# WER Evaluation Tool

This Gradio app provides a user-friendly interface for calculating Word Error Rate (WER) and related metrics between reference and hypothesis texts. It's particularly useful for evaluating speech recognition or machine translation outputs.

## Features

- Calculate WER, MER, WIL, and WIP metrics
- Text normalization options
- Custom word filtering
- Detailed error analysis
- Example inputs for testing

## How to Use

1. Enter or paste your reference text
2. Enter or paste your hypothesis text
3. Configure options (normalization, word filtering)
4. Click "Calculate WER" to see results

## Local Development

1. Clone the repository:
```bash
git clone https://github.com/yourusername/wer-evaluation-tool.git
cd wer-evaluation-tool
```

2. Create and activate a virtual environment using `uv`:
```bash
uv venv
source .venv/bin/activate  # On Unix/macOS
# or
.venv\Scripts\activate  # On Windows
```

```bash
uv pip install -r requirements.txt
```

4. Run the app locally:
```bash
uv run python app_gradio.py
```

## Installation

You can install the package directly from PyPI:

```bash
uv pip install wer-evaluation-tool
```
