AgoraCare - Voice AI Healthcare Companion for Rural India

Voice AI Hackathon 2026 · AI Mobile Coders × Agora · Submission

A real-time Hindi/English Voice AI healthcare companion for rural India. Patients tap one button, speak in Hindi, and talk to an AI doctor — get medication reminders, log vitals by voice, and get instantly connected to a live human nurse over an Agora audio bridge in emergencies. No typing. No English required. Built for ₹5,000 Android phones.

The Problem

• 1 doctor per 1,456 people in rural India (WHO standard: 1 per 1,000)
• Elderly patients forget medications — non-adherence is a major cause of preventable harm
• Emergency response is slow — patients don't know when or how to escalate
• Language barrier — most health apps are English-only and text-first

AgoraCare solves this with voice. A 68-year-old farmer who can't read English can tap one button and speak.

Why Agora Conversational AI Is the Core

Voice isn't a feature in AgoraCare — it is the entire user experience. Every interaction flows through Agora:

• agora_rtc_engine carries all real-time audio (patient ↔ AI agent "Aria")
• The backend starts an Agora Conversational AI agent in the patient's channel with their language + medical context
• Emergency escalation bridges a live nurse into the same Agora channel — human-in-the-loop, in real time
