Creating a Voice-Based FAQ Mobile Application

About the Project

Stanford Consulting is a premier preprofessional student-run organization that facilitates interaction between students and companies, while promoting information exchange and experience-sharing among students. Stanford Consulting gives students the opportunity to solve real-world business problems for their client companies. As such, Stanford Consulting helped to consult a medical devices company, referred to as Medical Devices Company or MDC (name changed for privacy purposes).

MDC wants to be seen as a technological leader in the field of medical devices. Cardinal Labs created a minimum viable voice-based frequently asked questions mobile application for patients post-surgery operations.


In order to create a voice-based FAQ mobile application, we identified the following challenges:

• An intuitive user interface for older patients
• Speech-to-text functionality
• Integrations with personalized hospital data


We pursued two routes in order to achieve our goals:

• Designed a mobile application based on existing user interface research with older users
• Researched the best speech-to-text APIs, eventually deciding to use Google Cloud’s API

Based on the user experience research and studies provided by Stanford Consulting, we used React Native to produce a mobile application. Using Google Cloud's speech-to-text functionality, we created a voice-based questioning component for ease of asking medical questions. The mobile application was also developed to be cross-platform, working on both Android and iPhone devices. Two different versions of the application were developed, with one allowing for better integration of hospital specific information and the other a more generalized information source for specific surgeries.
