Walmart will let customers order groceries by voice through Google’s smart-home assistant.

With the new Walmart Voice Order service, the company is building across platforms with partners like Google, to help its customers simply say the word to have Walmart help them shop.

Beginning this month, Walmart's customers can say, ”Hey Google, talk to Walmart” and the Google Assistant will add items directly to their Walmart Grocery cart. Walmart says that the system will use information from customers' prior purchases in order to quickly and accurately identify the items customers are asking for.

And since the Assistant is now available on more than a billion devices, including Smart Displays like Google Home Hub, Android phones, iPhones, watches and more, Walmarts' customers can manage their shopping carts while they’re at home or on the go.

For Alphabet Inc.’s Google, teaming with the world’s largest retailer could help its digital home assistant bridge the gap with Amazon’s Echo device, commonly known as Alexa.

Rival Kroger Co. has also unveiled voice-shopping capabilities through Google.
