# Condensed LibriSpeech ASR

This dataset is a condensed version of the [LibriSpeech ASR dataset](https://huggingface.co/datasets/openslr/librispeech_asr), created by subsampling approximately 10% of the original data from each split. It is intended for quick experimentation, prototyping, and debugging when working with Automatic Speech Recognition (ASR) tasks.

## Dataset Details

- **Original Dataset:** [LibriSpeech ASR](https://huggingface.co/datasets/openslr/librispeech_asr)
- **Condensation Ratio:** Approximately 10% of the full dataset
- **Splits Included:**
  - `train.clean.100`
  - `train.clean.360`
  - `train.other.500`
  - `validation.clean`
  - `validation.other`
  - `test.clean`
  - `test.other`

For each split, a default number of examples was extracted:
- **Training Splits:** 1,000 examples each
- **Validation/Test Splits:** 100 examples each

## Data Format

Each sample in the dataset contains the following fields:

- **file:**  
  A path to the original audio file (FLAC format).

- **audio:**  
  A dictionary containing:
  - `path`: Path to the audio file.
  - `array`: The decoded audio waveform as a NumPy array.
  - `sampling_rate`: The sampling rate (typically 16 kHz).

- **text:**  
  The transcription corresponding to the audio.

- **id:**  
  A unique identifier for the sample.

- **speaker_id:**  
  A unique identifier for the speaker.

- **chapter_id:**  
  An identifier corresponding to the audiobook chapter.

## How Was This Dataset Created?

The condensed dataset was generated by streaming the full [LibriSpeech ASR dataset](https://huggingface.co/datasets/openslr/librispeech_asr) using the Hugging Face Datasets library and selecting approximately 10% of each split. This process preserves the original structure and fields, enabling seamless use with models and workflows designed for LibriSpeech.

## Usage Example

Below is a Python snippet to load and inspect the dataset:

```python
from datasets import load_dataset

# Load the condensed dataset from the Hugging Face Hub
dataset = load_dataset("nyalpatel/condensed_librispeech_asr")

# Access a specific split (e.g., test.clean)
test_dataset = dataset["test.clean"]

# Display the first example in the test set
print(test_dataset[0])
