AI voice agents combine speech recognition (ASR), large language model reasoning, and text-to-speech (TTS) to produce natural telephone conversations. They integrate with telephony platforms like Twilio, Vapi, or RingCentral to answer real phone numbers, and with CRMs and helpdesks to act on the conversations they have.
Common AI voice agent use cases include 24/7 customer support answering, outbound sales qualification, appointment scheduling, insurance claim intake, and after-hours call coverage. They typically identify themselves as AI (a growing regulatory expectation) and route to human agents on escalation signals.
Enterprise-grade AI voice agents are governed by a policy layer, logged in audit-grade detail, and integrated so they update the same systems human agents use — no parallel stack.
