Add Conversational AI into IoT Devices for Smarter Real-Time Interaction

Artificial intelligence is no longer limited to cloud platforms or smartphones—it’s now transforming the way we interact with everyday technology. Smart devices are no longer satisfied with simply following commands—they’re learning to talk back. As developers add conversational AI into IoT devices, products like smart speakers that recognize emotions and AI toys that remember conversations are redefining what intelligence means, moving far beyond simple automation toward truly human-like interaction.

Today, the convergence of AI and IoT (Internet of Things) is ushering in a new era of human-device relationships. Devices are no longer passive tools awaiting precise commands; they are becoming responsive partners capable of understanding context, emotions, and intent.

However, achieving seamless communication between humans and machines requires overcoming a unique set of challenge—low latency, multimodal interaction, and emotional intelligence. Traditional IoT systems often struggle with fragmented cloud dependencies, high latency, and limited conversational flow.

To address these challenges, ZEGOCLOUD’s AI solution for IoT devices integrates advanced real-time communication (RTC) technology with AI Agents, enabling natural, low-latency, and emotionally aware interactions across various smart devices — from toys and wearables to home companions and translation hardware.

From Command-Based to Conversational: The Evolution of Smart Devices

In the early stage of IoT, devices were purely functional — users issued commands, and machines responded. Whether it was a voice-controlled light bulb or a basic home assistant, interaction relied on precise, single-round instructions.

But as user expectations grew, this model began to show its limits. Today’s users, especially younger generations, expect continuous, context-rich, and emotionally intelligent interactions. The focus has shifted from utility to companionship.

Modern AI hardware delivers value through natural, scenario-based dialogue. Instead of users saying, “Turn on the light,” they can now say, “It’s getting dark in here,” and the device interprets and acts accordingly. This marks the transition from “accurate instruction” to “fuzzy understanding.”

ZEGOCLOUD’s AI architecture captures this transition by enabling low-latency, multimodal communication that combines voice, video, and behavioral cues. The result is a system capable of intuitive understanding — devices that feel more like companions than tools.

Market Demand to Add Conversational AI into IoT Devices

The value of next-gen AI hardware is its ability to understand context and intent, not just a predefined set of words. The shift toward humanized AI is reshaping multiple IoT verticals:

Smart Toys and Companions

AI-powered toys like BubblePal or Tom Cat LOVOT cater to children, parents, and even seniors.

For kids: the toys tell stories, answer questions, and support learning.
For adults: they provide emotional comfort through expressive behavior and empathetic dialogue.
For seniors: they act as companions offering both interaction and reminders for daily health routines.

Through emotion recognition, voice detection, and memory-based dialogue, ZEGOCLOUD-powered smart toys can build real emotional bonds — something traditional hardware could never achieve.

Wearables and Smart Assistants

Devices like AI glasses and earbuds are transforming workplace and lifestyle experiences. They support real-time translation, speech-to-text transcription, meeting summaries, and AI-driven assistance—all processed with low latency.

Visual features such as object recognition, AI navigation, and photo-based Q&A enhance both productivity and daily convenience.In these applications, ZEGOCLOUD ensures instant voice response, continuous conversation, and multilingual capabilities, creating frictionless user experiences.

The Challenges Behind AIoT Innovation

Despite the immense potential, building intelligent IoT products faces several critical challenges:

1. The Multi-Round Dialogue Dilemma

The ubiquitous “push-to-talk” mode is a compromise. It improves accuracy but shatters the natural flow of conversation, frustrating users who forget to press the button or find the process cumbersome.

2. Recognition Accuracy in Complex Environments

Real-world environments are noisy. Background TV, children playing, traffic sounds, and echoing rooms cripple generic Automatic Speech Recognition (ASR) models, especially when dealing with children’s voices or dialects. Accuracy can plummet to around 80%, making the device feel broken.

3. The Latency vs. Cost Challenge

Achieving real-time interaction with a cloud-based stack (ASR + LLM + TTS) is difficult. Network instability causes delays, while self-hosted solutions are expensive, and commercial cloud services can be complex and costly to integrate and operate at scale.

ZEGOCLOUD’s AI Solution for IoT Devices

ZEGOCLOUD’s AI Agent solution is a full-stack framework designed to empower IoT manufacturers with real-time, natural communication capabilities.

Key Components

ASR (Automatic Speech Recognition): Detects and converts speech instantly, even across noisy conditions.
TTS (Text-to-Speech): Generates natural-sounding voice responses with customizable tones.
LLM Integration: Enables intelligent, contextual understanding using both domestic and international models such as OpenAI, Doubao, and Tongyi Qianwen.
RTC Layer: Built on ZEGOCLOUD’s globally distributed MSDN network (500+ nodes) and proprietary AVERTP protocol, guaranteeing end-to-end low latency and stable connectivity.

Multi-Mode AI Interaction: Human-Like Conversational Experiences

ZEGOCLOUD’s AI framework supports multiple forms of voice interaction to accommodate varied use cases:

Continuous Multi-Round Dialogue

Once activated, the device maintains memory of past exchanges, enabling contextually rich follow-ups. For example, when a child asks, “Where’s the red dinosaur I talked about yesterday?” The device recalls previous conversation history.

Intercom-Style Quick Chat

This “push-to-talk” variation remains valuable for short commands or temporary device control. It mimics traditional walkie-talkie operation for situations like smart home adjustments or rapid task delegation.

Multi-User Voice Recognition

By combining voiceprint recognition and round-level VAD, ZEGOCLOUD allows devices to distinguish between users. This is crucial in shared environments like families or classrooms. Each user’s interaction history can be remembered, providing a personalized experience.

Multi-Agent AI Conversation

Users can simultaneously interact with multiple AI personas — for instance, discussing philosophy with “Confucius” and “Socrates” at once. This multi-agent feature opens up new educational and entertainment experiences.

Rich AI Interactions And External Synergy

Building upon its core conversational abilities, the AI unlocks a suite of rich, dynamic interactions. It can bring stories to life with immersive narration, host interactive singing sessions, and learn user preferences through an integrated memory. By leveraging the MCP protocol, it extends beyond conversation to control smart homes and fetch online information, evolving into a central hub for the user’s digital life.

The Technical Breakthroughs: Achieving Ultra-Low Latency And High Accuracy

ZEGOCLOUD’s core technical strengths are built around speed, adaptability, and reliability — key pillars when you add conversational AI into IoT devices.

End-to-End Voice Low Latency

By combining streaming ASR, flow-based TTS, and incremental LLM output, the system reduces communication delay to under one second, ensuring real-time responsiveness.

Superior Complex Scenario Recognition

Maintains over 95% accuracy in challenging conditions like noise, interruptions, and background music.

Broad Hardware Compatibility

Deeply optimized for popular AIoT chips (ESP32, BK7258) and supports all major ASR (OpenAI, Tencent, Azure) and TTS (Volcano, MiniMax, CosyVoice) providers.

Global, Stable And Cost-Effective Service

A global network of RTC nodes ensures users connect to the nearest server for the fastest possible path. Futhurmore, ZEGOCLOUD’s solution smartly pauses ASR tasks during silence, reuses TTS sessions, and optimizes LLM concurrency to minimize overhead — reducing operational cost by over 50%.
