A Promise Made It has been almost 5 years since Google first showed off their voice assistant Google Duplex. Dressed casually in a bomber jacket, Sundar Pichai waltzed onto the stage and enthralled the audience with actual phone calls made by a piece of technology to book a haircut appointment at a salon. The interaction was mind-blowing. Not only was the appointment set up, but the nuances of a human conversation were adopted, so much so that the salon representative had no idea that she was not speaking to a real person. Pichai went on to say that the technology had elements of natural language understanding, deep learning, text-to-speech, and many others. The premise was set up beautifully for the possibilities of Artificial Intelligence (AI) or more specifically, conversational AI in this context.
