Carly, a voice-activated health coach for Amazon Echo

Since my team won MIT’s Hacking Medicine hackathon 2 years ago with an app that generates structured documentation from an unstructured patient-doctor interaction (by passively listening and watching the interaction), I’ve taken on the challenge of natural user interfaces. Recently, APIs such as Google’s WebSpeechAPI, which I’ve used in the setting of academic research, proved their ability to convert speech to text with enough fidelity to be useful in real-life applications. With devices like Amazon Echo and wide-range microphones capable of discerning speech through ambient noise, we’ve bypassed the second major hurdle in natural user interfaces.

Now it’s time to start bidding farewell to keyboards, mouses, and ugly software that looks like an Excel spreadsheet. Instead of scrolling through a mind-numbing list of vital signs and lab values in an electronic health record, a provider should simply be able to say: How high did John Doe’s blood pressure get in the past 4 hours? or Trend Jane Doe’s creatinine level over the past week. This is what I mean by natural language interface: software that allows humans to interact with it in the same way humans think, which is through natural speech.
