# Wikipedia Utterances

Text segments extracted from English Wikipedia, segmented into utterance-length chunks suitable for text-to-speech synthesis.

## Dataset Description

This dataset contains ~41M text utterances derived from the [wikimedia/wikipedia](https://huggingface.co/datasets/wikimedia/wikipedia) dataset (20231101.en snapshot). Each row contains:

| Field | Type | Description |
|-------|------|-------------|
| `title` | string | The Wikipedia article title |
| `text` | string | A text segment (10-4,880 characters) |
| `duration` | float | Estimated speech duration in seconds (at 150 WPM) |

## Processing

The transformation pipeline:

1. Tokenizes Wikipedia articles into paragraphs and sentences using NLTK
2. Combines consecutive sentences targeting 15-30 second utterances
3. Strips bracketed content (parentheses, braces, square brackets)
4. Filters for valid utterances ending in sentence-final punctuation

See `transform_wikipedia.py` in this repository for the full implementation.

## Usage

```python
from datasets import load_dataset

dataset = load_dataset("jspaulsen/wikipedia-utterances", split="train")
```
