Google's AI Assistant aims to transcend the smart speaker

Google's digital voice assistant still trails Amazon in the smart speaker race

Google is expected to announce updates to its voice assistant and smart home products Tuesday at its annual developers conference in Mountain View, California.

Google Assistant still comes second behind Amazon in the smart speaker race. But the company launched its product nearly two years after Amazon released Echo and has gained considerable ground on its rival.

Google has expanded Assistant to more than 1 billion devices. It released a feature earlier this year that allows Assistant to call and make restaurant reservations for you, a technology that is a first of its kind in the market.

Google I/O kicks off Tuesday morning.
