The author shares experience building a voice agent for customer support, specifically for appointment scheduling. Despite the simple use case, the agent struggles with unexpected customer questions (e.g., doctor availability, costs, bringing children), often revealing its non-human nature. The author notes that training a voice agent is like training a junior employee: it requires supervision, it makes mistakes, and it improves over time, yet people often expect AI to be perfect out of the box.
