Develop Retell AI Voice Interface for Approval

Create a real-time voice interface using Retell AI that allows a human developer to review the proposed refactorings and give verbal approval or request modifications. The `ApprovalAgent` in your LangGraph should transition to a 'waiting_for_voice_input' state, and upon receiving verbal confirmation via Retell AI, update the state to proceed with code application. ```python
# Assume Retell AI webhook endpoint /retell-webhook is set up
from flask import Flask, request, jsonify
import threading
import queue app = Flask(__name__)
voice_input_queue = queue.Queue() @app.route('/retell-webhook', methods=['POST'])
def retell_webhook(): data = request.json # Process Retell AI events, push confirmation to queue if data.get('event') == 'call_ended' and 'yes' in data.get('transcript', '').lower(): voice_input_queue.put('approved') return jsonify({'status': 'ok'}) def start_flask_server(): app.run(port=5000, debug=False) def approval_node(state: AgentState): print("---AWAITING VOICE APPROVAL---") # Logic to poll voice_input_queue for approval # Update state['next_action'] based on approval return state # Start Flask server in a separate thread
# threading.Thread(target=start_flask_server, daemon=True).start()
```
