## Corpus Overview
A preprocessed version of `Switchboard Corpus`. The corpus audio has been upsampled to 16kHz, separated channels and the transcripts have been processed
with special treats for paralinguistic events, particularly laughter and speech-laughs.
This preprocessed dataset has been processed for ASR task. For the original dataset, please check out the original link: https://catalog.ldc.upenn.edu/LDC97S62 for contributed original authors. 

To download the original dataset, it can be found at:

https://drive.google.com/drive/folders/1YhpWgzCwc4cVhYJPcjuLWy84s-L0hJbf

or using `gdown`:

```bash
gdown 1YhpWgzCwc4cVhYJPcjuLWy84s-L0hJbf -O /path/to/dataset/switchboard
```

## Corpus Structure
The dataset has been splitted into train, test and validation sets with 70/20/10 ratio, as following summary:

```python
Train Dataset (70%): Dataset({
    features: ['audio', 'sampling_rate', 'transcript'],
    num_rows: 185402
})
Validation Dataset (10%): Dataset({
    features: ['audio', 'sampling_rate', 'transcript'],
    num_rows: 20601
})
Test Dataset (20%): Dataset({
    features: ['audio', 'sampling_rate', 'transcript'],
    num_rows: 51501
})
```
