What Is AI Calling Agent?
An AI calling agent is an autonomous software system powered by streaming speech recognition (STT), large language models (LLMs), and neural voice synthesis (TTS) that conducts two-way natural voice conversations over standard phone lines and WebRTC. Unlike rigid IVRs or robotic robocallers, AI calling agents understand human intent, adapt to interruptions (barge-in), ask intelligent follow-up questions, and execute real-time actions like booking appointments and updating CRM fields.
