Domino's Pizza has taken half a million orders through it's 'voice ordering' app

"Domino’s Pizza’s virtual ordering assistant Dom, which lets consumers dictate orders via mobile devices while on-the-go, has reached a half-million orders since its 2014 launch, suggesting that more food brands should consider investing in voice ordering technology.
The mobile application was created to increase personalization as more consumers turn to digital channels to place orders for food and beverage items. Although Domino’s does also offer customers the ability to order via a mobile Web site or the brand’s app, Dom’s catchphrases have proven to be popular and have contributed to the company’s milestone of 50 percent of sales coming from digital platforms."
