We do research on how to explore large data sets via voice interfaces. We have a demo online that summarizes trends in the Stack Overflow Developer Survey 2019. Just say "OK Google, talk to Developer Facts" to the Google Assistant to invoke it (e.g., available on Android phones by holding the home button for a few seconds). Ask about a topic (e.g., say "job satisfaction in the US" or "who uses Python") and the system selects the two or three facts that best summarize the data. We appreciate feedback!
