AI Voice Agents

What are AI voice agents?

AI voice agents listen and respond during a live conversation. A business can place one on a phone line or website to answer questions, collect details and guide a caller through a task. Unlike a text-to-speech generator, an agent follows the conversation, can ask clarifying questions and may use approved tools to take action.

Common uses

Teams use voice agents for reception, support, appointment requests, lead qualification and guided troubleshooting. Some products also accept text, camera or shared-screen input. Those extra channels are useful when the agent needs to discuss something visible, but they are not required for every voice agent.

How to compare tools

Test interruption handling, language support, phone and web deployment, knowledge grounding, integrations and transfer to a human. Check the pricing unit and any concurrency limits. If conversations contain personal information, review recordings, retention, regional processing and consent before deployment. Run a realistic call and inspect its transcript and outcome.
