Abstract: Dialog management may be performed by a voice assistant system where the dialog pertains to a shopping experience that enables a user to order one or more items using voice-activated commands provided during a dialog exchange with the voice assistant device. In some embodiments, the personal assistant system may enable a user to order items, select fulfillment details for the items, pay for the items, and/or perform other related tasks to enable the user to obtain the items using voice activated commands and without reliance on a graphical user interface. In various embodiments, the personal assistant system may select fulfillment options for a user, or may assign fulfillment to a particular service based on audio responses received from a user. The personal assistant system may leverage prior user interaction data, user profile information, and/or other user information during interaction with a user to supplement voice inputs received from a user.
