In the future, a conversation with a digital assistant will be indistinguishable from one with a person, according to Rohit Prasad. As the head scientist of Amazon.com Inc.’s Alexa, Mr. Prasad oversees hundreds of engineers working to ensure the AI-powered assistant properly responds to voice commands, whether in Echo speakers, smart microwaves or cars. Mr. Prasad is also developing AI to tackle more complicated issues, like teaching Alexa to converse fluently, whisper responses or suggest that you close the garage door.
