.mozilla.org/?form=common-voice)  
+
+### Supported Tasks and Leaderboards
+
+The results for models trained on the Common Voice datasets are available via the 
+[🤗 Speech Bench](https://huggingface.co/spaces/huggingface/hf-speech-bench)
+
+### Languages

+
+## 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 Hindi config, simply specify the corresponding language config name (i.e., "hi" for Hindi):
+```python
+from datasets import load_dataset
+
+cv_17 = load_dataset("mozilla-foundation/common_voice_17_0", "hi", 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.
+```python
+from datasets import load_dataset
+
+cv_17 = load_dataset("mozilla-foundation/common_voice_17_0", "hi", split="train", streaming=True)
+
+print(next(iter(cv_17)))
+```
+
+*Bonus*: create a [PyTorch dataloader](https://huggingface.co/docs/datasets/use_with_pytorch) directly with your own datasets (local/streamed).
+
+### Local
+
+```python
+from datasets import load_dataset
+from torch.utils.data.sampler import BatchSampler, RandomSampler
+
+cv_17 = load_dataset("mozilla-foundation/common_voice_17_0", "hi", split="train")
+
+batch_sampler = BatchSampler(RandomSampler(cv_17), batch_size=32, drop_last=False)
+dataloader = DataLoader(cv_17, batch_sampler=batch_sampler)
+```
+
+### Streaming
+
+```python
+from datasets import load_dataset
+from torch.utils.data import DataLoader
+
+cv_17 = load_dataset("mozilla-foundation/common_voice_17_0", "hi", split="train")
+dataloader = DataLoader(cv_17, batch_size=32)
+```
+
+To find out more about loading and preparing audio datasets, head over to [hf.co/blog/audio-datasets](https://huggingface.co/blog/audio-datasets).
+
+### Example scripts
+
+Train your own CTC or Seq2Seq Automatic Speech Recognition models on Common Voice 16 with `transformers` - [here](https://github.com/huggingface/transformers/tree/main/examples/pytorch/speech-recognition).
+
+## 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`.
+
+```python
+{
+  'client_id': 'd59478fbc1ee646a28a3c652a119379939123784d99131b865a89f8b21c81f69276c48bd574b81267d9d1a77b83b43e6d475a6cfc79c232ddbca946ae9c7afc5', 
+  'path': 'et/clips/common_voice_et_18318995.mp3', 
+  'audio': {
+    'path': 'et/clips/common_voice_et_18318995.mp3', 
+    'array': array([-0.00048828, -0.00018311, -0.00137329, ...,  0.00079346, 0.00091553,  0.00085449], dtype=float32), 
+    'sampling_rate': 48000
+  }, 
+  'sentence': 'Tasub kokku saada inimestega, keda tunned juba ammust ajast saati.', 
+  'up_votes': 2, 
+  'down_votes': 0, 
+  'age': 'twenties', 
+  'gender': 'male', 
+  'accent': '', 
+  'locale': 'et', 
+  'segment': ''
+}
+```
+
+### Data Fields
+
+`client_id` (`string`): An id for which client (voice) made the recording
+
+`path` (`string`): The path to the audio file
+
+`audio` (`dict`): A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: `dataset[0]["audio"]` the audio file is automatically decoded and resampled to `dataset.features["audio"].sampling_rate`. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the `"audio"` column, *i.e.* `dataset[0]["audio"]` should **always** be preferred over `dataset["audio"][0]`.
+
+`sentence` (`string`): The sentence the user was prompted to speak
+
+`up_votes` (`int64`): How many upvotes the audio file has received from reviewers
+
+`down_votes` (`int64`): How many downvotes the audio file has received from reviewers
+
+`age` (`string`): The age of the speaker (e.g. `teens`, `twenties`, `fifties`)
+
+`gender` (`string`): The gender of the speaker
+
+`accent` (`string`): Accent of the speaker
+
+`locale` (`string`): The locale of the speaker
+
+`segment` (`string`): Usually an empty field
+
+### Data Splits
+
+The speech material has been subdivided into portions for dev, train, test, validated, invalidated, reported and other.
+
+The validated data is data that has been validated with reviewers and received upvotes that the data is of high quality.
+
+The invalidated data is data has been invalidated by reviewers
+and received downvotes indicating that the data is of low quality.
+
+The reported data is data that has been reported, for different reasons.
+
+The other data is data that has not yet been reviewed.
+
+The dev, test, train are all data that has been reviewed, deemed of high quality and split into dev, test and train.
+
+## Data Preprocessing Recommended by Hugging Face
+
+The following are data preprocessing steps advised by the Hugging Face team. They are accompanied by an example code snippet that shows how to put them to practice. 
+
+Many examples in this dataset have trailing quotations marks, e.g _“the cat sat on the mat.“_. These trailing quotation marks do not change the actual meaning of the sentence, and it is near impossible to infer whether a sentence is a quotation or not a quotation from audio data alone. In these cases, it is advised to strip the quotation marks, leaving: _the cat sat on the mat_.
+
+In addition, the majority of training sentences end in punctuation ( . or ? or ! ), whereas just a small proportion do not. In the dev set, **almost all** sentences end in punctuation. Thus, it is recommended to append a full-stop ( . ) to the end of the small number of training examples that do not end in punctuation.
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("mozilla-foundation/common_voice_17", "en", use_auth_token=True)
+
+def prepare_dataset(batch):
+  """Function to preprocess the dataset with the .map method"""
+  transcription = batch["sentence"]
+  
+  if transcription.startswith('"') and transcription.endswith('"'):
+    # we can remove trailing quotation marks as they do not affect the transcription
+    transcription = transcription[1:-1]
+  
+  if transcription[-1] not in [".", "?", "!"]:
+    # append a full-stop to sentences that do not end in punctuation
+    transcription = transcription + "."
+  
+  batch["sentence"] = transcription
+  
+  return batch
+
+ds = ds.map(prepare_dataset, desc="preprocess dataset")
+```
