Walmart Voice Order learns from your past orders so that users don't have to specify exactly which item they want. According to Walmart, if the customer has ordered "Great Value organic orange juice with no pulp" before, they can just say "orange juice" and the app will figure out the user's preferences.

The feature -- which was previously exclusive to Google Assistant -- is available pretty much anywhere if you're steeped in Apple's ecosystem; you can tell Siri to add to your cart via iPhone, iPad, Apple Watch, Mac, HomePod or in your CarPlay-enabled vehicle. While iOS users probably weren't turning green with envy over Android users' ability to order groceries with voice controls, some of them will likely find the feature to be an easier way to get their weekly shopping done. Fans of Alexa probably shouldn't hold their breath, though -- Walmart's direct competition with Amazon means Voice Order will likely only work with Siri and Google Assistant.
