In today’s hyper-connected world, voice automation is no longer optional—it’s your competitive edge. A custom AI voice agent can handle customer queries, qualify leads, and even schedule appointments without missing a beat.

In this post, we’ll explore what AI voice agents are, how they work, and how Eplanet Soft can help your business harness their full power.

🤖 What Is a Custom AI Voice Agent?

A custom AI voice agent is a smart, human-sounding assistant that speaks to your customers via phone in real time. Built using Natural Language Processing (NLP) and Text-to-Speech (TTS) technologies, these agents can converse, understand intent, and take action—just like a human.

Unlike outdated IVRs, these bots don’t just say “Press 1.” They ask questions, respond naturally, and even handle objections.

🔧 How AI Voice Agents Work

Here’s what happens behind the scenes:

  • Speech-to-Text (STT): The agent listens and transcribes the caller’s voice.

  • NLP Processing: It understands what the customer wants.

  • Conversational Engine: It uses GPT-based models to craft a response.

  • TTS Output: The response is spoken back in a clear, human-like voice.

  • CRM/Data Integration: All interactions are logged and synced with your backend.

Eplanet Soft’s AI voice agents are powered by GPT-4, Twilio Voice API, and real-time speech synthesis for seamless performance.
