Voice AI Agent
An AI system that conducts natural, full-duplex voice conversations with humans in real time - receiving spoken input, processing it through a language model, and responding with synthesized speech in under 500 milliseconds. Distinguished from older interactive voice response (IVR) systems, which present pre-recorded menus and require button presses or simple spoken commands, voice AI agents support free-form conversation, contextual follow-up, and complex multi-turn dialogue. Loman.ai's voice AI agent for restaurants illustrates the commercial use case: it answers the phone as if it were a human employee, knows the full menu and real-time stock status via POS integration, takes orders that print directly in the kitchen, and builds a diner profile from every call. About 40% of callers cannot tell they are speaking to AI - a benchmark that prior-generation voice systems never approached.
