## Dataset Summary
**Speech Brown** is a comprehensive, synthetic, and diverse paired speech-text dataset in 15 categories, covering a wide range of topics from fiction to religion. This dataset consists of over 55,000 sentence-level samples.
To train the [CLASP](https://huggingface.co/llm-lab/CLASP) model, we created this dataset based on the Brown Corpus. The synthetic speech was generated using the [NVIDIA Tacotron 2](https://pytorch.org/hub/nvidia_deeplearningexamples_tacotron2/) text-to-speech model.
For more information about our proposed model, please refer to this [paper](https://arxiv.org/abs/2412.13071). The dataset generation pipeline, along with code and usage instructions, is available on this [GitHub page](https://github.com/language-modeling-lab/CLASP).
## Dataset Statistics
1. Total size: Approximately 30 GB.
2. Number of samples: 55,173 pairs of speech and text.
3. Average tokens per sample: 19.00.
4. Maximum tokens in a sample: 48.
5. Average characters per sample: 96.72.
6. Number of unique tokens: 50,667
7. Categories: 15 categories consist of `adventure`, `belles_lettres`, `editorial`, `fiction`, `government`, `hobbies`, `humor`, `learned`, `lore`, `mystery`, `news`, `religion`, `reviews`, `romance`, `science_fiction`.
## Dataset Structure
To ensure ease of use, the dataset is partitioned into 10 parts. Each part can be used independently if it meets the requirements of your task and model.
### Metadata Files
1. **global_metadata**: A JSON file containing metadata for all 55,173 samples.
2. **localized_metadata**: A JSON file containing metadata for all samples, categorized into the 10 dataset partitions.
### Metadata Fields
1. **id**: The unique identifier for the sample.
2. **audio_file_path**: The file path for the audio in the dataset.
3. **category**: The category of the sample's text.
4. **text**: The corresponding text of the audio file.
## Usage Instructions
To use this dataset, download the parts and metadata files as follows:
#### Option 1: Manual Download
Visit the [dataset repository](https://huggingface.co/datasets/llm-lab/SpeechBrown/tree/main) and download all `dataset_partX.zip` files and the `global_metadata.json` file.
#### Option 2: Programmatic Download
Use the `huggingface_hub` library to download the files programmatically:
```python
from huggingface_hub import hf_hub_download
from zipfile import ZipFile
import os
import json
# Download dataset parts
zip_file_path1 = hf_hub_download(repo_id="llm-lab/SpeechBrown", filename="dataset_part1.zip", repo_type="dataset")
zip_file_path2 = hf_hub_download(repo_id="llm-lab/SpeechBrown", filename="dataset_part2.zip", repo_type="dataset")
# Download other parts...
# Download metadata
metadata_file_path = hf_hub_download(repo_id="llm-lab/SpeechBrown", filename="global_metadata.json", repo_type="dataset")
for i in range(1, 11):
with ZipFile(f'dataset_part{i}.zip', 'r') as zip_ref:
zip_ref.extractall(f'dataset_part{i}')
os.remove(f'dataset_part{i}.zip')
with open('global_metadata.json', 'r') as f:
metadata = json.load(f)
metadata.keys()
```
