如何构建一个能够接听餐厅电话的 AI 语音助手

Last year, the author began building an AI voice agent designed to answer phone calls for restaurants. The motivation stemmed from the observation that restaurants miss a significant number of calls during busy hours, leading to direct revenue loss. Before writing any code, the author spoke with around 30 restaurant owners and found a consistent pattern: during peak hours (lunch rush, dinner rush, weekends), staff are too occupied serving in-house customers to answer the phone. Calls often go to voicemail, and callers rarely leave messages, opting instead to call the next restaurant. This research helped clarify the project's direction and requirements, ultimately leading to an efficient solution aimed at reducing missed calls and potential revenue loss for restaurants.
