Voice Is Evolving — And AI Is Leading the Shift
The days of robotic IVR menus and rigid phone trees are over. Customers expect natural conversations, instant answers, and intelligent automation that feels human. Businesses expect faster handling, reduced agent load, and scalable support that operates 24/7.
To deliver this new standard, you need real-time voice infrastructure + AI that understands and responds intelligently.
That’s exactly what happens when you combine Opentact’s telecom engine with GPT-powered voice AI.
Opentact handles the call. GPT handles the brains. And together, they create a fully automated, conversational voice experience that transforms how businesses interact with callers.
This is the future of voice — and you can build it today.
1️⃣ Why Combine Opentact and GPT?
Opentact gives you everything needed to process live calls:
SIP & WebRTC voice
ASR (speech recognition)
TTS (text-to-speech)
Real-time event streaming
Call routing & flows
Recording & analytics
GPT adds the intelligence layer:
Understands natural language
Responds conversationally
Adapts to context
Integrates with databases & APIs
Makes decisions dynamically
Together, they form a powerful voice automation stack that feels more like talking to a real human than interacting with a bot.
2️⃣ How the Opentact + GPT Voice Pipeline Works
Here’s how a single conversation unfolds when a caller interacts with a GPT-powered voice agent on Opentact:
Step 1: Caller Speaks → Opentact ASR Converts to Text
Opentact’s ASR engine listens and turns real-time speech into clean text.
Example: Caller says, “Can you check my balance?” ASR outputs: "check my balance"
Step 2: Text Sent to GPT
That text is passed to GPT through your backend or API integration.
GPT can:
Look up user data
Trigger workflows
Ask clarification questions
Understand open-ended intent
Step 3: GPT Generates a Natural Response
GPT returns an intelligent, human-like reply such as: “Sure, I can help with that. Please verify your 4-digit PIN.”
Step 4: Opentact TTS Converts Response to Audio
Opentact transforms GPT’s output into speech in milliseconds.
Step 5: Voice Played to Caller
The caller hears a smooth, natural voice response and continues the conversation.
Step 6: Continuous Loop
The flow repeats until the task is completed or the call is routed to a human agent.
This real-time system makes conversations feel fluid, smart, and fully interactive.
