Top conversational AI examples for smarter interactions

Conversational AI examples: real-world uses across industries

Quick answer

Conversational AI is technology that understands human language and responds in a back-and-forth dialogue across text and voice. You already use it every day: voice assistants like Siri and Alexa, the support chatbot on a retail site, and the automated agent that answers a customer service line. Examples span four broad types: AI chatbots, voice assistants, AI voice agents, and agentic AI, across both consumer and business settings.

What is conversational AI?

Conversational AI is software that interprets what a person says or types and responds in natural, human-like language. Unlike a scripted menu, it handles open-ended input and keeps the thread of a conversation going across multiple turns.

A few components work together to make this possible. Natural language understanding (NLU) figures out intent, dialogue management decides what to do next, and natural language generation (NLG) produces the reply. Voice systems add two more layers: speech-to-text (STT) converts spoken words into text, and text-to-speech (TTS) turns the response back into audio.

The technology builds on natural language processing and machine learning, and modern systems increasingly use large language models (LLMs) to interpret and generate language. For a deeper breakdown of how these systems differ from general-purpose generative models, see our guide on conversational AI versus generative AI. The rest of this page focuses on the examples.

The main types of conversational AI

Most conversational AI falls into one of four categories. They overlap, and a single product can combine several, but the distinctions clarify what each is good at.

AI chatbots

A chatbot is text-based conversational AI that lives on a website or in an app. It reads what you type and replies in text, and modern versions increasingly run on an LLM rather than rigid keyword rules.

Bank of America's Erica is a well-known example. Launched in 2018, the virtual financial assistant has surpassed 3 billion client interactions and now averages more than 58 million interactions per month. Other common cases include retail support bots that track orders and banking assistants that answer balance questions. Erica has grown from answering a couple hundred question types at launch to more than 700 intents today.

Best for: scalable text support, FAQs, and self-service inside an app or website.

Voice assistants

Voice assistants respond to spoken language. They run speech-to-text on what you say, work out the intent, then use text-to-speech to answer out loud. Apple's Siri, Amazon's Alexa, and Google Assistant are the household names, and ChatGPT's voice mode is a newer entrant built on a generative model. These third-party assistants are becoming a default front door to services: Gartner expects 70% of customer service journeys to begin and end in conversational assistants on mobile devices by 2028.

The scale here is enormous. Amazon has reported more than 600 million Alexa devices sold worldwide, spanning its own Echo line and third-party products.

Best for: hands-free consumer tasks, quick information lookups, and smart-home control.

AI voice agents

An AI voice agent handles real-time business phone conversations. Under the hood it runs a live loop, speech-to-text, then an LLM, then text-to-speech, over a telephony connection, fast enough to feel like a natural call. The difference from a consumer voice assistant is the job: these agents answer support lines, book appointments, and route callers inside a company's phone system.

Best for: inbound and outbound phone interactions at scale, where a caller expects a real conversation rather than a menu.

Agentic AI

Agentic AI goes a step further than answering questions. The model plans a task, calls tools or APIs, and takes action to finish it. A voice agent that looks up an order, confirms the details, and processes a return is acting agentically rather than just replying.

This is the fastest-moving category. Gartner predicts that agentic AI will autonomously resolve 80% of common customer service issues without human intervention by 2029, a shift the firm links to a roughly 30% reduction in operational costs.

Best for: end-to-end task completion that spans several steps and systems.

Types of conversational AI at a glance

Everyday examples of conversational AI

You interact with conversational AI more often than you might notice. The most recognizable cases include:

Phone assistants: Siri and Google Assistant answer questions, set reminders, and send messages directly from your phone.

Home assistants: Alexa on an Echo speaker and Google Assistant on a Google Home device control lights, play music, and run timers by voice.

Customer support chatbots: The chat window that opens on a retail or banking site answers common questions and hands off to a human when needed.

IVR and call-center agents: When you call a company and a natural-sounding system asks what you need, then routes or resolves the call, that is conversational AI replacing the old press-one menu.

In-app help: Software products embed assistants that answer how-to questions and walk you through features without leaving the app.

Conversational AI examples by industry

Different sectors apply the same core technology to very different problems. Here is one concrete scenario for each.

Customer service and telecom: Klarna's OpenAI-powered assistant handles two-thirds of the company's customer service chats. In its first month it ran 2.3 million conversations, which Klarna described as the equivalent work of 700 full-time agents, resolving issues in under two minutes versus 11 minutes for a human. The story has a useful second chapter: by 2025 Klarna reopened hiring for human support roles after deciding it had leaned too far into automation, a reminder that AI handles the high-volume tier while people handle the rest.

Healthcare: Universal Health Services has deployed Hippocratic AI's generative voice agents to make post-discharge follow-up calls to patients, starting at its Summerlin Hospital in Las Vegas and Texoma Medical Center in Texas. Separately, University Hospitals in Ohio is rolling out the same vendor's agents for non-diagnostic tasks like appointment support and preventative screening outreach. Both keep clinical judgment with humans and use AI for routine outreach.

Financial services: Bank of America's Erica answers balance questions, flags transactions, and helps with payments inside the mobile app. The bank reports that 98% of clients find the information they need, usually in under a minute, across billions of interactions since 2018.

E-commerce: Sephora was one of the first retailers to put conversational AI on a messaging platform. Its Reservation Assistant lets customers book in-store makeover appointments through chat, and the company reported an 11% higher booking conversion rate through the bot than through other channels. A companion Color Match bot recommends products from a photo.

Travel and logistics: Gatwick Airport runs a chatbot named Gail that answers flight, baggage, and facility questions for passengers. At launch it understood and answered about 80% of the questions it received, with the airport targeting 95% as the system learned. Gail is still live on the airport's site today for real-time flight information.

Conversational AI examples by business function

Cut across industries and the same handful of jobs show up everywhere.

Booking and scheduling: Sephora's Reservation Assistant books in-store makeover appointments through a chat conversation, asking for the service and location and returning open times. The retailer credited it with an 11% lift in booking conversion over other channels.

Answering FAQs and resolving issues: Gatwick's Gail fields passenger questions about flights, baggage, and airport facilities, answering around 80% of incoming questions on its own and escalating the rest. This is the highest-volume, lowest-risk function and usually the first one teams automate.

Routing callers: Traditional IVR menus are giving way to natural-language agents that ask what you need and connect you to the right place. This shift is large enough that Gartner expects 30% of Fortune 500 companies to offer service through a single AI-enabled channel by 2028, collapsing the old menu tree into one conversation.
Outbound outreach: Klarna's assistant does more than resolve tickets; it is embedded in the shopping flow, answering product and payment questions at the moment of purchase, which the company tied to a $40 million projected profit improvement. Conversational AI on the sales side qualifies interest, answers questions, and books demos.

Data collection: Data collection. Voice and chat agents gather structured information during a conversation and write it straight into a system of record. Hippocratic AI's post-call summaries, which log topics covered and flag concerns back to the medical record, are one example of capture-and-document in action.

Benefits of conversational AI

Businesses adopt conversational AI for a few consistent reasons. It runs 24/7, so customers get answers outside business hours. It scales routine interactions without adding headcount, which is why Gartner has projected that conversational AI deployments will reduce contact center agent labor costs by $80 billion in 2026. It resolves common requests faster, answers consistently every time, and supports multiple languages from one system. Adoption is accelerating: Gartner predicts that by 2028, at least 70% of customers will use a conversational AI interface to start their customer service journey.

The honest limit: complex, sensitive, or emotional cases still need a human. The strongest deployments use AI for high-volume routine work and route everything else to a person, with an easy path to escalate.

Building your own conversational AI

For voice especially, a real conversational AI agent needs four things working together in real time: speech-to-text, an LLM, text-to-speech, and the telephony that connects the call. The latency between those steps decides whether the conversation feels natural or stilted.

Telnyx runs that full stack on one network, with inference colocated near its global points of presence and connected directly to the voice API and PSTN. You can build a voice AI agent without stitching together separate vendors, or start without code using the no-code voice assistant docs.

Frequently asked questions

What is an example of conversational AI?

A voice assistant like Siri or Alexa is a clear example, as is the support chatbot on a retail or banking website. Bank of America's Erica, which has handled billions of client interactions, is one of the most widely used. All of them understand language and reply in a natural dialogue.

What are the main types of conversational AI?

There are four. AI chatbots handle text on websites and apps. Voice assistants respond to speech. AI voice agents run real-time business phone calls. Agentic AI takes actions and uses tools to complete multi-step tasks rather than only answering questions.

Is ChatGPT conversational AI?

Yes. ChatGPT is a generative AI model wrapped in a conversational interface, including a voice mode. It understands open-ended input and responds in dialogue, which makes it conversational AI, though it is built for general tasks rather than a single business workflow.

Is Siri an example of conversational AI?

Yes. Siri is a voice assistant. It converts your speech to text, interprets what you want, and answers out loud using text-to-speech. That speech-in, speech-out dialogue is exactly what defines conversational AI in the voice category.

What is the difference between a chatbot and conversational AI?

A chatbot is one form of conversational AI, specifically text-based dialogue. Conversational AI is the broader category that also includes voice assistants, AI voice agents, and agentic AI. Every chatbot is conversational AI, but not all conversational AI is a chatbot.

What is the best conversational AI for real-time voice?

The best fit depends on latency, telephony reach, and cost. Real-time voice needs speech-to-text, an LLM, and text-to-speech running in a tight loop over a phone connection, so platforms that keep those components on one low-latency network tend to perform best for multi-turn voice scenarios.
