What is AI Voice Testing Platform?

AI Voice Testing Platform is a Flask-based SaaS application that allows you to test business phone flows using the same AI caller in two different modes:
  • Web Chat Mode: Roleplay as your business while an AI agent behaves like a customer or caller, helping you test conversation flows interactively
  • Outbound Phone Call Mode: Trigger real phone calls to any phone number using ElevenLabs and Twilio, with the same caller context and scenario
This dual-mode approach lets you rapidly iterate on phone flow scripts, test IVR systems, and validate customer service workflows before deploying them to production.

​
Key Features

Dual Testing Modes

Test phone flows through web chat or real outbound calls with the same AI caller persona

AI-Powered Conversations

Uses OpenAI GPT-4o-mini for intelligent chat responses and ElevenLabs for natural voice synthesis

Scenario-Based Testing

Define custom caller goals like “check appointment availability” or “complete a booking”

Session Management

Maintains conversation context across multiple turns with Flask sessions

​
How It Works

1

Define Your Business Context

Enter a description of your business and phone flow. This context helps the AI understand how to interact authentically.Example: “A dental office with an automated scheduling system that handles appointment bookings, cancellations, and insurance verification.”
2

Set a Caller Scenario

Specify what task the AI caller should accomplish during the conversation.Example: “check appointment availability for a teeth cleaning next week”
3

Start Testing

Choose your testing mode:
  • Web Chat: Interact directly with the AI caller through a browser interface
  • Phone Call: Trigger an outbound call to a real phone number to test your actual phone system
4

Analyze Results

Review how the AI caller navigates your phone flow, identifies issues, and validates that customers can complete their tasks successfully.

​
Technical Architecture

The platform is built with:
  • Backend: Flask 3.0.0 web framework (Python)
  • AI Chat: OpenAI GPT-4o-mini for conversational intelligence
  • Voice Synthesis: ElevenLabs TTS API with eleven_turbo_v2_5 model
  • Phone Integration: ElevenLabs Conversational AI + Twilio for outbound calling
  • Session Management: Flask sessions with encrypted cookies
The AI caller is designed to behave like a real customer: it asks one thing at a time, speaks naturally, and tries to complete tasks without escalating to a human unless necessary.

​
Use Cases

​
IVR System Testing

Validate that your interactive voice response system correctly routes callers and handles common scenarios.

​
Customer Service Flow Validation

Ensure appointment booking, order tracking, and support workflows work smoothly from a customer’s perspective.

​
Script Iteration

Quickly test modifications to phone scripts without needing real customers or manual testing.

​
Training Data Generation

Capture realistic conversation flows that can be used to train customer service representatives.

​
What You’ll Need

To run the AI Voice Testing Platform, you’ll need:
  • Python 3.8 or higher
  • API keys for:
    • OpenAI (for chat-based conversations)
    • ElevenLabs (for voice synthesis and phone calls)
  • For phone calls:
    • ElevenLabs Conversational AI agent with prompt overrides enabled
    • Twilio-connected phone number in ElevenLabs
Outbound phone calls will use your ElevenLabs and Twilio credits. Test with web chat first to validate your scenarios before making real calls.
