Introduction: Voice AI Isn’t the Future - It’s What Your Callers Expect Now
People don’t want to wait on hold. They don’t want endless IVR menus. They don’t want “Press 1 for support, Press 2 for sales.”
They want answers, instantly, and in natural language.
By combining Opentact’s real-time voice engine with ChatGPT’s conversational intelligence, you can turn any inbound phone number into a smart, responsive, AI-powered voice assistant that talks, thinks, responds, and acts like a real human — 24/7, at scale.
This isn’t another IVR. This is live AI conversation, running directly on your inbound calls.
Let’s break down how it works — and why businesses are adopting it faster than ever.
1️⃣ Why Add ChatGPT to Your Inbound Calls?
Because it instantly upgrades your customer experience by delivering:
Natural conversations instead of rigid menus
Instant answers, no waiting
Consistent responses, no agent errors
24/7 availability
Automated task completion (appointments, lookups, tickets, etc.)
Lower operational costs
Higher call satisfaction
With Opentact + ChatGPT, your phone number becomes a smart entry point into your business.
2️⃣ The Opentact + ChatGPT Pipeline: How It Works
Here’s how a single inbound call becomes an intelligent AI-powered conversation:
Step 1: Caller speaks → Opentact converts voice to text (ASR)
The call is answered automatically, and Opentact’s ASR (Automatic Speech Recognition) instantly transcribes the caller’s voice.
Example spoken input: “Hey, I need to change my delivery address.”
ASR output: "I need to change my delivery address"
Step 2: Opentact sends transcription to ChatGPT
The text is passed to your ChatGPT API endpoint.
ChatGPT interprets the request, understands intent, and formulates a response — even handling multi-step reasoning.
Step 3: GPT’s response returns to Opentact
ChatGPT returns a text reply like:
“Sure, I can help you with that. Could you share the new address?”
Step 4: Opentact converts text back to speech (TTS)
Opentact reads the response aloud using natural-sounding Text-to-Speech.
Step 5: Conversation loop continues naturally
The AI engages the caller just like a trained human agent:
clarifying questions
sentiment-aware responses
task execution
context retention
escalation when necessary
You’ve just created an AI-powered inbound agent.
3️⃣ What Your AI Voice Agent Can Do
A. Solve Customer Support Requests
Your AI agent can handle common queries such as:
Order tracking
Password resets
Billing questions
Account updates
Refund status
Troubleshooting
No more long wait times — the AI handles it instantly.
B. Qualify Leads Before Sending to Sales
Instead of routing every caller to a human, your AI can:
Ask qualification questions
Gather required data
Score intent
Route hot leads to the right rep
Sales teams get better calls, not more calls.
C. Schedule Appointments Automatically
Your AI agent can interact with your calendar via API:
Book appointments
Reschedule calls
Confirm bookings
Send follow-up SMS
Perfect for clinics, salons, consultants, and service providers.
D. Provide Custom Account Information
With API integration, callers can ask:
“What’s my balance?”
“Is my payment received?”
“When does my subscription renew?”
ChatGPT handles the language. Opentact handles the voice. Your backend provides the data.
E. Route Calls When Human Help Is Needed
Not every call will be fully automated. Opentact supports:
Warm transfer to agents
Queue routing
Failover flows
Department-based forwarding
The AI hands off the conversation smoothly.
