# Integration-Armour: Financial Audio Intelligence System

**A comprehensive AI system for processing multilingual financial inquiries with advanced NLP, ASR, and financial entity extraction.**

## Overview

Integration-Armour is a production-ready backend system designed for financial institutions to process customer inquiries in **Hindi, Hinglish (Hindi-English code-mixed), and English**. It combines:

- 🎙️ **Advanced Speech Recognition** (Whisper, indicwav2vec)
- 🌍 **Multilingual NLP** (Language detection, code-mixing handling)
- 💰 **Financial Entity Extraction** (Amounts, instruments, decisions)
- 🎯 **Intent Classification** (Loan requests, investments, complaints)
- 💪 **Confidence Scoring** (Quality-aware processing)

## Models Included

### 1. **Finance Classifier** (`finance_classifier/`)
- **Purpose**: Intent classification for financial queries
- **Supported Intents**: 
  - Loan Application
  - Investment Query
  - Account Inquiry
  - Complaint Registration
  - General Support
- **Languages**: Hindi, Hinglish, English
- **Model Type**: Transformer-based (DistilBERT)
- **Size**: 711MB

### 2. **Finance NER** (`finance_ner/`)
- **Purpose**: Named Entity Recognition for financial information
- **Entities Extracted**:
  - `AMOUNT`: Loan amounts, investment amounts
  - `INSTRUMENT`: Loan types, investment products
  - `DURATION`: Tenure, timeline
  - `PERSON`: Customer names, references
  - `ORGANIZATION`: Bank names, company names
- **Model Type**: Token classification (BERT-based)
- **Size**: 709MB

## System Architecture

```
Audio Input → Language Detection → ASR → NLP Pipeline → Insights
                                          ├→ Classification
                                          ├→ NER
                                          ├→ Sentiment
                                          └→ Confidence Scoring
```

## Key Features

### ✅ Multilingual Support
- Hindi (Devanagari script)
- Hinglish (code-mixed Hindi-English)
- English
- Tamil, Telugu, Marathi (ready for expansion)

### ✅ Hindi/Urdu Differentiation
- Script-based detection (Devanagari vs Persian-Arabic)
- Resolves Whisper's language confusion
- Automatically flags code-mixed content

### ✅ Financial Domain Awareness
- Trained on real financial inquiry datasets
- Domain-specific entity extraction
- Confidence scoring for decision-making

### ✅ Production Ready
- Error handling and logging
- Graceful degradation
- Model versioning
- API documentation (Swagger/OpenAPI)

## Configuration

### Environment Variables (`.env`)
```
# HuggingFace Models
HF_TOKEN=your_huggingface_token_here
HF_REPO_ID=rohin30n/Armour

# ASR Configuration
ASR_MODEL_SIZE=large-v3
LANGUAGE_DETECT_MODEL=small

# API Settings
API_PORT=8000
API_HOST=0.0.0.0
```

## Deployment

### Docker
```bash
docker build -t integration-armour .
docker run -p 8000:8000 integration-armour
```

### Cloud Deployment
- **Render**: https://render.com (free tier available)
- **Railway**: https://railway.app (simple deployment)
- **Heroku**: https://herokuapp.com (traditional option)

## Technical Stack

- **Framework**: FastAPI + Uvicorn
- **ASR**: Faster-Whisper + AI4Bharat indicwav2vec
- **NLP**: Hugging Face Transformers
- **ML**: PyTorch, TorchAudio
- **Database**: SQLite (configurable)
- **Logging**: Python logging + structured logs

## Dependencies

### Core Requirements
- faster-whisper >= 0.10.0
- transformers >= 4.36.0
- torch >= 2.0.0
- librosa >= 0.10.0
- fastapi >= 0.104.0
- pydantic >= 2.5.0

### Installation
```bash
pip install -r requirements.txt
```

## Troubleshooting

### Issue: Models not downloading
**Solution**: Check HF_TOKEN and internet connection
```bash
python -c "from huggingface_hub import whoami; print(whoami())"
```

### Issue: ASR latency high
**Solution**: Use 'small' model instead of 'large-v3' for faster inference

### Issue: Language detection incorrect
**Solution**: System now uses script-based detection for Hindi/Urdu - ensure audio quality

## For Hackathon Judges

**Quick Start Command**:
```bash
git clone https://github.com/shivangis-25/Debris.AI.git
cd Debris.AI
pip install -r requirements.txt
python quickstart.py
