Voice assistants in the car pre-date Siri on iPhone by a decade and smart speakers in the home by even longer. The use cases bring obvious benefits because voice allows drivers to execute key activities in the car while keeping their eyes on the road and hands on the wheel. Recorded live at the first Voice of the Car Summit, Arianne Walker discusses Amazon's Alexa Auto strategy, Adam Emfield reveals what Nuance has learned by bringing voice into the cabins of every major automaker, and Rashmi Rao of Harman describes how the infotainment system is the central hub for voice in the car and is arbitrating user queries before sending them to multiple assistants.
