📞 Voice Call - Make Voice Calls with Your AI

Turn your web chatbot into an interactive voice assistant

Voice Call lets your visitors talk directly to your AI agent via the web chatbot, just like making a phone call. This revolutionary feature provides a more natural and accessible user experience.

🎯 Overview

Voice Call transforms your chatbot experience by allowing users to:

• Speak naturally instead of typing
• Receive voice responses from the AI
• View real-time transcription
• Switch between text and voice at any time

Availability

Voice Call is available on all web integrations: iframe widget, WordPress, PrestaShop, Joomla, and any site using our web integration.

🚀 How to Enable Voice Call

Step 1: Access Agent Configuration

1. Log in to your AI SmartTalk back-office
2. Go to Agents in the main menu
3. Select the agent you want to configure

Step 2: Enable the Feature

1. Click on the Channels tab
2. Select Web
3. Enable the "Enable Voice Call" option
4. Save your changes

Step 3: Set Voice Options

Option	Description

🔄 How It Works

Conversation States

During a voice call, the interface displays different states:

State	Description
📄 Retrieving documents	AI searches your knowledge base
🤔 Thinking...	AI analyzes the request and prepares a response
🔊 Speaking	AI is responding with voice
🎙️ Listening	AI is listening to the user

Conversation Flow

User speaks → STT (transcription) → AI analyzes → Generates response → TTS (speech synthesis)

1. Speech-to-Text (STT): The user's voice is transcribed to text
2. AI Processing: The agent analyzes the request with access to your knowledge base
3. Text-to-Speech (TTS): The response is converted to natural voice
