Introduction: The Rise of Voice Automation
Voice automation is no longer a futuristic idea — it’s a practical, powerful tool that businesses of all sizes are embracing to enhance customer experience, reduce operational overhead, and scale support without scaling team size.
From answering FAQs to routing calls, confirming appointments, taking orders, and even handling complex workflows, intelligent voice bots are becoming the new frontline of communication.
And with Opentact, creating your own AI-powered voice bot is not only possible — it’s fast, flexible, and incredibly efficient.
Opentact combines SIP, WebRTC, ASR (Automatic Speech Recognition), TTS (Text-to-Speech), and API automation into a single platform, giving startups and enterprises everything they need to build and deploy intelligent voice bots at scale.
1️⃣ Why Build a Voice Bot with Opentact?
Opentact isn’t a basic IVR system — it’s a full-stack communication engine designed for real-time automation.
By building your voice bot on Opentact, you unlock:
Real-time speech-to-text understanding
Natural-sounding text-to-speech responses
Instant call routing and API-triggered actions
AI-ready infrastructure (ChatGPT integration supported)
Carrier-grade reliability with global scalability
Secure, encrypted voice flows
A no-hardware, cloud-native setup
This means your voice bot won’t sound robotic or slow — it will behave like an intelligent assistant capable of understanding, responding, and learning.
2️⃣ Understand the Core Components of an Opentact Voice Bot
To build a voice bot, you need to combine several communication features seamlessly. Opentact brings them all under one roof:
ASR (Automatic Speech Recognition): Converts spoken words into text so your bot can understand caller intent.
TTS (Text-to-Speech): Turns your bot’s responses into natural audio.
APIs: Allow your bot to interact with databases, CRMs, AI models, and business systems.
Call Flow Designer: Lets you build complex workflows visually.
Real-Time Event Control: Handle call events through WebSockets for instant bot responses.
With Opentact, these components work together automatically.
3️⃣ Step-by-Step: Building Your Voice Bot on Opentact
Step 1: Set Up Your Call Flow
Start by creating a new inbound call flow in the Opentact dashboard. This defines what happens when someone calls your number.
You can:
Play welcome prompts
Trigger ASR for user input
Route calls dynamically
Capture caller intent
Send responses through TTS
The drag-and-drop builder makes this visual and intuitive.
Step 2: Integrate ASR for User Interaction
Using Opentact’s built-in ASR, you can ask open-ended questions like:
“How can I assist you today?”
“Please describe your issue.”
“What product are you calling about?”
ASR instantly transcribes spoken replies and passes them into your logic engine or external API.
Step 3: Use APIs for Smart Decision-Making
Your voice bot becomes intelligent when it interacts with your systems.
For example:
“Track my order” → Bot fetches order status API
“I want to update my billing info” → Bot triggers CRM workflow
“Schedule a call” → Bot connects to your calendar API
Opentact supports REST & WebSocket integrations, enabling real-time AI-driven conversations.
Step 4: Add TTS to Respond Naturally
Your bot’s voice should feel confident, warm, and clear.
Opentact’s TTS engine converts any text into spoken audio. Combine this with your API logic to create dynamic responses, such as:
“Your order is arriving tomorrow.”
“Your account balance is $420.”
“I’ve scheduled your appointment for 3 PM.”
No manual recording needed — the bot speaks instantly.
Step 5: Add Failover Paths and Human Escalation
Even the smartest voice bot should offer human backup.
Configure your bot to:
Transfer to an agent when the user asks
Escalate when intent is unclear
Route to departments based on keywords
With Opentact’s routing engine, escalation is seamless.
