# Mumospee V2: A MUltiMOdal SPEEch Corpus Version 2
## Dataset Description
**MuMoSPEE v2** is a large-scale multimodal speech dataset containing **audio and video recordings with transcripts**, aggregated from:
1. **European Council events** — official speeches, interviews, and doorstep appearances.
2. **Public YouTube meetings** — webinars, conferences, panel discussions, and institutional videos.
This release is built upon the **first version of the MuMoSPEE dataset**, significantly expanding both the **scale** and **diversity** of content, and unifying audio and video data into a consistent metadata format suitable for large-scale speech and multimodal research.
The original MuMoSPEE v1 dataset is available at:
👉 **https://huggingface.co/datasets/meetween/mumospee**
The dataset is designed for research in **speech recognition, multimodal modeling, meeting analysis, and AI-driven content understanding**.
All media are linked via URLs, with transcripts and metadata included. Audio and video recordings are stored as separate entries.

- **Notes**
For recordings containing multiple spoken languages, the total duration is **split equally among the detected languages**, as precise language-level timestamps are not available. This avoids inflating the total duration across languages.
## Notes on Transcripts
- **EU Council (audio & video):**
Transcripts are generated using the **Whisper ASR package**. Each entry contains **one or more languages** per recording, corresponding to the full speech.
- **YouTube Meeting (video):**
Transcripts are extracted from YouTube subtitle tracks. They may be **auto-generated**, and some videos may **lack transcripts entirely**.

## Usage
```python
from datasets import load_dataset
dataset = load_dataset("meetween/mumospee_v2")
# Access first audio sample
audio_sample = dataset['train'].filter(lambda x: x['type'] == 'audio')[0]
print(audio_sample['transcript'])
print(audio_sample['url'])
# Access first video sample
video_sample = dataset['train'].filter(lambda x: x['type'] == 'video')[0]
print(video_sample['transcript'])
print(video_sample['url'])
```
