+# 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

+- 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

+- **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)

+
+## 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
+
