When Voice Becomes Intelligent, Your Business Becomes Unstoppable
AI voice assistants are no longer futuristic toys — they’re operational powerhouses. From answering support calls to booking appointments, qualifying leads, delivering account details, and even guiding customers through complex menus, AI-powered voice automation is quickly becoming the backbone of modern communication.
But building an AI voice assistant from scratch is challenging. You need real-time call handling, speech recognition, natural-sounding audio, APIs, call routing, security, and the ability to integrate with your business systems.
That’s where Opentact steps in.
Opentact gives you a full-stack, cloud-native communication engine with ASR, TTS, VoIP, routing, APIs, recordings, and AI integration. Everything you need to build an AI Voice Assistant — without building your own telecom infrastructure.
1️⃣ Why Build Your Voice Assistant on Opentact?
Because Opentact gives developers everything in one place:
Carrier-grade SIP & WebRTC voice
Automatic Speech Recognition (ASR)
Text-to-Speech (TTS)
ChatGPT-ready AI integration
Real-time event handling (WebSocket)
Drag-and-drop voice flows
API-driven automation
Instead of stitching together multiple tools, Opentact gives you a unified platform to build, test, deploy, and scale voice bots seamlessly.
2️⃣ Core Features That Matter for AI Voice Assistants
Automatic Speech Recognition (ASR)
Your voice assistant needs to understand callers. Opentact’s ASR engine converts speech into clean text instantly, enabling natural, open-ended conversation.
Text-to-Speech (TTS)
Your assistant must respond smoothly and professionally. With Opentact’s TTS, you can generate natural-sounding voice responses on the fly — no recordings required.
Real-Time Event Control
AI-powered voice needs split-second responsiveness. Opentact streams call events in real time, allowing your bot to respond instantly.
API Integration
AI assistants must connect to real business data:
CRM
Ticketing
Order system
Appointment calendars
Payment gateways
Support databases
Opentact seamlessly integrates with all of them through REST and WebSocket APIs.
3️⃣ Step-by-Step: Building an AI Voice Assistant on Opentact
Step 1: Set Up Your Inbound Call Flow
Create a new call flow in Opentact’s visual builder. Add steps such as:
Welcome prompt
Ask user intent
Activate ASR
Pass transcription to your AI logic
Respond via TTS
The flow can be as simple or complex as you need.
Step 2: Connect Your AI Logic (ChatGPT or Custom Model)
Your ASR output is sent to your backend or an AI engine like ChatGPT.
This allows your assistant to:
Understand natural language
Make decisions based on context
Trigger APIs
Provide personalized answers
Example AI tasks:
“Where is my order?” → Fetch order data
“Reschedule my appointment.” → Update calendar
“I want to upgrade my plan.” → CRM workflow
Opentact doesn’t limit your creativity.
Step 3: Generate the Bot’s Voice Response
Once AI generates a reply, Opentact’s TTS transforms it into spoken audio instantly.
You can customize tone, voice style, and language to match your brand.
Step 4: Add Intelligent Routing & Escalation
Your AI assistant can automatically route callers based on:
Intent
Keywords
Account status
Time of day
Agent availability
If a caller wants a human, Opentact can:
Transfer to a SIP user
Route to a queue
Send to a fallback IVR
Trigger a callback task
This ensures a frictionless customer experience.
Step 5: Record, Analyze, and Improve
Opentact automatically provides:
Call recordings
Call transcripts
Interaction logs
Analytics on call duration, sentiment, and outcomes
This helps refine your AI logic over time and improve accuracy.
