Chatbot vs. voicebot: A detailed comparison of conversational AI for customer support

By Trevor Jonas
November 17, 2025

Quick summary

Support teams choosing between chatbots and voicebots need clear guidance on which tool fits their needs. This article compares both technologies across features, use cases, and limitations. You'll learn how each works, where they add the most value, and how Replicant supports automation across voice and chat to improve speed, efficiency, and customer experience.

Torn between using a chatbot or a voicebot for customer support?

Customers expect fast responses no matter how they reach out. According to recent industry data, 40% of contact centers report increased demand for 24/7 availability. Teams can't meet these expectations by hiring alone, especially with agent turnover rates between 30% and 45% annually.

Conversational AI offers a practical solution. Chatbots handle text-based inquiries across web chat and messaging apps. Voicebots manage phone conversations with speech recognition and real-time responses. Both reduce workloads and improve service quality, but they serve different channels and use cases.

This article compares chatbots and voicebots across features, benefits, and best-fit scenarios. You'll see where each excels and how Replicant delivers advanced automation for both voice and chat.

What is a chatbot?

Chatbots are automated tools designed for text-based conversations. They use natural language processing to understand customer questions and deliver quick replies. Common tasks include answering frequently asked questions, collecting information, and guiding users through simple steps. Teams deploy chatbots on websites, mobile apps, and messaging platforms to handle routine inquiries without human handoff.

What is a voicebot?

Voicebots are AI systems that handle spoken conversations on phone and voice channels. They use speech recognition and natural language understanding to respond in real time. Core tasks include answering common questions, routing calls, and handling simple issues. AI voicebots work well for high-volume phone support where customers expect quick, hands-free help.

Best use cases for a chatbot

Handling FAQs

Chatbots excel at answering repetitive, straightforward questions on web chat or messaging apps. With a chatbot handling FAQs, customers get instant answers to common inquiries about hours, policies, or account basics without waiting for an agent.

Guiding users through simple steps

They walk customers through troubleshooting, onboarding flows, and form-style interactions. Step-by-step guidance helps users complete tasks independently while reducing the need for agent intervention.

Collecting customer information

Chatbots work well for intake forms, account details, and lead capture. They gather necessary information upfront so agents have context when handling more complex requests.

Managing order or account updates

They pull basic data like order status or appointment reminders. Customers check information quickly without tying up phone lines or waiting in chat queues.

Supporting after-hours conversations

Chatbots maintain coverage when human agents are unavailable. Customers get consistent service during nights, weekends, and holidays without requiring extra staffing.

Best use cases for a voicebot

Voicebots handle real-time phone conversations—answering questions, identifying intent, and resolving common requests without requiring a live agent.

Handling high-volume phone queries

Voicebots manage routine questions that flood phone lines, such as billing and payments, account checks, or basic troubleshooting. They reduce wait times and free agents for issues that require human judgment. In fact, Sunrun was able to resolve 50% of payment-related calls by deploying Replicant’s AI agents to handle conversations in English and Spanish.

Routing and triage

They identify caller intent, gather key details, and send customers to the right team or agent. Smart call routing reduces transfers and ensures faster resolution.

Verifying customer information

Voicebots handle authentication steps, identity checks, and account detail confirmation before handoffs. Secure verification happens quickly without manual effort from agents.

Managing time-sensitive requests

They work well for urgent calls like account and order management, cancellations, or appointment scheduling. Customers get immediate help without waiting on hold during critical moments.

Supporting after-hours or overflow calls

Voicebots help teams stay responsive during peak hours, holidays, and outside business hours. Consistent service continues when call volumes exceed available agent capacity. 

To that end, Engine deployed Replicant’s AI agents to handle hotel cancellations, which can happen at any time. Today, Replicant's AI Agents handle those calls from end to end, identifying eligible bookings, confirming policy compliance, and completing the cancellation instantly.

FAQ

What is the difference between a chatbot and a voicebot?

The main difference is the channel they operate on. Chatbots handle text-based conversations on web chat, messaging apps, and in-app experiences. Voicebots handle spoken conversations over the phone using speech recognition and real-time responses. Both use conversational AI, but they serve different customer behaviors and support needs.

When should a contact center use a chatbot vs a voicebot?

Chatbots work best for digital-first interactions like FAQs, order updates, and guided workflows on chat or messaging channels. Voicebots are ideal for call-heavy contact centers that need to handle high volumes of phone inquiries, routing, authentication, and time-sensitive requests. Many teams use both to support customers across channels.

Can chatbots and voicebots work together?

Yes. Chatbots and voicebots often work best as part of a unified support strategy. Customers may start in chat and switch to voice, or vice versa. When both systems share knowledge and context, teams deliver more consistent experiences and reduce repeat explanations across channels.

How does AI improve customer support across voice and chat?

AI improves customer support by automating routine interactions, reducing wait times, and surfacing insights that help teams improve performance. Platforms like Replicant analyze conversations across voice and chat, enabling better routing, coaching, and end-to-end resolution while allowing human agents to focus on complex issues.
