Jamie — Appointment Scheduling Voice Assistant Jamie is a voice AI I built for Wellness Partners, a multi-specialty health clinic, to handle appointment scheduling and patient coordination through natural, efficient conversations. Jamie schedules, confirms, reschedules, and cancels appointments while maintaining a friendly, professional tone—ideal for guiding patients of all ages. Built on OpenAI’s GPT-4o Mini Cluster and integrated with Vapi and Deepgram, Jamie delivers real-time speech recognition, transcription, and intelligent scheduling with precision and speed. With ~840 ms latency and a cost of ~$0.09 per minute, Jamie helps clinics automate front-desk tasks without losing the human touch. This project shows how voice AI can simplify patient communication and make scheduling faster and more human.
