# Indian Emotional Speech Corpus

## Dataset Description

This dataset comprises high-quality audio recordings of Indian speakers reading a standardized 50-word paragraph in four distinct emotional tones — **happy**, **sad**, **surprised**, and **angry**.

Each recording is approximately 20–25 seconds long and includes the full paragraph with tone shifts at specific points.

**Text spoken by all participants:**

> (happy tone) *Last Monday was perfect—I got the job I’d been dreaming of! I screamed, hugged my parents, and we even had cake for breakfast.*  
> (sad tone) *But two days later, my mom called—our dog Bruno had passed away in his sleep. I didn’t even get to say goodbye.*  
> (surprised tone) *And just when I thought the week couldn’t get any crazier, I got a surprise call—I was selected for a global fellowship I never even applied for!*  
> (angry tone) *But earlier that day, my Wi-Fi cut out again during an important meeting... third time this week! It’s beyond frustrating. What a week. Honestly, I’m still processing it all.*

The dataset supports training and evaluation of models in:

- Automatic Speech Recognition (ASR)
- Emotional tone classification
- Voice synthesis and generation
- Emotion-aware conversational agents

## Dataset Structure

- **Audio Files**: Audio clips are stored in the `audio/` directory with names like `audio_001.wav`, `audio_002.mp3`, etc.
- **Formats**: `.wav`, `.mp3`, `.m4a`
- **Duration**: Each file is 20–25 seconds long

- **Metadata** (in `metadata.csv`):
  - `file_name`: Name of the audio file
  - `transcription`: Full 50-word paragraph
  - `emotional_tones`: Order of tones (e.g., `happy;sad;surprised;angry`)
  - `age_group`: e.g., `18–30`, `31–45`, `46–60`
  - `gender`: `male` or `female`
  - `region`: e.g., `North India`, `South India`, `East India`, `West India`

## Intended Uses

### ✅ Direct Use

- Training and benchmarking ASR models with Indian-accented English
- Emotion detection and classification from voice
- Research in affective computing and empathetic AI

### ❌ Out-of-Scope Use

- Real-time or production-grade systems
- Commercial use without proper CC BY 4.0 attribution
- Clinical or diagnostic use cases

## Considerations and Limitations

- ❗ The dataset is small (<1,000 samples) and not fully representative of India's linguistic and emotional diversity
- 💡 Emotions are subjective — classification results may vary by listener or model
- 🔄 Future versions will aim to expand multilingual support and speaker diversity
