# WenetSpeech
## Overview
WenetSpeech is a large-scale Mandarin Chinese speech corpus with over 10,000 hours of multi-domain transcribed audio data, designed for speech recognition research.
## Task Description
- **Task Type**: Automatic Speech Recognition (ASR)
- **Input**: Audio recordings with Mandarin Chinese speech
- **Output**: Transcribed text in Chinese
- **Domain**: Multi-domain (internet, meeting)
## Key Features
- Large-scale Mandarin Chinese speech corpus (10,000+ hours)
- Multi-domain coverage: internet content, meetings
- High-quality transcriptions
- Suitable for evaluating Chinese ASR systems
- Supports mixed Chinese-English text evaluation
## Evaluation Notes
- Default configuration uses **test_meeting** split
- Subsets by domain: **dev** (development), **test_meeting** (meeting domain)
- Primary metric: **MER** (Mixed Error Rate)
- MER tokenizes Chinese characters individually and English words as whole tokens
- Prompt: "Please listen to the audio and transcribe what you hear"

## Usage
### Using CLI
```bash
evalscope eval \
--model YOUR_MODEL \
--api-url OPENAI_API_COMPAT_URL \
--api-key EMPTY_TOKEN \
--datasets wenet_speech \
--limit 10 # Remove this line for formal evaluation
```
### Using Python
```python
from evalscope import run_task
from evalscope.config import TaskConfig
task_cfg = TaskConfig(
model='YOUR_MODEL',
api_url='OPENAI_API_COMPAT_URL',
api_key='EMPTY_TOKEN',
datasets=['wenet_speech'],
dataset_args={
'wenet_speech': {
# subset_list: ['dev', 'test_meeting'] # optional, evaluate specific subsets
}
},
limit=10, # Remove this line for formal evaluation
)
run_task(task_cfg=task_cfg)
```
