# ScreenTalk_JA2ZH-XS

**ScreenTalk_JA2ZH-XS** is a paired dataset of **Japanese speech and Chinese translated text** released by DataLabX. It is designed for training and evaluating speech translation (ST) and multilingual speech understanding models. The data consists of spoken dialogue extracted from real-world Japanese movies and TV shows.

## 📦 Dataset Overview

- **Source Language**: Japanese (Audio)
- **Target Language**: Simplified Chinese (Text)
- **Number of Samples**: 10,000
- **Total Duration**: ~30 hours
- **Format**: Parquet
- **License**: CC BY 4.0
- **Tasks**:
  - Speech-to-Text Translation (ST)
  - Multilingual ASR+MT joint modeling
  - Japanese ASR with Chinese aligned text training

## 📁 Data Fields

| Field Name  | Type     | Description                                |
|-------------|----------|--------------------------------------------|
| `audio`     | `Audio`  | Raw Japanese speech audio clip             |
| `sentence`  | `string` | Corresponding **Simplified Chinese text**  |
| `duration`  | `float`  | Duration of the audio in seconds          |
| `uid`       | `string` | Unique sample identifier                   |
| `group_id`  | `string` | Grouping ID (e.g., speaker or scene tag)   |

## 🔍 Example Samples

| audio       | Duration (s)  | sentence                        |
|-----------|---------------|--------------------------------------------|
| JA_00012  | 4.21          | 他不会来了。                              |
| JA_00038  | 6.78          | 为什么你会这样说？告诉我真相。              |
| JA_00104  | 3.33          | 安静，有人来了。                            |

## 💡 Use Cases

This dataset is ideal for:

- 🎯 Training **speech translation models**, such as [Whisper ST](https://huggingface.co/docs/transformers/main/en/model_doc/whisper#speech-translation)
- 🧪 Research on **multilingual speech understanding**
- 🧠 Developing multimodal AI systems (audio → Chinese text)
- 🏫 Educational tools for Japanese learners

## 📥 Loading Example (Hugging Face Datasets)

```python
from datasets import load_dataset

ds = load_dataset("DataLabX/ScreenTalk_JA2ZH-XS", split="train")
```
