Voice AI
Also called: conversational voice AI
Voice AI is artificial intelligence applied to spoken language: recognizing what a person says, understanding intent, and responding with a natural synthetic voice — in real time, over a phone call or device.
Voice AI is the harder sibling of text-based conversational AI: it has to work sub-second, handle interruptions and accents, and stay coherent over a live call. That's why a purpose-built voice stack matters more than bolting speech onto a chatbot.
In business, voice AI shows up as AI voice agents that answer and place phone calls end to end.
