# 👶 Baby Cry AI Service

A Flask microservice that analyzes baby cry audio to identify the reason for crying using an ensemble of Hugging Face models.

## 🎯 Features

- **Ensemble Model Approach**: Combines supervised and zero-shot classification for improved accuracy
- **Single Load Architecture**: Models loaded once at startup for optimal performance
- **Docker Ready**: Production-ready containerized deployment
- **REST API**: Simple POST endpoint for audio analysis

## 🚀 Quick Start

### Local Development

```bash
# Install dependencies
pip install -r requirements.txt

# Run the service
python app.py
```

### Docker

```bash
# Build image
docker build -t baby-cry-ai .

# Run container
docker run -p 5000:5000 baby-cry-ai
```

## 📡 API Reference

### Health Check

```http
GET /health
```

**Response:**
```json
{
  "status": "healthy",
  "service": "baby-cry-ai"
}
```

### Analyze Cry

```http
POST /analyze-cry
Content-Type: multipart/form-data
```

**Request:**
- `audio`: Audio file (WAV, MP3, OGG, FLAC, M4A, WebM)

**Response:**
```json
{
  "cry_detected": true,
  "top_reason": "hunger",
  "scores": {
    "hunger": 0.45,
    "belly_pain": 0.20,
    "tired": 0.15,
    "discomfort": 0.12,
    "burping": 0.08
  },
  "disclaimer": "AI-generated suggestion, not a medical diagnosis. Please consult a healthcare professional for medical advice."
}
```

### Example Usage

```bash
# Using curl
curl -X POST http://localhost:5000/analyze-cry \
  -F "audio=@baby_cry.wav"

# Using Python requests
import requests

with open("baby_cry.wav", "rb") as f:
    response = requests.post(
        "http://localhost:5000/analyze-cry",
        files={"audio": f}
    )
    print(response.json())
```

## 🏷️ Cry Categories

| Label | Description |
|-------|-------------|
| `hunger` | Baby is hungry (rhythmic "neh" sound) |
| `belly_pain` | Stomach discomfort (sharp, high-pitched) |
| `tired` | Baby needs sleep (heavy, yawning cry) |
| `discomfort` | General discomfort (fussy, whiny) |
| `burping` | Needs to burp (repetitive sounds) |

## 🧠 Models Used

1. **Supervised Model**: `Wiam/baby-cry-classification-finetuned-babycry-v4`
   - Fine-tuned specifically for baby cry classification
   
2. **Zero-Shot Model**: `laion/clap-htsat-unfused`
   - CLAP model for audio-text matching
   - Provides additional context via natural language prompts

## ⚙️ Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `PORT` | `5000` | Server port |
| `FLASK_DEBUG` | `false` | Enable debug mode |

## 🔧 Production Deployment

For production, the Docker image uses Gunicorn with:
- Single worker (due to model memory requirements)
- 120s timeout for large audio files
- Health check endpoint

```bash
# Production run with custom port
docker run -p 8080:5000 -e PORT=5000 baby-cry-ai
```
