ConvoAI – Voice-Based AI Assistant

Voice agent
Project Overview

ConvoAI is a voice-driven AI assistant that enables users to communicate with AI simply by making a phone call. It delivers natural, real-time, human-like conversations without apps or typing. 

The system is powered by OpenAI’s language models, integrated with Twilio’s Programmable Voice API, and supported by a Python (Flask) backend with WebSocket-based audio streaming. This ensures low latency, reliable VoIP call handling, and customizable conversational flows for use cases like customer support, appointment reminders, booking systems, and intelligent IVRs.

The Challenge

Companies that still depend on the old systems for their telephone operations faced certain issues:

  • Rigid IVR menus that forced callers through fixed keypad options.

  • Heavy workloads on humans who always took care of repetitive calls.

  • No accessibility for users who cannot look at screens or apps.

  • Limited room for personalizing responses according to the user’s intent.

Such constraints advocated for a flexible, conversational AI-powered voice solution.

Our Approach

So here, we have developed ConvoAI, a fully automated, real-time conversational system:

  • Implemented solutions using OpenAI LLMs and Realtime APIs for real-time, intelligent AI interactions.

  • Used Twilio Voice for telecom-grade call routing and VoIP handling.

  • It intelligently detects interruptions during conversations and tracks events in real time for smooth, context-aware interactions.

  • Built low-latency audio streaming with WebSockets for instant responses.

  • Designed a scalable Python/Flask backend capable of handling concurrent calls.

  • Added industry-specific custom workflows for bookings, support, FAQs, and reminders.

  • Implemented intelligent fallbacks, sentiment understanding, and smooth conversational recovery.
