In its latest attempts to battle Amazon, Walmart teamed up with another tech giant to introduce a new way for its customers to buy groceries. According to a blog post by Walmart's senior vice president of digital operations Tom Ward, Walmart will now let those with Google Assistant devices buy groceries just by using their voices. Dubbed Walmart Voice Order, the feature will roll out over the next few weeks to those with Google Home devices along with other Google Assistant-enabled devices including Android smartphones and iPhones.
